Location

Cotahuasi is located at the highest Andean point of Arequipa, in the south of Peru : UTM 683,370 & 790,415 East & 8’275,582 & 8’380,125 North. Between 14°40´22" & 15°35´27" south latitude, 72°19´15" & 73°18´08" west longitude. This province is characterized by its steep relief: incised by rivers and gullies, ranging between 1,000 and 6,093 metres, with 19 ecological zones. As is the case with cultures all over the world, the people of highland Arequipa Province are also changing with the times. Nonetheless, the altitude and remoteness of this region mean that residents have retained many of the practices that are now no longer common in neighboring regions.


Access

The only road leading to the canyon goes through Chuquibamba in the Condesuyos province, then Aplao in Castilla Province. It begins on the

near Arequipa. Four bus companies start daily from the Arequipa bus terminal, between 4 and 6 pm. The bus drive is 10–12 hours long, on a road which is unpaved after Chuquibamba. It also goes quite high, through a 4500m pass between Coropuna and Solimana.


Protected area

The Cotahuasi Subbasin is a landscape park set up by a 2005 decree. It covers . This natural reserve preserves an integrated environment where man and nature are living in close harmony, in a preserved cultural microcosm. The difficult topographic conditions have generated specific landscapes like agricultural terraces.
