Due to lack of conventional construction materials, many of them are almost entirely (walls, roof, furniture) built with salt blocks cut from the Salar. Salar de Uyuni is estimated to contain 10 billion tonnes (9.8 billion long tons; 11 billion short tons) of salt, of which less than 25,000 t is extracted annually. Lithium is concentrated in the brine under the salt crust at a relatively high concentration of about 0.3%. The brine is a saturated solution of sodium chloride, lithium chloride, and magnesium chloride in water. During the wet season, Titicaca overflows and discharges into Poopó, which in turn, floods Salar De Coipasa and Salar de Uyuni.

Because of this, NASA and ESA regularly use Salar de Uyuni to calibrate satellite altimeters—something only this kind of surface can offer.
Laguna Honda
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.

That’s what it’s like when you visit the Salar de Uyuni, Bolivia’s enormous salt flat that stretches as far as your eyes can see. Alternatively, shorter one- to three-day tours are available from Uyuni or Tupiza, depending on your onward travel plans. Travellers with more time can opt for extended five- or nine-day tours from Salta, Argentina. From December to April, the wet season creates a stunning mirror effect across the salt flats.
Now one of the key stops on Salar de Uyuni tours, it’s become something of a tourist trap. The area was once covered by a huge saltwater lake, which dried up some 30,000–40,000 years ago. The focal point of any Salar de Uyuni tour is, of course, the world’s largest salt flat. Known locally as Salar de Uyuni, the salt flats are part of the Altiplano, a vast plateau that extends for 965 km from southern Peru to the southwestern corner of Bolivia. As the largest salt flat on Earth, the Salar de Uyuni is widely regarded as one of the most effective natural calibration sites for Earth-observing satellites. Multiple fatal incidents have occurred at the salt flat as a result of poorly maintained vehicles, untrained drivers, speeding, a disregard for the inhospitable conditions, and lack of regulation for tour companies.
Some tours include an overnight stay near the salt flats, while others return to Uyuni the same day. Three- and four-day tours to the salt flats operate from here, and booking a guided tour is strongly recommended, as crossing the border independently can be challenging. When visiting the breathtaking salt flats, consider enhancing your experience by staying at a hotel made entirely of salt.
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.
