South America contains some of the most dramatic mountain landscapes on Earth. The continent’s western edge is dominated by the immense Andes Mountains, while older highlands, forested coastal ranges, isolated massifs, and flat-topped tepuis rise across Colombia, Venezuela, Guyana, Suriname, French Guiana, and Brazil.
The Andes are not a single unbroken ridge. They form an enormous mountain system divided into hundreds of individual cordilleras, volcanic chains, plateaus, valleys, and massifs. Beyond the Andes, the continent also includes the ancient Guiana Highlands and the ranges of the Brazilian Highlands.
This guide explores the major mountain ranges in South America, their highest peaks, geography, geology, ecosystems, and most famous destinations.

Some names in this table describe subdivisions of the Andes, while others refer to broader mountain regions containing several individual ranges.
🏔️ The Andes Mountains
The Andes Mountains, or Cordillera de los Andes, form the mountainous backbone of South America. They extend for more than 7,000 kilometers along the western side of the continent, from the Caribbean coast of Venezuela and Colombia to Patagonia and Tierra del Fuego.
The Andes pass through seven countries:
- Venezuela
- Colombia
- Ecuador
- Peru
- Bolivia
- Chile
- Argentina
They contain the highest mountains outside Asia, including Aconcagua, officially measured at 6,960.8 meters. The range also includes Ojos del Salado, the world’s highest volcano, and dozens of additional summits exceeding 6,000 meters.
The enormous system is generally divided into the Northern Andes, Central Andes, and Southern Andes. Each region has its own geology, climate, ecosystems, and characteristic mountain scenery. (USGS)
Readers can explore the system visually in the Map of the Andes Mountain Range.
🌿 The Northern Andes
The Northern Andes extend across Venezuela, Colombia, and Ecuador. Tropical conditions, heavy rainfall, active volcanoes, cloud forests, páramo grasslands, fertile valleys, and deeply eroded ridges distinguish this region from the colder and drier Central Andes.
Unlike the simpler mountain alignment seen farther south, the Andes divide into several branches in Colombia and Venezuela.
Cordillera de MĂ©rida
The Cordillera de MĂ©rida forms the principal Andean chain in western Venezuela. It rises between the lowlands surrounding Lake Maracaibo and the Llanos.
Its highest summit is Pico BolĂvar, approximately 4,978 meters above sea level. Other notable mountains include Pico Humboldt, Pico Bonpland, and Pico La Concha.
Although Venezuela’s tropical glaciers have almost disappeared, the range still contains steep alpine terrain, glacially carved valleys, high páramo ecosystems, and cool mountain communities.
Colombia’s Three Andean Cordilleras
The Andes enter southwestern Colombia as a single mountainous region before separating into three major branches:
Cordillera Occidental
The Cordillera Occidental is the westernmost and generally lowest of Colombia’s three principal Andean chains. It lies close to the Pacific coast and includes heavily forested slopes receiving some of the highest rainfall totals in the world.
Cordillera Central
The Cordillera Central contains many of Colombia’s highest volcanoes, including Nevado del Huila, Nevado del Ruiz, Nevado del Tolima, and Nevado del QuindĂo.
The Cauca Valley separates it from the Cordillera Occidental, while the Magdalena Valley lies between the Central and Eastern cordilleras.
Cordillera Oriental
The Cordillera Oriental is the widest of Colombia’s three Andean branches. It contains the Bogotá Plateau, the Sierra Nevada del Cocuy, high páramo landscapes, and the headwaters of several important rivers.
The three Colombian cordilleras are separated principally by the Cauca and Magdalena river valleys. (Colombia Travel)
Sierra Nevada de Santa Marta
The Sierra Nevada de Santa Marta rises independently from the Caribbean coast of northern Colombia. Although it stands near the northern Andes, it is geologically separate from the three main Colombian cordilleras.
Its highest summits are Pico CristĂłbal ColĂłn and Pico SimĂłn BolĂvar. Published elevations vary, but both peaks rise to approximately 5,700 meters, only a short distance from the Caribbean Sea.
This extraordinary elevation change creates environments ranging from tropical coastal forest to cloud forest, páramo, rock, and formerly extensive glacial terrain. The mountains are also the ancestral homeland of the Kogui, Arhuaco, Wiwa, and Kankuamo peoples.
Because survey measurements differ, precise elevations for the two highest summits should be treated cautiously. Colombian park authorities have traditionally listed them at 5,775 meters, while satellite-derived measurements generally indicate lower figures. (UNESCO)
Ecuadorian Andes
Ecuador’s Andes consist of two roughly parallel chains separated by a central intermontane valley. The region is famous for its chain of enormous volcanoes, sometimes called the Avenue of the Volcanoes.
