Holding the notable distinction of being the deepest canyon on earth, to say that hiking Cotahuasi is a formidable task is an understatement. This 3,535 meter valley (at its deepest spot) runs between the Coropuna and Solimana mountains, carved by the Rio Cotahuasi approximately 100 miles (161 km) northwest of Arequipa. Known for its incredible panoramic views, it's best to set aside 5 - 7 days to trek through this amazing natural wonder, which also offers incredible but insanely challenging white water rafting for skilled adventure seekers.
Location:100 miles (161 km) northwest of Arequipa, Peru
Note:Cotahuasi Canyon's main attraction, the Sipia Waterfall, is centrally situated in the Reserve, an approximately 7 hr. round-trip hike from Cotahuasi village.
