Colca Canyon

Six hours north of Arequipa is the Colca Canyon - twice as deep as the
Grand Canyon, but almost an afterthought on the tour circuit. I spent
three days walking from the rim to the base of the canyon (and back),
stopping to view a family of massive condors, swim in natural hot
springs, eat cuy (roasted guinea pigs) in a small village, and watch a
woman check her llama in the luggage compartment under the bus back to
Arequipa.