Important Ecuadorian mountains include:
- Chimborazo
- Cotopaxi
- Cayambe
- Antisana
- El Altar
- Sangay
- Tungurahua
Chimborazo is Ecuador’s highest mountain. Because Earth bulges around the equator, its summit is also the point on Earth’s surface farthest from the planet’s center, although Mount Everest remains higher above sea level. (Ecuador Travel)
🏔️ The Central Andes
The Central Andes extend primarily across Peru and Bolivia, with adjoining sections in northern Chile and northwestern Argentina. This is the widest part of the Andean system and includes vast high plateaus, enormous volcanoes, salt flats, glaciated cordilleras, and some of the continent’s highest peaks.
Cordillera Blanca
Peru’s Cordillera Blanca is the highest tropical mountain range in the world. It rises in the Ancash Region of north-central Peru and contains a remarkable concentration of glaciers and summits above 6,000 meters.
Its highest mountain is Huascarán, which reaches 6,768 meters and is the highest point in Peru.
Other major Cordillera Blanca peaks include:
- Huandoy
- Chopicalqui
- Huantsán
- Alpamayo
- Artesonraju
- Chacraraju
- Hualcán
Much of the range lies within Huascarán National Park, a UNESCO World Heritage Site. Its turquoise glacial lakes, high valleys, ice-covered summits, and well-developed trekking routes make it one of South America’s most important mountain destinations. (UNESCO World Heritage Centre)
Cordillera Huayhuash
South of the Cordillera Blanca lies the smaller but exceptionally rugged Cordillera Huayhuash. Its highest mountain is Yerupajá, Peru’s second-highest summit at approximately 6,635 meters.
The range also contains:
- Siula Grande
- Jirishanca
- Sarapo
- Rasac
- Rondoy
- Trapecio
The Cordillera Huayhuash Circuit is frequently regarded as one of the world’s finest high-altitude treks. It passes beneath enormous ice-covered walls and crosses multiple passes above 4,500 meters.
Despite its relatively compact size, the Huayhuash contains some of the most technically difficult mountains in the Andes.
Cordillera Vilcabamba
The Cordillera Vilcabamba rises northwest of Cusco in southern Peru. It is best known for the mountains and cloud forests surrounding Machu Picchu.
Its highest summit is Salcantay, approximately 6,271 meters. Other notable peaks include Humantay, Pumasillo, and Veronica.
The range marks a dramatic transition between the high Andes and the upper Amazon Basin. Moist air from the east supports cloud forests on its lower slopes, while glaciers and alpine terrain occupy the highest elevations.
Cordillera Real
The Cordillera Real rises east of Bolivia’s Altiplano, forming a spectacular wall of glaciers and sharp peaks above the cities of La Paz and El Alto.
Major summits include:
- Illimani
- Ancohuma
- Illampu
- Huayna PotosĂ
- Condoriri
- Chachacomani
Illimani, approximately 6,438 meters high, is the best-known mountain in the range and an unmistakable landmark from La Paz.
The Cordillera Real forms part of the Cordillera Oriental of Bolivia. Its eastern slopes descend rapidly toward the humid Yungas and the upper Amazon Basin.
Cordillera Occidental
The Cordillera Occidental follows the western side of the Peruvian and Bolivian Andes and continues into Chile. It contains numerous volcanoes, desert plateaus, salt flats, and high-altitude lakes.
The Cordillera Occidental of Bolivia includes Sajama, Bolivia’s highest mountain, as well as Parinacota, Pomerape, and Licancabur.
Farther south, the chain merges into the volcanic mountains of the Atacama region. Ojos del Salado rises along the Chile–Argentina border to 6,893 meters, making it the second-highest mountain in South America and the highest volcano on Earth. (Ejército de Chile)
🏜️ The Altiplano and Andean Plateaus
The Altiplano is not a conventional mountain range, but it is one of the defining geographical features of the Central Andes.
This vast high plateau lies between the eastern and western Andean cordilleras, principally in Bolivia and Peru, with extensions into Chile and Argentina. Much of it stands between 3,500 and 4,500 meters above sea level.
Major features include:
- Lake Titicaca
- Salar de Uyuni
- Salar de Coipasa
- Volcanic fields
- High puna grasslands
- Desert basins
- Wetlands inhabited by flamingos and vicuñas
The Altiplano is often described as the world’s most extensive high plateau outside Tibet. It also contains major population centers, including La Paz, El Alto, Oruro, and Puno.
🏔️ The Southern Andes
The Southern Andes extend through Chile and Argentina. They include the continent’s highest summit, some of its driest high mountains, temperate forests, enormous ice fields, volcanic chains, granite massifs, and deeply cut Patagonian fjords.
