South America
Twelve countries. Three subregions. From the Caribbean coast to Tierra del Fuego, threaded by the Andes and the Amazon.
South America runs from the Caribbean coast of Colombia and Venezuela south through the Andes and the Amazon Basin to the sub-Antarctic islands of Chile and Argentina — some 7,400 kilometres from north to south. It is the world's fourth-largest continent, home to the Amazon rainforest and the world's longest mountain range, and the fifth-most-populous with roughly 438 million people. Nations Atlas covers every one of its 12 sovereign countries. Neighbours: North America, Africa (across the South Atlantic).
What defines South America
A single continent unified by two vast geographic systems — the Andes and the Amazon — and split by history into Iberian and non-Iberian, Andean and lowland, tropical north and temperate south.
South America is the world's fourth-largest continent by area (approximately 17.7 million square kilometres, about 12 percent of Earth's land) and the fifth-largest by population (approximately 438 million). It runs from Punta Gallinas on Colombia's Caribbean coast — the northernmost point of the South American mainland — some 7,400 kilometres south to Cape Froward and the sub-Antarctic islands of Chilean Patagonia. The Panama-Colombia border marks the continent's northern boundary with North America; the Southern Ocean bounds the south.
Two geographic systems dominate the continent. The Andes — the world's longest continental mountain range at roughly 7,000 kilometres — runs down the Pacific spine through Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina, containing the highest peaks in the Western Hemisphere and the world's driest desert (the Atacama in northern Chile). The Amazon Basin — the world's largest tropical rainforest at roughly 6 million square kilometres — spans nine countries, with about 60 percent of it in Brazil. The Pampas grasslands of Argentina, Uruguay, and southern Brazil form one of the world's great cattle-country regions. Patagonia spans southern Argentina and Chile with sub-polar glaciers.
The continent's civilisational depth is anchored on the Andes. The Inca Empire — one of the largest pre-industrial empires in world history — controlled a Pacific coastal-highland zone from present-day Colombia to Chile at its early 16th-century peak; its capital Cusco and the mountain settlement of Machu Picchu remain among the world's most-visited archaeological sites. Pre-Inca civilisations included the Moche, Nazca, Wari, Tiwanaku, and Chavín. Beyond the Andes, complex urban civilisations flourished in the Amazon Basin (recently rewritten by lidar-based archaeology showing far more populous pre-Columbian settlement than previously thought). Living Indigenous peoples — Quechua and Aymara across the Andes, Guaraní across Paraguay and adjacent regions, Mapuche in southern Chile and Argentina, and dozens of Amazonian peoples — remain central to modern national cultures, particularly in Bolivia, Peru, Ecuador, and Paraguay.
How many countries are in South America?
The 12 countries are: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela.
What isn't in the count of 12
French Guiana is South American in geography but is an overseas region of France — as much a part of France as any European department, using the euro, and inside the European Union. It is covered under our France page. The Falkland Islands (Islas Malvinas) are a British Overseas Territory in the South Atlantic whose sovereignty is claimed by Argentina; the islands are covered under our United Kingdom page's territories section. South Georgia and the South Sandwich Islands are another British Overseas Territory in the sub-Antarctic. The ABC islands off the Venezuelan coast (Aruba, Bonaire, Curaçao) are Dutch Caribbean territories and are covered under our Netherlands and North America pages.
Trinidad and Tobago, just off the Venezuelan coast, is geographically closer to South America than to most other Caribbean islands but is politically and culturally Caribbean and part of CARICOM — Nations Atlas covers it under our North America hub. All 12 sovereign South American countries are members of the Organization of American States.
South American trade blocs untangled
Mercosur, CAN, Pacific Alliance, UNASUR, CELAC — five overlapping regional organisations that get used interchangeably by outsiders. Here is what each actually does.
South America has more regional integration organisations per capita than almost any other continent. The organisations overlap, compete, and — in several cases — have gone dormant or reversed. Below are the ones you will actually encounter in news coverage and travel logistics.
