Salar de Uyuni is the world's largest salt flat at 10,582 square kilometers. It is located in southwestern Bolivia, and is elevated 3,656 meters above mean sea level. The Salar was formed as a result of transformations between several prehistoric lakes. It is covered by a few meters of salt crust, which has an extraordinary flatness with the average altitude variations within one meter over the entire area of the Salar. This place looks so surreal, it would be so cool to visit it! Thanks to Perfecta who went to Bolivia!