Principal Cordillera
The Principal Cordillera forms much of the high Andes along the Chile–Argentina border. It contains Aconcagua, the highest mountain in the Americas, Southern Hemisphere, and Western Hemisphere.
Aconcagua’s officially measured elevation is 6,960.8 meters. Although it is not an active volcano, much of the surrounding region consists of volcanic and sedimentary rock uplifted during the development of the Andes.
Other major peaks in or near the Principal Cordillera include:
- Tupungato
- Cerro El Plomo
- Cerro Juncal
- Maipo
- San José
- Marmolejo
Cordillera Frontal
The Cordillera Frontal runs mainly through western Argentina, east of the Principal Cordillera. It contains high, dry mountains with broad valleys and extensive fields of broken rock.
Major massifs include:
- CordĂłn del Plata
- Cordillera de la Ramada
- Cordillera Ansilta
- Cordillera del Tigre
Cerro Mercedario, rising to approximately 6,720 meters in the Cordillera de la Ramada, is one of the highest mountains in Argentina.
Precordillera
The Precordillera forms a lower set of ranges east of the high Andes in Argentina. It extends mainly through La Rioja, San Juan, and Mendoza provinces.
These mountains are generally drier and lower than the main Andes, but they contain dramatic folded rock formations, desert valleys, archaeological sites, and important fossil deposits.
The Principal Cordillera, Cordillera Frontal, and Precordillera form three distinct relief units in western Argentina.
Patagonian Andes
South of the high, dry central ranges, the Andes enter Patagonia and become lower, wetter, more heavily glaciated, and increasingly fragmented.
The Patagonian Andes extend across southern Chile and Argentina. They contain temperate rainforests, volcanoes, fjords, glacial lakes, and extensive ice fields.
Famous regions include:
- Bariloche and Nahuel Huapi
- Los Glaciares National Park
- Northern and Southern Patagonian Ice Fields
- Fitz Roy massif
- Cerro Torre
- Torres del Paine
- Mount San ValentĂn
- Mount Fitz Roy
- Cerro Castillo
Granite towers such as Fitz Roy and Cerro Torre are much lower than the 6,000-meter giants farther north, but their steep walls, severe weather, and heavily glaciated terrain make them exceptionally difficult climbing objectives.
Cordillera Darwin
The Cordillera Darwin occupies the southwestern portion of Tierra del Fuego in Chile. It is one of the most remote and least accessible mountain ranges in South America.
The range contains:
- Jagged peaks
- Extensive glaciers
- Subpolar forests
- Deep fjords
- Channels connecting the Pacific and Atlantic regions
Much of the Cordillera Darwin lies within Alberto de Agostini National Park. The landscape is strongly shaped by glaciation, heavy precipitation, powerful winds, and its maritime climate. (Conaf)
🪨 The Guiana Highlands
The Guiana Highlands rise north of the Amazon Basin across parts of Venezuela, Guyana, northern Brazil, Suriname, French Guiana, and southeastern Colombia.
These highlands are geologically much older than the Andes. Rather than forming through recent subduction and mountain building, they are part of the ancient Guiana Shield.
Their most famous landforms are tepuis—isolated, flat-topped mountains surrounded by immense cliffs.
Pakaraima Mountains
The Pakaraima Mountains extend across Venezuela, Guyana, and northern Brazil. Their best-known summit is Mount Roraima, a giant tepui rising near the meeting point of the three countries.
Roraima’s broad summit plateau contains unusual rock formations, pools, waterfalls, and plant species adapted to its wet and nutrient-poor environment.
Other important tepuis and massifs include:
- Auyán-tepui
- Kukenán-tepui
- Chimantá Massif
- Neblina Massif
- Marahuaca
- Duida
Angel Falls descends from Auyán-tepui in Venezuela’s Canaima National Park. UNESCO reports that more than 100 flat-topped mountains occur within the park’s Guiana Highlands landscape. (UNESCO)
Wilhelmina Mountains
The Wilhelmina Mountains rise within the forested interior of Suriname. They form part of the wider Guiana Highlands and contain remote ridges, granite outcrops, waterfalls, and largely undisturbed tropical rainforest.
Unlike the open alpine landscapes of the Andes, many mountains in the Guianas are covered in dense forest and remain difficult to reach.
Pico da Neblina and the Serra do Imeri
Pico da Neblina, Brazil’s highest mountain, rises in the Serra do Imeri near the Brazil–Venezuela border. Its elevation is approximately 2,995 meters.
Although modest compared with the Andes, Pico da Neblina stands above an immense area of tropical rainforest. Access is controlled, and expeditions generally require authorization and coordination with Indigenous communities. (AgĂŞncia de NotĂcias IBGE)
🌳 The Brazilian Highlands
The Brazilian Highlands cover a large part of central, eastern, and southeastern Brazil. They are not one continuous mountain chain but a broad region of plateaus, escarpments, ridges, and isolated ranges.
