mountain ranges in south america

On this page we explore the mountain ranges of South America.

From the vast Andes that span seven countries and run the full length of South America, to the coastal range of the Brazilian Serra do Mar and tropical rain forest of Suriname's Wilhelminagebergte.  

We also look at some of the most iconic mountain peaks on the continent, and best South American hikes.

South American Mountain Ranges

Although there are a number of notable mountain ranges in South America, none come close to the scale and vastness of the Andes. In fact most South American ranges are just sub-ranges of the Andes.

Below we take a brief look at the Andes and one of it's sub-ranges, Cordillera Blanc. We also provide a table of the main ranges in South America. 



The Andes is the longest continental mountain range in the World, around 7,000 km (4,300 miles) long. The range spans the full length of the western side of South America, passing through seven countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile and Argentina.

Outside of Asia, the Andes also has the highest mountains in the World - with 100 peaks exceeding 6,000m in elevation. Due to its sprawling length and breadth, the Andes is often categorised into three main climate zones: the tropical Andes, wet Andes and dry Andes. 

Apart from the incredibly diverse fauna and flora that is found in the Andes, and the amazing array of cultures that call the Andes home, here you can find some of the world's most beautiful mountains. They have a number of claims to fame;

For example, the Andes are home to Chimborazo, a mountain in the Ecuadorian Andes, which at its summit is the farthest point from the Earth's center - this is due to the equatorial bulge resulting from the Earth's rotation. Moreover, the World's highest volcanoes are in the Andes, including Ojos del Salado (6,893m / 22,615ft).

Cordillera Blanca


The Cordillera Blanca (in English: 'White Range') is a Peruvian mountain range that is part of the wider Andes. 

The range is around 200km (124 miles) long and is home to many 6000m peaks, including the highest mountain in Peru, Huascarán (6,768m / 22,205ft).

Notable South American Mountains

South America has a number of iconic mountain peaks. Here are a few South American mountains worthy of particular mention.



Aconcagua is the highest peak in South America and one of the 7 Summits.

Standing at 6,962m / 22,837 ft, Aconcagua is a serious challenge for any mountaineer. The Normal Route up Aconcagua is relatively non-technical, but high winds, inclement cold weather and high altitude make summiting Aconcagua a tough feat.

For more technical climbers, the Polish Glacier Traverse and Direct route are exciting options, albeit with lower summit success rates.



Alpamayo is an iconic peak in the Cordillera Blanca of the Peruvian Andes. Standing at 5,947 m (19,511 ft), Alpamayo was once voted the "Most Beautiful Mountain In The World" by Alpinismus, a German mountaineering magazine.



Cotapaxi is an active stratovolcano situated in Ecuador. Standing at 5,897 m (19,347 ft) it is the second highest mountain in Ecuador and one of the highest volcanoes in the World.
