They traverse seven countries from north to south: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina.
The range includes numerous peaks over 6,000 meters, with Aconcagua (6,961 m / 22,838 ft) in Argentina being the highest outside Asia. The Andes shape the continent's climate, biodiversity, and human settlement patterns, hosting unique ecosystems from tropical cloud forests to high-altitude altiplano deserts.
