Salar de Uyuni is one of the most extraordinary destinations on the planet. This 9,000 km² (4,680 sq mi) salt desert, located at an elevation of 3,650 meters (11,970 feet) above sea level, is the largest salt flat in the world. This surreal landscape stretches to the horizon in every direction, creating a natural mirror during the rainy season and a dazzling white expanse during the dry season.
This stunning geological wonder was once part of a prehistoric salt lake that covered most of southwestern Bolivia. Over time, the lake evaporated, leaving behind a thick crust of salt. Today, this crust covers an estimated 10 billion tons of fine salt. Local campesinos continue to harvest it using only picks and shovels, preserving traditional techniques in a place that feels like another world.
Travelers exploring Salar de Uyuni are captivated by the stark beauty and unusual silence of this remote region. Its seemingly endless white plains make it a dream for photographers and adventurers alike. Situated in a semi-arid climate, Salar de Uyuni receives only about 10 inches of rainfall annually. This means the landscape transforms dramatically between seasons.

How to Get to Salar De Uyuni

Most travelers come from La Paz or Sucre by overnight bus, which is the most budget-friendly option, or by a short domestic flight from La Paz if you prefer something faster and more comfortable. You can also enter from San Pedro de Atacama in Chile through a multi-day tour that crosses the border into Bolivia.
Once you’re in Uyuni, you’ll join a guided tour, as independent visits aren’t common. If you’re short on time, a 1-day salt flat tour covers the main highlights. A 2-day tour usually includes the salt flats and nearby volcanoes. In contrast, a 3-day Altiplano tour takes you further into the desert landscapes, lagoons, and high-altitude scenery for a more complete experience.
