The Salar De Uyuni is by far the biggest salt lake in the world wtih hot springs, a white deserts with colored lagoons
This 12,000 sq km (4680 sq mi) saltpan at an altitude of 3650m (11,970ft) was once part of a giant prehistoric lake (40,000 years ago). It's estimated to contain 10 billion tons of fine salt reserves and produces 19,700 tons per year, largely using traditional methods. Isla de Pescadores, in the middle of the saltpan, has spectacular stands of cactus and is home to a stranded colony of vizcachas (long-tailed rodents related to the chinchilla). The village of Uyini, southeast of the saltpan, is the best base for excursions. Northwest of Salar de Uyini is the Salar de Coipasa, on whose northern shore is a unique Chipaya Indian village. Residents of this village may be descendants of the lost Tiahuanaco civilization. If you travel this far off the beaten track, be sensitive to local culture; photography of people in this region is discouraged.
Driving across it is one of the weirdest and most fantastic experiences anywhere on the continent, specially during June and July, when the bright blue skies contrast with the blinding-white salt crust and in the rainy season they turn into a gigantic mirror.

El salar de Uyuni o de Tunupa es, con sus 12.000 km², el mayor desierto de sal del mundo. Está situado a unos 3.650 metros de altura en el Departamento de Potosí, en el Altiplano de Bolivia, sobre la Cordillera de los Andes. El área que hoy ocupa este desierto, estaba cubierta hace 40.000 años por el Lago Ballivián. El Salar de Coipasa y los lagos Poopó y Uru Uru también son vestigios de este gran lago prehistórico.
