It crosses Caylloma province, four hours from the city of Arequipa.
Striking features of the valley include the archaeological legacy of the Collagua, the ancient inhabitants of the region, mysterious petroglyphs and caves with "colcas" or containers for storing grain. It is a perfect place for camping and hiking.
42 km (26 miles) from Chivay, the first town on the route, there is a natural viewing point from where tourists can watch the condors flying around the Coropuna and Ampato volcanoes.
Also from this spot, tourists can admire a certain area of the canyon with a depth of 4,160 metres (13,648 feet) at its lowest point, making it one of the deepest in Peru.
The various towns in the valley offer accommodation and traditional food, as well as beautiful handicrafts such as carpets, embroidered skirts and blouses with colourful designs, embossed tin decorations, candles and carved wooden items.