Unlike the geologically young Andes, many Brazilian ranges consist of ancient rock shaped by long periods of erosion.
Serra do Mar
The Serra do Mar runs roughly parallel to Brazil’s southeastern Atlantic coast. It forms a steep escarpment separating coastal lowlands from the inland plateau.
The range passes through or near several states, including:
- Rio de Janeiro
- SĂŁo Paulo
- Paraná
- Santa Catarina
Its slopes support remnants of the Atlantic Forest, one of the world’s most biologically diverse and threatened forest regions.
The Serra do Mar also influences rainfall. Moist Atlantic air rises over the escarpment, producing heavy precipitation on seaward slopes. (UNESCO World Heritage Centre)
Serra da Mantiqueira
The Mantiqueira Mountains rise inland from the Serra do Mar across parts of Minas Gerais, Rio de Janeiro, and SĂŁo Paulo.
The range contains several of southeastern Brazil’s highest mountains, including:
- Pedra da Mina
- Pico das Agulhas Negras
- Morro do Couto
- Prateleiras
Pedra da Mina reaches approximately 2,798 meters and is Brazil’s fourth-highest officially measured summit. The Serra Fina Traverse and the high country of Itatiaia National Park are among the region’s best-known hiking areas. (AgĂŞncia de NotĂcias IBGE)
Serra do Espinhaço
The Serra do Espinhaço extends through Minas Gerais and Bahia. Its quartzite ridges, rocky grasslands, canyons, waterfalls, and high level of plant endemism distinguish it from Brazil’s forested coastal mountains.
Important sections include:
- Serra do CipĂł
- Chapada Diamantina
- Serra do Caraça
- Serra do Cabral
The range functions as an important watershed between rivers flowing toward the SĂŁo Francisco basin and those reaching the Atlantic Ocean.
Serra Geral
The Serra Geral forms a series of escarpments and highlands in southern Brazil. It is associated with enormous basalt lava flows that covered parts of South America during the breakup of Gondwana.
Its landscape includes:
- Deep canyons
- Grass-covered plateaus
- Araucaria forests
- Waterfalls
- Sheer basalt cliffs
Aparados da Serra and Serra Geral national parks protect some of its most dramatic scenery.
🪨 How South America’s Mountain Ranges Formed
South America’s mountain landscapes represent several very different geological histories.
Formation of the Andes
The Andes developed primarily through the convergence of oceanic and continental tectonic plates. The Nazca Plate is being forced beneath the South American Plate along much of the continent’s Pacific margin.
This subduction has produced:
- Crustal compression
- Folding and faulting
- Regional uplift
- Earthquakes
- Magma generation
- Long chains of volcanoes
The process remains active, which is why western South America experiences frequent earthquakes and volcanic eruptions. (USGS)
Formation of the Guiana and Brazilian Highlands
The Guiana and Brazilian shields consist largely of ancient Precambrian rock. These areas are far older and more tectonically stable than the Andes.
Their modern mountains were shaped mainly by:
- Long-term erosion
- River incision
- Weathering
- Faulting
- Uplift of plateaus and escarpments
The distinctive tepuis of the Guiana Highlands are remnants of ancient sandstone plateaus that were gradually separated by erosion.
🌿 Mountain Ecosystems of South America
The enormous north-to-south extent and elevation range of South America’s mountains create exceptional ecological diversity.
Tropical Cloud Forests
Moist lower slopes in Colombia, Ecuador, Peru, Bolivia, Venezuela, and Brazil support cloud forests filled with mosses, orchids, bromeliads, ferns, birds, amphibians, and insects.
Páramo
Páramo occurs above the forest line in the tropical Northern Andes, particularly in Venezuela, Colombia, and Ecuador.
These cool, wet grasslands contain highly specialized plants and store large quantities of water that feed rivers and urban water systems.
Puna and Altiplano
The Central Andes contain drier puna grasslands and shrublands. Typical wildlife includes:
- Vicuñas
- Guanacos
- Andean foxes
- Viscachas
- Flamingos
- Andean condors
Andean Deserts
The western Central Andes include some of the driest mountain landscapes on Earth. High volcanoes rise above salt flats, gravel plains, frozen ground, and the Atacama Desert.
Patagonian Forests
The lower Patagonian Andes support temperate forests dominated by southern beech species. Rainfall is especially heavy on western slopes, while the eastern side lies within a strong rain shadow.
Atlantic Forest
Brazil’s Serra do Mar and Serra da Mantiqueira protect important fragments of Atlantic Forest. These mountain forests contain high numbers of endemic plants, birds, mammals, amphibians, and insects.
