One of the deepest canyons on the planet, twice as deep as the Grand Canyon. But you don't come to Colca just for the abyss: you come for the condors. At dawn, from the Cruz del Cóndor lookout, these enormous birds take off and glide centimeters from your head, riding the air currents. Below, Inca farming terraces and villages where time stood still. A spectacle of nature that's hard to match.
