The mountain range that runs along the eastern coast of South America is the Andes Mountains. Stretching over 7,000 kilometers, the Andes are among the longest mountain ranges in the world. They are renowned for their rich biodiversity, unique ecosystems, and significant cultural heritage, as they house many Indigenous peoples and ancient ruins. The mountains significantly influence the climate of the region and are home to numerous national parks, making them a focal point for both tourism and conservation efforts.
