The Colca Canyon, located in the Caylloma province, is more than 100 km long. It starts to deepen a few kilometres past Chivay and is considered to be one of the deepest in the world. The Colca area is perfect for adventure tourism such as rafting, kayaking, and trekking. The road joining the city of Arequipa to the Colca Valley crosses the Pampa Cañahua, a natural reserve which protects the most valuable of all South American cameloids, the vicuña (Vicugna vicugna), which produces the finest and most sought after wool in the international market.
The region of Colca boasts an important diversity of species of fauna such as the American Kestrel (Falco sparverius), the Peregrine Falcon (Falco peregrinus), the Andean Tinamou (Northroprocta pentlandii), the Puma (Puma concolor) and the four species of South American cameloids, the Vicuña and the Guanaco (which are wild) and the Llama and Alpaca which have been domesticated. Among the species of plants, the most representative of the area are Ichu, Tola and Yareta.
The Colca Canyon is located along a valley of the same name. Its depth reaches 3'180 meters, making it a wonder worth admiring.