| Bloc | Type | Members / status |
|---|---|---|
| Mercosur | Customs union and common market. Founded 1991. The dominant SA trade bloc. | Full members: Argentina, Brazil, Paraguay, Uruguay, Bolivia (full member from July 2024). Suspended: Venezuela. Associate members: Chile, Colombia, Ecuador, Guyana, Peru, Suriname. Free movement for citizens using national ID. |
| Andean Community (CAN) | Free trade area and integration project. Founded 1969. Predates Mercosur. | Full members: Bolivia, Colombia, Ecuador, Peru. Associate members: Argentina, Brazil, Chile, Paraguay, Uruguay. Overlaps significantly with Mercosur since Bolivia is in both. |
| Pacific Alliance | Free trade and integration bloc. Founded 2011. Pacific-facing, market-oriented. | Members: Chile, Colombia, Peru, plus Mexico (which is in North America). Strong emphasis on trade with Asia. Costa Rica has been in accession process. Countries removed most tariffs among themselves. |
| UNASUR | Political and diplomatic union. Founded 2008. Largely defunct. | Was designed to cover all 12 South American countries. Most members suspended participation between 2018-2020 amid political disputes. Currently in a limbo state; some countries have rejoined, others left permanently. |
| PROSUR | Political forum. Founded 2019 as a right-leaning replacement for UNASUR. | Originally launched by Chile, Argentina, Brazil, Colombia, Ecuador, Paraguay, Peru, Guyana. Political membership has shifted with government changes across the region; effectively less active than intended. |
| CELAC | Continent-wide political forum. Founded 2011. Covers all Latin America and the Caribbean. | All 33 Latin American and Caribbean countries — including Mexico, Central America, Cuba, and all sovereign Caribbean nations. Notable for explicitly excluding the US and Canada. Diplomatic dialogue forum rather than a trade or integration bloc. |
| OAS | Continent-wide diplomatic organisation. Founded 1948. | All 35 sovereign countries in the Americas including US and Canada, headquartered in Washington. Diplomatic, human rights, and dispute-resolution functions. Cuba's membership is suspended. |
Two practical takeaways. First: Mercosur is the one that matters most for trade, movement, and business logistics — and Mercosur members can travel between one another using national ID cards without passports. Second: the region's political blocs (UNASUR, PROSUR, CELAC) have shifted repeatedly with government changes; expect this to continue.
In December 2024, the European Union and Mercosur announced political conclusion of a landmark trade agreement negotiated over 25 years. If ratified — a process ongoing through 2026 and facing agricultural-sector opposition in France, Poland, and elsewhere — it would create one of the world's largest free-trade zones, covering roughly 800 million people and about a quarter of global GDP. It is the most consequential regional integration development in South America in a generation.
The three subregions of South America
Three subregions with sharply different geographies, cultures, and economies — the Pacific-facing Andean spine, the Atlantic-facing Amazon and Guianas, and the temperate Southern Cone.
Andean South America
5 countriesFive countries running down the Pacific spine of the continent, defined by the Andes mountain range and — for four of them — a strong Indigenous demographic and cultural weight. From north to south: Colombia, Ecuador, Peru, Bolivia, and Chile. The Andes give this region the highest peaks in the Western Hemisphere (Aconcagua at 6,961 metres in Argentina, technically Southern Cone), the world's highest capital city (La Paz, Bolivia, at ~3,640 m), Lake Titicaca (highest navigable lake in the world), and the world's driest desert (Atacama, northern Chile).
The Andean countries hold the continent's densest Indigenous populations. Quechua — the Inca administrative language — is spoken by around 8 to 10 million people across Peru, Bolivia, Ecuador, and parts of Colombia and Argentina, and is an official language of Peru and Bolivia. Aymara is spoken by around 2 million around Lake Titicaca in Bolivia and Peru. Kichwa is Ecuador's main Indigenous language. Bolivia identifies constitutionally as a "plurinational state" and recognises 37 official languages — the most of any country in the Americas. Ecuador and Peru have also expanded Indigenous cultural and political recognition significantly over the past two decades.
Economically the region splits between market-oriented economies (Chile, Colombia, Peru — all Pacific Alliance members) and more state-oriented models (Bolivia; Ecuador has moved between models). Colombia's economy has grown into one of the region's largest, with Bogotá and Medellín as major regional centres. Chile is the region's most-developed economy and one of Latin America's most-developed overall. Peru's economy runs on mining, agriculture, and — increasingly — tourism. Bolivia's economy depends heavily on natural gas and minerals. Ecuador dollarised its economy in 2000 (uses USD) and depends significantly on oil and remittances.
Brazil, the Amazon, and the Guianas
4 countriesFour countries anchored on the Amazon Basin and the Atlantic-facing north of the continent — Brazil, Venezuela, Guyana, and Suriname. Brazil dominates the group and the continent, holding roughly half of South America's land area, half its population, and roughly 60 percent of the Amazon rainforest. It is the continent's only Portuguese-speaking country and one of only two of the world's ten most-populous countries in the Western Hemisphere (the other being the United States).
Brazil is functionally its own subregion given its scale — bigger by area than the contiguous United States, home to São Paulo (largest city in the Southern Hemisphere) and Rio de Janeiro (Christ the Redeemer, Copacabana, one of the world's most-photographed urban landscapes), plus the deeply African-influenced culture of Salvador and Bahia, the Amazon centre of Manaus, and the border-region Pantanal wetlands. Brazilian cuisine (feijoada, moqueca, açaí, brigadeiros), music (samba, bossa nova, forró, MPB, funk carioca), and football culture have shaped global culture at a scale disproportionate even to Brazil's very large size.
