They travel around and between islands on these cool reed boats that take like 3 months to build and then last for about a year before they disintegrate.
The Colca Canyon. Aparently the second deepest canyon in the world at just over 3000m! But how do you measure it? Obviously from the top of the highest mountain to the bottom. We did a walk down to the bottom of the canyon from a town and only had to drop down 1200m. Still it is an amazing place and the canyon is big enough.
The Nazca Lines. Got a good deal, did the 30min flight. These lines were made 100's of years ago before planes existed, and are one of the worlds great misteries as to why and how they were made - when there true form can only be seen and apreciated from the air (they are massive).
