It is located north of the city of Arequipa, at 180 km (111.8 miles) from it. Over this valley, the erosion from the Colca River creates a canyon of about 70 km. (43.5 miles) length, being the deepest of the world, 3000 meters (9,842 feet). Very beautiful landscapes with strong wind, over flight by condors which are the biggest birds in the world.

In the mirador "Cruz del Condor" located among Maca and Cabanaconde's town (place of privileged view), is very common to see condors in majestic flight.
