Colca Canyon (Cañón del Colca) is carved by the Colca River in southern Peru, about 160 km (99 mi) northwest of Arequipa in the Caylloma Province. At ~3,270 m (10,730 ft) deep, it ranks among the world's deepest canyons—more than twice the depth of the Grand Canyon.
The area is renowned for Andean condor sightings, traditional villages, terraced agriculture, and hot springs.
