This magnificent lake, the largest in South America, ripples at 3,810m altitude (2,367mi) high in the Andes Mountains. Offering a picturesque view of towering peaks reflected in cobalt waters, it is also the highest navigable body of water in the world. However, it is so much more than these simple facts. Once the cradle of Andean civilisation, the Incans believed it to be their birth place, and the place to which their spirits would return after life. Today, it continues to hold a sacred space for many of the indigenous farming tribes, descendants of which can still be found in the region, who eke out an existence along the banks or islands of the lake.
