Salar de Uyuni is the largest salt flat in the world, with an area of approximately 10,582 square kilometres (4,086 mi2). Sustainability has gained a critical concern as an increasing number of tourists head to Salar de Uyuni.

When it dried, it left behind two modern lakes, Poopó and Uru Uru, and two major salt deserts, Salar de Coipasa and the larger Salar de Uyuni. Uyuni originates from the Aymara language and means a pen (enclosure); Uyuni is also the name of a town that serves as a gateway for tourists visiting the Salar. The large area, clear skies, and exceptional flatness of the surface make the Salar ideal for calibrating the altimeters of Earth observation satellites. The Salar was formed as a result of transformations of seven Late Pleistocene lakes whose progressive desiccation led to the accumulation of extensive evaporitic salt deposits.

Laguna Verde (Green Lake) turns green when strong winds lift the sediments of arsenic, copper, lead, and other minerals from the bottom of the lake. To add to the experience, we could see flamingos at Laguna Challviri. On our 2025 tour, we practically had the place to ourselves and enjoyed it more, as there was only one other group besides us. Challviri Hot Springs are tucked away near Laguna Challviri and are much quieter and usually less visited. The water is about 29 degrees Celsius and contains minerals that relieve the symptoms of arthritis and rheumatism.
These months are also less cold than the dry season. Some would argue the vistas during the wet season are even more mesmerising than in the dry season. The rainy season (December to April) brings its own beauty.

Because of its location, large area, and flatness, the Salar is a major car transport route across the Bolivian Altiplano, except when seasonally covered with water.

Here’s all you need to know about this unique experience. The fields of salt, extending as far as the eye can see and backed by distant mountains, create one of the most dramatic and unique vistas on Earth. Salar de Uyuni is the remains of an enormous prehistoric lake. In February 2024, the Copernicus Sentinel-3B mission conducted calibration activities over the salar for its Synthetic Aperture Radar Altimeter (SRAL). As part of its validation strategy, CryoSat-2 has relied on the salar, where its Interferometric synthetic-aperture radars (InSAR) capabilities were reinstated to enhance the precision of altimetric observations. The mission focused on calibrating radar-based measurements of surface topography.
It is estimated to contain around 10 billion tonnes of salt! Salar de Uyuni sits at an altitude of 3,650 metres and covers a staggering 10,000 sq km. (There are no day buses for some reason.) Local buses can be booked on busbud.com.

Another popular option for travellers heading north from Chile is to take a tour from the border town of San Pedro de Atacama.
The structure of the salt crust (Polygons, fractures, micro-textures)
Most locals make their living from salt production. Drinks were provided with meals, usually water and Coke, and dinners often came with red wine. When we did a tour in 2025, we paid extra for private rooms. When I did a tour eight years ago, the accommodation was basic. The tour takes you through elevations ranging from about 3,600 m to 4,800 m.
