What is the biggest mountain range in South America?

The Andes is recognized as the biggest mountain range in South America, extending over 7,000 kilometers (approximately 4,300 miles) along the western edge of the continent. This extensive range passes through several countries, including Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina. The Andes is not only significant due to its size but also because it hosts some of the highest peaks in the world, such as Aconcagua, which stands at 6,961 meters (22,838 feet) above sea level, making it the tallest mountain in South America.

Other mountain ranges listed, like the Rocky Mountains, Himalayas, and Alps, are located in different parts of the world. The Rockies are primarily found in North America, the Himalayas span across Asia with peaks like Mount Everest, and the Alps are situated in Europe. Each of these ranges has its own unique characteristics and height, but none approaches the length or geographical influence of the Andes in South America. This makes the Andes not only the largest mountain range in that region but also a significant geographical and cultural feature of the continent.
