The Colca Canyon is a canyon of the Colca River in southern Peru, located about 160 kilometres northwest of Arequipa. With a depth of 3,270 metres, it is one of the deepest canyons in the world. Its length is about 70 kilometres. The Colca Valley is a colorful Andean valley with pre-Inca roots, and towns founded in Spanish colonial times, still inhabited by people of the Collagua and the Cabana cultures. The local people maintain their ancestral traditions and continue to cultivate the pre-Inca stepped terraces, called andenes.
It is Peru's third most-visited tourist destination with about 120,000 visitors annually.
