Lake Titicaca

Occupying a great swathe from Ecuador to Argentina, the vast Altiplano is the largest high plateau outside Tibet. One of the world's great rail journeys traverses the plateau from Cusco to Lake Titicaca which, at 4000m in altitude, is the world's highest navigable lake. Titicaca is home to alpacas, llamas and the Uros and Aymara peoples with a long history predating the Incas by thousands of years, many of whom still live on floating reed islands and travel by reed boat.
