On Day 2 in Arequipa we started a 2 day tour of the Colca Valley. Turns out the region is pretty interesting geologically with volcanoes, canyons they claim to be deeper than the Grand Canyon (true, but not as steep or impressive), valleys with cinder cones, etc. etc. We decided on the Colca Valley tour because we only had a couple days and couldn't do everything.
