Major Mountain Ranges of South America

South America, the fourth largest continent, harbors some of the world’s most imposing mountains. No other continent is dominated by mountains like South America.

The continent’s most dominant geographical feature are the Andes Mountains, which stretch along the western coast of South America. This mountain range is the highest range outside of the Himalayas. There are 100 peaks exceeding 6,000 meters (19,685 feet) in elevation here.

The Andes shapes the continent’s landscape, climate, and ecosystems to a significant extent.

The western slopes, facing the Pacific Ocean, receive heavy rainfall, fostering lush forests and fertile valleys, such as the renowned Sacred Valley in Peru and the fertile wine regions of Chile. Meanwhile, the eastern slopes experience a drier climate due to the rain shadow effect, leading to arid landscapes like the Altiplano, a high plateau spanning parts of Bolivia and Peru.

Andes Mountains

The Andes Mountains were created over 50 million years ago, when the South American and Pacific tectonic plates collided. They form the world’s longest continental mountain range, spanning an astonishing length of nearly 5,600 miles and span seven South American nations: Ecuador, Argentina, Bolivia, Colombia, Chile, Peru, and Venezuela.

These mountains are categorized into three diverse regions—the Dry Andes, the Wet Andes, and the Tropical Andes. The towering apex of the entire range is Mount Aconcagua in Argentina, soaring to a staggering elevation of 22,837 feet. Alongside this iconic peak, others like Mount Mercedario, Mount Bonete, and Mount Ojos del Salado add to the Andes’ distinction as the continent’s longest mountain range.

Cordillera Occidental

The Cordillera Occidental, also known as the Western Cordillera, forms part of the Andes mountain system. Running parallel to the Pacific coastline, the range creates a natural border between Bolivia and Chile. Nevado Sajama, the highest peak in Bolivia at approximately 21,463 feet (6,542 meters), is one of the prominent volcanic summits in the range.
