We embark on our 3-day desert crossing. We spend three days in the stunning landscapes between the Salar de Uyuni and the Atacama Desert (Chile), exploring by four-wheel-drive vehicles. Driving across the salt flats is a fantastic experience, particularly for the contrast of piercing blue skies and blinding white salt on the flat lakebed. The area’s unusual landscape of mountains, active volcanoes, and geysers is like nowhere on earth.Twice submerged by a large, high-altitude lake, the salt flats now cover a total area of over 12000 square km (7440 square miles) and are one of the country’s main salt mining centres. The last large lake dried up about 8000 years ago, leaving the small lakes of Poopó and Ururu, as well as the salt flats of Uyuni.
