Cañón del Colca It’s deep, very deep, but the Colca Canyon is about far more than mere statistics. In an area colonized by pre-Inca, Inca and Spanish civilizations, the culture here is as alluring as the endless trekking possibilities. Stretching 100km from end to end and plunging over 3400m at its deepest part, the canyon has been embellished with terraced agricultural fields, pastoral villages, Spanish colonial churches and ruins that date back to pre-Inca times. Hike it, bike it, raft it or zip-line it – just keep your eyes peeled for the emblematic condors.
