Set high up at an altitude of 3,860 metres (12,660 feet) the deep blue waters of Lake Titicaca form the world's highest navigable lake. Set so close to the heavens this is a deeply spiritual place for the indigenous population of Peru as the founders of the Inca civilisation are believed to have risen from the waters of the lake.

With the rarified airs and expanse of calm blue water it's easy to see why this became a sacred place for the local people.

The lake and surrounds are still home to deeply traditional and fascinating cultures, the most striking of which are Uros Indians, who build and live on islands that they construct from reeds.