The Guianas — Guyana, Suriname, and French Guiana (an overseas region of France) — are the exception to Latin America in South America. Guyana is English-speaking (former British Guiana), a member of CARICOM, and — since substantial offshore oil discoveries from 2015 onwards — currently one of the world's fastest-growing economies. Suriname is Dutch-speaking (former Dutch Guiana), also a CARICOM member, and has a strikingly diverse population (Hindustani, Javanese, Maroon, Creole, Indigenous, Chinese, and others). Both are covered by rainforest across most of their territory. Venezuela has been in a compounded political and economic crisis since 2014; its 2024 disputed election deepened the situation, and current travel to the country is not advised by most Western governments.
The Southern Cone
3 countriesThree countries covering the temperate southern reaches of the continent — Argentina, Uruguay, and Paraguay. Chile is often included in Southern Cone classifications given its long Pacific coast reaching to Tierra del Fuego; Nations Atlas groups Chile with Andean South America editorially given the mountain range's dominance in Chilean geography, but the Southern Cone classification is defensible either way.
The Southern Cone's cultural distinctiveness within Latin America comes from its heavy 19th-century European immigration — particularly Italian and Spanish, plus significant German, French, British, and later Middle Eastern and Eastern European. Argentina and Uruguay in particular were shaped by mass European immigration on a scale comparable to the United States, producing a demographic and cultural character sometimes described as "the most European part of Latin America." Buenos Aires and Montevideo bear the architectural stamp; local cuisine centres on beef, wine, dulce de leche, and Italian-derived pasta and ice cream traditions. Tango — born in the working-class districts of Buenos Aires and Montevideo in the late 19th century — remains the defining Southern Cone musical form.
Paraguay is a special case within the Southern Cone. It is landlocked and has a demographic profile far more indigenous than its neighbours — Guaraní is a co-official language of Paraguay along with Spanish and is spoken by the majority of the population as a first or second language, making Paraguay the most linguistically Indigenous of any non-Andean country in Latin America. Uruguay is the smallest of the three but is consistently one of the most-developed democracies in Latin America — first country in the world to legalise recreational cannabis nationally (2013), and a regional leader on renewable energy. Argentina is the region's giant, home to tango, football, wine (Mendoza), beef (asado), Patagonian glaciers, and the world's southernmost city (Ushuaia, Tierra del Fuego).

Population figures are rounded mid-2024 United Nations estimates verified for 2026. Bolivia has two capitals: Sucre is the constitutional capital and seat of the Supreme Court; La Paz is the seat of the executive and legislature. Bolivia constitutionally identifies as a plurinational state and recognises 37 official languages — the number in the "official languages" column reflects the four most-spoken (Spanish plus three Indigenous). Ecuador adopted the US dollar as official currency in 2000 following a banking crisis. Venezuela's population figure predates the substantial 2015-2025 emigration wave; UNHCR estimates around 7.7 million Venezuelans have left the country since 2015, one of the largest global displacement crises.

South America by the numbers
Three ranked lists that answer the questions readers ask most often about the continent.
Most populous countries
Largest by area
Population figures are UN 2024 estimates rounded for readability. Venezuela's true resident population is difficult to establish precisely given ongoing emigration — the UNHCR estimates ~7.7 million Venezuelans have left the country since 2015. Argentina and Venezuela both operate under high or hyper-inflation conditions that make peso-denominated GDP figures unreliable, so we present GDP orderings by tier rather than exact rank. Guyana's economy has grown at rates above 30 percent per year since substantial offshore oil production began in 2020, making it (in some years) the world's fastest-growing economy. Country pages carry more precise, sourced figures.
Cultural threads across South America
Themes that surface across the continent — and the sharp regional and national differences that make each country its own place.
Indigenous cultures: still shaping national life
Indigenous peoples are constitutive to modern South American national cultures at a scale that exceeds most of the rest of the Americas. Quechua — the Inca administrative language — is spoken by around 8 to 10 million people across the Andes and is an official language of Peru and Bolivia. Aymara is spoken by around 2 million around Lake Titicaca. Guaraní is co-official in Paraguay and Bolivia; the majority of Paraguayans speak it as a first or second language, making Paraguay unique in the Americas for its Indigenous linguistic character across the whole population.
