Reflective Salt Flats in Bolivia

Amazing salt flats where the sky and ground merge into one to create dreamy landscapes. Salar de Uyuni is the world’s largest salt flat at 10,582 square km. This is not water, the ground is covered in a layer of salt crust so reflective, it perfectly mirrors the sky. 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.
