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.
When the rain accumulates on the layer of salt, Salar de Uyuni is transformed into a tremendous mirror and reflects the clouds, sunrises and sunsets flawlessly. The skies are very clear and can be viewed without clouds to have a perfect view of the stars and also photography. It presents the most opportune moment to the travelers that wish to go exploring in 4×4 vehicles and see the islands that are found in the flats. A land of the opposites – it is where the geological formations of the past are in contact with the futuristic sceneries that have been a source of inspiration to filmmakers, photographers and even adventurers. Salar de Uyuni is not just a vast expanse of salt, but it is located in southwest Bolivia, almost on the crest of the Andes, some 3,656 meters above sea level.
- However, if you are travelling from La Paz (which is at a similar altitude) or Cusco (just 250 m lower) then you will likely be fine as you should have acclimatised.

- You’ll follow the same itinerary as the first day of the 2-day and 3-day tours.
- Catch a local bus to Colchani (this is a stop on tours to visit a salt museum).
- The ideal time for stargazing is during the dry season (April to November) and particularly around new moon phases, when the skies are clear and dark.
- These months are also less cold than the dry season.
- The salt flats are at 3,656 m.a.s.l. Some people can suffer from altitude sickness at this elevation.

We chose a Spanish-speaking tour, and our basic Spanish was more than enough. It’s worth mentioning that you will spend most of your time in the car. So, below are a few points to know before choosing a tour. I recommend booking in person, as it’s usually cheaper.
Welcome to Offseason Travel
A unique geological feature characterised by small, eye-like holes in the salt flats. Walking across the salt flats allows you to truly appreciate the scale of the landscape and feel the texture of the salt crust underfoot. The Salar de Uyuni in Bolivia offers a variety of activities, from exploring its vast salt flats to discovering the surrounding lagoons and volcanoes. The salt flats, visible from low Earth orbit, display stark white hues that contrast sharply with the darker surrounding rock formations. For much of the year, the salt flats stretch out in a seemingly endless expanse of white, covering about 10,000 square kilometers (4,000 square miles). The salt flat was formed through the gradual evaporation of prehistoric lakes, leaving behind an extensive, flat salt crust.
Salar de Uyuni spreads over 10,582 km2, which is roughly 100 times the size of the Bonneville Salt Flats in the United States. The youngest prehistoric lake was Coipasa, which was radiocarbon dated to 11,500 to 13,400 spinmaya no deposit bonus code years ago. Some 30,000 to 42,000 years ago, the area was part of a giant prehistoric lake, Lake Minchin.
Make sure you know what the weather will be like before you book a tour and therefore what the landscape will look like. Also make sure you know exactly what the tour you are booking includes in terms of duration, accommodation options, guide and itinerary. Even if you decide to book a tour on arrival in Uyuni, try to do a little research on the company you choose and check reviews. You’ll need a warm sleeping bag (tour companies provide these, often at an additional charge), and don’t forget to pack warm clothing. Daytime can often feel pleasantly warm in the sun, but after it sets temperatures can easily plummet to around -10°C. If you’re booking a budget tour, expect there to be an additional cost.
Environmental Preservation and Sustainable Tourism.
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.
On both tours, the food was great, and there was plenty of it — we couldn’t even finish everything. The first night’s accommodation (salt hotel) was very clean and comfortable, with fresh bedsheets, towels, and toilet paper provided. Don’t underestimate the altitude and make sure to acclimatise before taking a tour. Most tours are conducted in 4WD vehicles, with the driver also acting as the guide. I’ve done the 3-day Salar de Uyuni tour twice with different agencies, eight years apart, in 2017 and 2025.
During the rainy season (usually December–March), a thin layer of water spreads over the salt surface—sometimes just a few millimeters, sometimes a bit more. As you may have deduced by the name, the salt flats are near Uyuni in Bolivia, the starting point of most tours. The plateau includes fresh and saltwater lakes as well as salt flats and is endorheic. It leaves a permanent imprint on any traveler whether it is the glittering salt plains in the dry months or the fantastical reflections in the rainy seasons, this is a natural wonder which is unforgettable.

- Since the salt flat is already extremely smooth, this water film becomes a near-perfect reflective layer.
- Note that to enter Reserva Nacional de Fauna Andina Eduardo Avaroa, you need to pay an entrance fee of Bs 150 (not included in the tour price).
- If you have time, take a longer tour – you won’t regret it.”
- The vast majority of the visitors arrive at Salar de Uyuni through the Bolivian capital, La Paz.

The best time to see the mirror effect at Salar de Uyuni is during the wet season, which is from December to March. Take altitude seriously, and make sure you acclimatize properly before a tour to fully enjoy the beauty of Salar de Uyuni. If you want to have a chance to see the beautiful mirror effect, you should visit in the wet season, which is from December to March. The best time to visit Salar de Uyuni depends on what you want to see. During the dry season, a thick crust of salt, covered with polygonal patterns, stretches to the horizon.
Following rain, a thin layer of dead calm water transforms the flat into the world’s largest mirror, 129 km (80 miles) across. The crust serves as a source of salt and covers a pool of brine, which is exceptionally rich in lithium. It is now covered by an 8 meter thick layer of salt, which is extremely flat.

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.
It’s also possible to take a tour starting in Tupiza – a great option for those coming from Argentina. It’s also possible to take a tour from La Paz with transport to Uyuni included as part of the package. It’s possible to book ahead or choose a tour company on arrival.