Mapuche peoples across southern Chile and Argentina — never fully conquered by the Inca or the Spanish — hold contemporary political and cultural weight. Amazonian peoples across Brazil, Peru, Colombia, Ecuador, Bolivia, Venezuela, Guyana, and Suriname number in the hundreds of distinct groups, from more assimilated communities to a small number of uncontacted or voluntarily-isolated groups protected under law. Bolivia constitutionally identifies as a "plurinational state" and recognises 37 official languages — the most of any country in the Americas. Our country pages cover Indigenous cultures and etiquette per our cultural sensitivity policy.
The Amazon: a shared inheritance and a shared threat
The Amazon rainforest covers roughly 6 million square kilometres, an area two-thirds the size of the contiguous United States. It spans nine countries — Brazil (approximately 60 percent), Peru (13 percent), Colombia, Venezuela, Bolivia, Ecuador, Guyana, Suriname, plus French Guiana — and holds an estimated 10 percent of the world's known biodiversity. Roughly 400 Indigenous groups live within it, including several that have chosen voluntary isolation from wider national society.
The Amazon is under sustained pressure from deforestation (cattle ranching, soy cultivation, illegal mining, road construction), climate change (increased drought years, altered rainfall patterns), and — in some regions — active armed group presence. Deforestation rates fell substantially in Brazil during the first Lula government (2003-2010), rose sharply under the Bolsonaro government (2019-2022), and have fallen again since 2023. The rainforest is one of the world's most-studied and most-contested environmental frontlines. Ecotourism through Iquitos (Peru), Manaus (Brazil), and Puerto Maldonado (Peru) is well-developed; specialist operators can arrange serious wildlife itineraries.
Cuisine: from ceviche to asado
South American cuisines are among the world's most-globally-influential at present. Peru is currently one of the most-celebrated food destinations in the world — Lima is regularly rated among the world's top three food cities. Ceviche (raw fish cured in citrus with onion, chilli, and cilantro) is a UNESCO-recognised Peruvian tradition. Peruvian food fuses Indigenous, Spanish, African, Chinese (chifa), and Japanese (Nikkei) influences into something distinct.
Argentina and Uruguay anchor South American beef culture — the asado (barbecue), choripán, and Malbec / Tannat wine traditions. Brazil brings feijoada (bean and pork stew), moqueca (Bahian fish stew), pão de queijo (cheese bread), açaí, and the churrasco tradition. Colombia and Venezuela share arepas (though the traditions differ meaningfully by country). Ecuador's llapingacho (potato-cheese patties), Bolivia's salteñas (baked empanada-like pastries), Paraguay's chipa (cheese bread) and terere (cold yerba mate), and Chile's completo (loaded hot dog) and pisco sour anchor national cuisines that are increasingly getting the global attention they deserve.
Music: tango, samba, cumbia — and reggaeton
South America has produced several of the world's defining musical traditions. Tango — born in the working-class port districts of Buenos Aires and Montevideo in the late 19th century — is one of two SA musical forms on UNESCO's intangible cultural heritage list. Samba — the Afro-Brazilian rhythm at the centre of Rio de Janeiro's Carnival — is the other. Bossa nova emerged from samba in 1950s Rio and shaped mid-century global jazz. MPB (Música Popular Brasileira), forró, axé, and Brazilian funk carioca continue Brazil's disproportionate contribution to global music.
Cumbia — originating on Colombia's Caribbean coast — has spread across Latin America to become one of the most-danced rhythms in the region, with distinct national variants in Peru (cumbia peruana), Argentina (cumbia villera), and Mexico. Salsa has strong South American traditions in Colombia (Cali is one of the world's salsa capitals) and Venezuela. Reggaetón — born in Puerto Rico with substantial roots in Panama — has become one of the world's dominant genres and has strong South American production centres in Colombia (Medellín is now a global reggaetón hub, home to J Balvin, Karol G, and others). Andean folk music (charango, quena, zampoña) remains vital across Peru, Bolivia, and Ecuador.
Football (fútbol / futebol) as national identity
South America has produced more football World Cup titles per capita than any other continent — Brazil's five (1958, 1962, 1970, 1994, 2002), Argentina's three (1978, 1986, 2022), and Uruguay's two (1930, 1950). The Brazil-Argentina rivalry is one of the most-followed sporting rivalries in world sport. Diego Maradona (Argentina), Pelé (Brazil), Lionel Messi (Argentina), and Ronaldinho (Brazil) rank among the most-recognised sports figures in the world.
Beyond the two giants, football culture runs deep across the continent. The Copa Libertadores (South American club football's premier tournament) draws intensity comparable to Europe's Champions League. Colombia, Chile, Peru, Ecuador, Paraguay, Venezuela, and Bolivia all have serious footballing traditions. The Copa América — contested since 1916 — is the oldest international football tournament in the world. Travellers visiting any South American country during a major international match will see the continent's football culture at its most vivid.
