The beautiful Uyuni salt flats are the world’s largest salt flat. It is located in the Department of Potosi in Southwest Bolivia at 3.650 meters above sea level. Some 40.000 years ago, the area was part of Lake Minchin, a giant prehistoric lake. When the lake dried up, it left behind two modern lakes, Poopó and Uru Uru, and two major salt deserts: Salar de Coipasa and the larger Salar de Uyuni. The Uyuni Salt Flats are roughly 25 times the size of Bonneville Salt Flats in the United States! La Isla del Pescado (Fish Island), which is located on the salt flat, is full of giant cactuses and named this way as the ´island´ has the shape of a fish. It is the only sign of life for miles.
