3. Uyuni Desert (Bolivia), the world's largest salt-lake desert
Uyuni Desert is located in the tableland of southern Bolivia, covers an area of 12,000 square kilometers and is 250 kilometers long by 150 kilometers wide.
As the world's largest salt lake, Uyuni has 65 billion tons of salt, with many salt beds spanning more than 10 meters. The surface of the lake reflects the sun's light like a mirror, and the body of the lake is colorful because of the mineral deposits at the bottom. But with an altitude of 3,700 meters and 10,000 square kilometers of uninhabited lake area, it can be difficult to reach it.