Migration: European inflow, Venezuelan outflow
Two migration flows shape the modern demographic character of South America. The first is the 19th-and-early-20th-century European mass migration — particularly Italian and Spanish — that reshaped the Southern Cone. Argentina received around six million European immigrants between 1857 and 1950, giving Buenos Aires a demographic and cultural character sometimes described as "the Paris of South America." Uruguay, southern Brazil (São Paulo, Rio Grande do Sul), and Chile experienced similar though smaller flows. Italian-descended surnames dominate the Argentina and Uruguay national football teams; Italian food traditions run through both.
The second — active now — is the Venezuelan exodus. Approximately 7.7 million Venezuelans have left the country since 2015, according to UNHCR estimates. The main destinations have been Colombia (~2.8 million), Peru (~1.5 million), Ecuador, Chile, Argentina, Brazil, plus the United States and Spain. It is one of the largest displacement crises in the world today and has reshaped urban demographics across the continent. Historical Bolivian and Paraguayan migration to Argentina, and Peruvian migration to Chile, have also been significant regional flows.
Best time to visit South America by region
South America is largely Southern Hemisphere, so seasons run opposite to Europe and North America. Timing depends sharply on which part of the continent you're visiting.
| Region | Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Colombia & Venezuela Caribbean coast | ● | ● | ● | ● | ◐ | ◐ | ◐ | ◐ | ◐ | ✗ | ◐ | ● |

Andean dry season (May-September) is the peak window for Machu Picchu (though it draws big crowds July-August), Bolivia's Salar de Uyuni salt flats, and much of the Andean highland circuit. December-March is the rainy season across most of the Andes — some Inca Trail sections close for maintenance in February. The Amazon has a wet season roughly November-May and a drier season June-October; the wetter months (higher water) can actually be better for river-based wildlife access on some routes, while the drier months favour trekking-based access.
Cultural timing. Brazil's Carnival (the four days before Ash Wednesday, usually February or early March) is one of the world's great festivals — Rio de Janeiro, Salvador, and Recife/Olinda each hold different traditions. Argentina's peak wine harvest in Mendoza runs February-April. Peru's Inti Raymi (Inca sun festival) in Cusco falls on June 24. Uruguay's Carnival — the world's longest — runs 40 days from late January. Ecuador's Galápagos islands are visitable year-round; different months favour different wildlife (mating seasons, migration patterns). Country pages carry detailed festival calendars.
Getting around South America
A continent of large countries and challenging geography — the Andes, the Amazon, and Patagonia all impose limits on overland travel that shape realistic itineraries.
Air. Air travel is the practical default for anything beyond a single-country trip. Brazil's GOL, Azul, and LATAM (Chilean-based, the region's largest airline) dominate the market. Panama City (Copa Airlines' Tocumen hub, technically in North America) is the key connector between North and South America and holds one of the widest South American route networks. Lima and Bogotá are also major regional hubs. LATAM's São Paulo, Santiago, and Lima hubs anchor most cross-continental routes. Direct flights between South American countries can sometimes be scarce even between neighbouring capitals — trip planners should check for necessary connections.
Long-distance buses are the continent's other great transport backbone and are excellent in most countries. Argentina's cama and semi-cama long-distance buses (Andesmar, Vía Bariloche, Chevallier) are famously comfortable — often better than Amtrak's US equivalent. Peru's Cruz del Sur runs a similar high-standard operation. Brazil's long-distance bus network covers vast distances (São Paulo to Recife is a 40-hour trip). Chile's Turbus and Pullman Bus cover the country's north-south length. Overnight buses can save both time and a night's accommodation.
Rail is limited but not absent. Peru's Machu Picchu train (Inca Rail, PeruRail) from Cusco or Ollantaytambo to Aguas Calientes is essential for standard Machu Picchu visits. The Perurail Andean Explorer and the Belmond Andean Explorer offer luxury rail journeys through the Andes. Bolivia has some tourist rail. Chile's Metro Santiago and Argentina's Subte Buenos Aires are functional urban systems. Brazil's São Paulo metro is Latin America's most-used metro. Most intercity rail across the continent, however, is either non-existent or has been converted to freight-only.
Cross-border travel. Mercosur citizens (from Argentina, Brazil, Paraguay, Uruguay, plus Bolivia as full member since 2024) can move between member countries using national ID cards. For most Western visitors, land border crossings are generally straightforward — the classic South American backpacker circuits (Cartagena to Ushuaia, Rio to Machu Picchu) rely on it. Bolivia-Chile-Argentina triangle crossings via the Salar de Uyuni are popular. The Colombia-Panama land crossing through the Darién Gap is not viable for tourists — this jungle area has no roads and is currently a major migration corridor with substantial risks. Overland travel between Colombia and Panama requires either flying or boat travel around the gap. Amazon river transport — including the multi-day boat routes between Manaus and Belém in Brazil, or between Peru and Brazil via Iquitos — is a legitimate travel option requiring time and flexibility.
