This canyon is reportedly the deepest in the world, thought to be twice as deep as the Grand Canyon in the USA. Unlike most of the Grand Canyon, portions of the Colca canyon are habitable, with pre-Colombian terraced fields still supporting agriculture and human life.

A highlight of the Colca Canyon is a stop at Cruz del Condor, the pass where condors soar gracefully on the rising thermals occurring as the air warms. You'll want to be there early to see the condors in flight. They hunt in the morning or late afternoon and watching them is an unforgettable experience. There are no railings, and the floor of the canyon is 3960 ft (1200m) below the viewing area, so please watch your step.