How safe is South America?
Safety varies enormously by country and by region within countries. The honest picture with current exceptions.
Safer countries. Uruguay and Chile consistently rank among the safest countries in the Americas by international measures. Argentina is largely safe in main tourist areas — Buenos Aires, Mendoza, Bariloche, Ushuaia, and the Patagonian circuits — with normal urban precautions. Paraguay is generally safe. Small-country Guyana and Suriname have low overall tourist crime.
Countries with sharp regional variation. Colombia has transformed dramatically since the 2016 peace deal with the FARC; Bogotá, Medellín, Cartagena, and the Coffee Triangle are broadly safe for standard travel. Specific regions — parts of Norte de Santander, Chocó, Cauca, and Nariño — retain substantial security concerns due to dissident guerrilla groups (ELN, FARC dissidents) and cartel activity. Always check current government advisories. Peru is safe in the main tourist circuit (Lima, Cusco, Sacred Valley, Machu Picchu, Arequipa, Lake Titicaca); the Amazon basin and VRAEM region carry specific advisories. Brazil is safe in most tourism zones — Rio de Janeiro, São Paulo, Salvador, Foz do Iguaçu, Amazonas — but requires favela-area awareness and standard urban vigilance.
Ecuador has seen serious security deterioration since 2023 due to cartel-related violence, concentrated in the coastal cities of Guayaquil, Esmeraldas, Manta, and Duran. The government declared a "state of internal armed conflict" in January 2024 and has continued security-focused policies. Andean tourist destinations (Quito, Cuenca, Otavalo, Baños) and the Galápagos Islands remain relatively insulated from the coastal crisis. Current government advisories from the US State Department, UK FCDO, Canadian, and Australian governments should be consulted for the specific regions and cities you plan to visit.
Venezuela has been in a compounded political and economic crisis since 2014, deepened by the disputed July 2024 presidential election and the ongoing Maduro government. Most Western governments — US State Department, UK FCDO, Global Affairs Canada, Australian DFAT — currently advise against all or non-essential travel. Hyperinflation, shortages of basic goods, high crime rates, arbitrary detention risks including for foreigners and journalists, and unreliable services shape the current environment. Nations Atlas's Venezuela coverage continues for reference but should be read alongside current advisories.
Amazon regions across all nine Amazonian countries carry specific safety considerations — including armed group presence in some border zones (Brazil-Colombia-Peru triple frontier, Peru-Colombia-Ecuador border areas), illegal mining and logging operations, and the practical challenges of remote-area travel. Reputable specialised operators handle serious Amazon itineraries; independent travel deep into the forest is not for most visitors.
Before any trip, consult your government's current travel advisory — the US State Department, UK Foreign Office, Global Affairs Canada, or the Australian DFAT — for the specific countries and regions you plan to visit. Our country pages carry current safety sections with the same advisory links.
Money and connectivity across South America
Card acceptance is high in urban areas. Argentina and Venezuela both require inflation-aware planning.
Currency landscape. Nine of the 12 South American countries use their own national currency — the Argentine peso, Bolivian boliviano, Brazilian real, Chilean peso, Colombian peso, Guyanese dollar, Paraguayan guaraní, Peruvian sol, Surinamese dollar, Uruguayan peso, and Venezuelan bolívar. Ecuador is the exception in South America — it uses the US dollar as its official currency, having dollarised in 2000 following a banking crisis. Card acceptance is high in most urban areas across the continent; ATMs are widely available with the usual caveats about foreign-card fees.
Argentina has been in a sustained inflation crisis since 2018, with annual inflation reaching over 200 percent through 2023-2024 before beginning to decline under the Milei government's economic reforms. This creates real complexity for visitors. Historically, the "blue dollar" black market offered rates two to three times better than the official rate; the Milei government has moved to unify exchange rates, but the situation remains fluid. Bring some cash (US dollars in good condition), use debit cards where advantageous, and check current exchange dynamics before your trip. Prices in pesos change rapidly — restaurants may reprint menus weekly.
Venezuela's bolívar has undergone multiple hyperinflation episodes since 2016 and multiple redenominations (the currency has lost 14 zeros in that period). The US dollar is now widely used unofficially in daily transactions across the country in what economists call "de facto dollarisation." Given the current advisory situation, travel-specific money guidance is less relevant than it would otherwise be — anyone travelling to Venezuela requires specialist current guidance from local contacts.
Connectivity. Mobile coverage is generally excellent in South American urban areas and reasonable across most tourist-frequented regions. Amazon Basin and remote Patagonian coverage is limited. eSIM providers (Airalo, Holafly, Nomad) cover all South American countries at reasonable rates and are the easiest solution for travellers crossing multiple countries. Regional roaming plans (many Argentine, Brazilian, and Chilean carriers offer intra-South-America roaming) are worth checking. Free WiFi is common in hotels, cafés, and airports across the continent. Our eSIM guide compares current options.

Contested territories and how we cover them
South America has three significant unresolved territorial questions — and one deeply-shaped historical loss with continuing political weight.
Nations Atlas covers all 12 sovereign countries of South America. We take editorial care around territorial disputes: naming conventions, sovereignty framing, and situations where the international community and disputing parties disagree. Below are the four significant cases in South America.
Essequibo (Venezuela / Guyana)
Venezuela claims sovereignty over the Essequibo region — approximately two-thirds of Guyana's land area, west of the Essequibo River — on the basis of the 1899 arbitral award (which Venezuela declared null in 1962) and the 1966 Geneva Agreement between Venezuela, Britain (as colonial administrator of British Guiana), and what became Guyana. The dispute intensified dramatically after substantial offshore oil discoveries in Guyanese waters from 2015 onwards, and became acute in December 2023 when Venezuela held a referendum claiming domestic support for annexation. The International Court of Justice is currently hearing the case. Guyana administers the region and is recognised internationally as the sovereign. Nations Atlas covers the Essequibo under our Guyana page while noting the Venezuelan claim.
Falkland Islands / Islas Malvinas (UK / Argentina)
The Falkland Islands (called Islas Malvinas in Spanish) are a British Overseas Territory in the South Atlantic, approximately 500 km off Argentina's Patagonian coast. The UK has administered the islands continuously since 1833; Argentina claims sovereignty on the basis of geographic proximity, prior Spanish colonial claim, and 19th-century Argentine settlement predating the British takeover. The dispute led to the Falklands War in April-June 1982, in which Argentina briefly occupied the islands before UK forces retook them; approximately 900 people died. A 2013 referendum saw 99.8 percent of Falkland Islanders vote to remain a British Overseas Territory. Argentina continues to claim sovereignty; the UK considers the matter settled. Nations Atlas covers the islands under our United Kingdom page's territories section.
Bolivia's Pacific access claim
Bolivia lost its Pacific coast to Chile in the War of the Pacific (1879-1884). The territorial loss — including what became Chile's Antofagasta region — left Bolivia landlocked. Bolivia has maintained a formal claim to sovereign Pacific access ever since. The dispute is diplomatic rather than active-military, but it has consequential political weight: Bolivia maintains a Ministry of Maritime Affairs and a symbolic navy, and the "maritime claim" is a foundational element of Bolivian national identity. The International Court of Justice ruled against Bolivia in 2018 on the specific legal question of whether Chile had a binding obligation to negotiate access, but did not rule out future negotiation. The Chile-Bolivia border is not itself in dispute.
The Venezuelan crisis and diplomatic recognition
Beyond territorial disputes, Venezuela's political situation is itself a matter of ongoing international non-consensus. The July 2024 presidential election result — declared won by incumbent Nicolás Maduro — has been rejected by most Western governments, the European Union, and the majority of Latin American governments outside Cuba and Nicaragua. Multiple countries have severed or downgraded diplomatic relations with the Maduro government. Nations Atlas covers Venezuela as a sovereign country under its de facto government while noting the recognition dispute and its practical consequences for travellers and business.

South America FAQ
Ten questions readers ask most often about South America as a whole.
There are 12 sovereign countries in South America. Nations Atlas covers all of them across three subregions: Andean South America (Colombia, Ecuador, Peru, Bolivia, Chile), the Amazon Basin and the Guianas (Brazil, Venezuela, Guyana, Suriname), and the Southern Cone (Argentina, Uruguay, Paraguay). French Guiana is not sovereign — it is an overseas region of France and is covered under our France page. The Falkland Islands (Islas Malvinas) are a British Overseas Territory whose sovereignty is disputed by Argentina.
Mostly, but not entirely. Latin America is a cultural and linguistic region covering the countries in the Americas where Romance languages (Spanish, Portuguese, French) predominate. Ten of South America's 12 countries fit that definition: nine Spanish-speaking (Argentina, Bolivia, Chile, Colombia, Ecuador, Paraguay, Peru, Uruguay, Venezuela) plus Portuguese-speaking Brazil. The two exceptions are English-speaking Guyana and Dutch-speaking Suriname, which are in South America geographically but not part of Latin America culturally. Latin America also extends into North America — Mexico, Central America, and the Spanish-speaking Caribbean plus Haiti.
Portuguese is the sole official language of Brazil and is spoken by essentially all of its ~215 million people. Brazil is the only Portuguese-speaking country in the Americas and the largest Portuguese-speaking country in the world by a wide margin — around three times the combined populations of Portugal and all other Portuguese-speaking African and Asian countries. Brazilian Portuguese differs from European Portuguese in accent, vocabulary, and some grammar; the two are mutually intelligible. Brazil also has approximately 230 living Indigenous languages spoken by around one million people. Spanish is not widely spoken across Brazil, despite the country's neighbours being almost entirely Spanish-speaking.
It depends on what you want. For a classic South America introduction covering Machu Picchu, the Andes, and Amazon access: Peru. For beach, food, and vibrant urban culture: Colombia (Cartagena, Medellín, Bogotá). For wine, football, tango, and European-feel cities: Argentina. For UNESCO-scale wilderness with Patagonian glaciers and Torres del Paine: Chile. For the Amazon and world-class urban culture: Brazil (Rio, São Paulo, Salvador). For a compact, welcoming introduction: Ecuador (Galápagos plus Quito plus the Andes in one manageable trip). For a small, safe, deeply-cultured destination: Uruguay.
Most Western passport holders (US, Canadian, UK, EU, Australian, Japanese) get visa-free access to almost all South American countries for tourist visits of 30 to 90 days. Some countries charge a reciprocity fee for US and Canadian passport holders — Bolivia is the main current example. Suriname operates an e-tourist card system. Brazil restored visa-free access for most Western passport holders in 2025 after briefly reintroducing requirements. Mercosur citizens (from Argentina, Brazil, Paraguay, Uruguay, plus Bolivia as full member since 2024) can move between member countries using national ID cards. Country-specific requirements can change — check your government's current advisory before travel. See our Mercosur visa guide for detailed country-by-country requirements.
South America is largely a Southern Hemisphere continent, so its seasons run opposite to those in Europe and North America. December through March is southern summer — best for Patagonia, southern Chile and Argentina, and Uruguay's beach coast. June through September is southern winter but is the dry season across much of the Andes, making it the best window for Machu Picchu, La Paz, Bolivia's salt flats, and much of Peru's altitude circuit. Amazon Basin has a wet season roughly November to May and a drier season June to October — the wetter months are actually easier for wildlife viewing on some rivers. Colombia and Venezuela on the Caribbean coast are best December to April. The Galápagos are visitable year-round with different wildlife by season.
Safety varies dramatically by country and region within countries. Uruguay and Chile consistently rank among the safest countries in the Americas by international measures. Argentina, Peru, and Colombia are safe in main tourist circuits with normal urban precautions; Colombia has transformed dramatically since the 2016 FARC peace deal though some regions remain problematic. Brazil is safe in most tourism zones but requires favela-area awareness. Ecuador has seen serious security deterioration since 2023 due to cartel-related violence in coastal cities. Venezuela faces a substantial ongoing crisis with widespread travel advisories against most travel. Bolivia, Paraguay, Guyana, and Suriname are generally safe with sensible precautions. Always check your government's current advisory before travel.
Most Western governments currently advise against all or non-essential travel to Venezuela. The country has been in a compounded political and economic crisis since 2014, deepened by the disputed July 2024 presidential election and the ongoing government of Nicolás Maduro. Hyperinflation, shortages of basic goods, high crime rates, arbitrary detention risks for foreigners including journalists, and unreliable services all shape the current environment. Approximately 7.7 million Venezuelans have left the country since 2015 — one of the largest displacement crises in the world. Nations Atlas's Venezuela coverage continues for reference but should be read alongside current advisories from the US State Department, UK FCDO, and other government sources.
Mercosur (Mercado Común del Sur, or Common Market of the South) is South America's largest economic and political bloc. Full members are Argentina, Brazil, Paraguay, Uruguay, and Bolivia (which became a full member in July 2024). Venezuela is a member with suspended rights. Chile, Colombia, Ecuador, Guyana, Peru, and Suriname are associate members. Mercosur functions as a customs union with a common external tariff, free movement of goods and services within the bloc, and free movement of citizens using national ID cards. In December 2024, the EU and Mercosur announced political conclusion of a landmark trade agreement negotiated over 25 years; ratification is ongoing.
The Falkland Islands (called Islas Malvinas in Spanish) are a British Overseas Territory in the South Atlantic, approximately 500 km off Argentina's Patagonian coast. The UK has administered the islands continuously since 1833; Argentina claims sovereignty on the basis of geographic proximity, prior Spanish territorial claim, and 19th-century Argentine settlement predating the British takeover. The dispute led to the Falklands War in April to June 1982, in which Argentina briefly occupied the islands before UK forces retook them.
