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.

• For photographers, scientists, engineers, and travelers, Salar de Uyuni is a place where nature behaves almost unreal.
• This is produced by a water layer that sits on top of the salt in the wet season (December to April).
• Make sure you know what the weather will be like before you book a tour and therefore what the landscape will look like.
• There was so much more to see than I expected and the locations on days two and three were far less crowded because there were no daytrippers at these sites.
• A 1-day tour from Uyuni is the cheapest option to explore Salar de Uyuni.
• Online Stopwatch allows you to record the time segments and laps with high accuracy.
• Many visitors enjoy stopping at the Salt Museum, a quaint space made of salt bricks that features a variety of carved sculptures.

Salar de Uyuni, Bolivia

English-speaking guides aren’t standard so check with the tour company if one is included. Unless you’re confident in your Spanish skills, you’ll likely get more out of a tour with a guide who speaks English. There was so much more to see than I expected and the locations on days two and three were far less crowded because there were no daytrippers at these sites.

The structure of the salt crust (Polygons, fractures, micro-textures)

Uyuni itself offers little of interest and so it’s best to avoid spending more time here than necessary. Salar de Uyuni sits at 3,656 m.a.s.l. and some parts of the tour reach altitudes of above 4,500 m. Many travellers begin their tour in Uyuni and then continue on to San Pedro de Atacama in Chile. When booking a tour you’ll have the option of taking a round trip or including onward spinmaya no deposit bonus code travel at the end of the tour.

Solar de Manaña geysers are located at an altitude of more than 15,912 ft/ 4,850m. Make sure to charge your devices during this time. 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). In reality, its deep red color comes from red sediments and the pigments of algae and microorganisms living in the lake. According to the local folklore, the water in Laguna Colorada is the blood of the Gods. It sits at an altitude of 14,000 ft/ 4,270 m in Eduardo Avaroa Andean Fauna National Reserve, close to the Chilean border.
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.
It’s an absolute must-visit if you’re exploring Bolivia and South America. It’s a vast expanse of salt stretching to the horizon. If you’re travelling from Peru, the easiest route is via Peru Hop to La Paz, followed by the overnight bus to Uyuni. The most popular starting point for exploring Salar de Uyuni is the town of Uyuni, especially for travellers coming from within Bolivia. December offers the most sunshine, with an average of 7 hours of sunlight per day. January is the hottest month in Uyuni, with an average temperature of 15 °C (59 °F), while July is the coldest, averaging 12 °C (54 °F).

Conclusion — where salt, water, and light meet

I am not a fan of commercial tours and wanted to experience Salar de Uyuni independently. South America has stunning salt flats, but Salar de Uyuni is the world’s largest at about 4,674 sq mi (12,106 sq km). Be sure to check out the Dakar Rally monument located in Colchani, right at the edge of the salt flats.

• In 2017, on the first night, we stayed in private rooms in a salt hotel.
• Salar de Uyuni is one of those rare landscapes that feels like Earth trying to show what it’s capable of.
• The rainy season (December to April) brings its own beauty.
• Alternatively, shorter one- to three-day tours are available from Uyuni or Tupiza, depending on your onward travel plans.
• We saw a couple of people cycling on the Uyuni salt flats.
• They were visibly struggling and choking on the dust kicked up by the tour vehicles.
• When booking a tour you’ll have the option of taking a round trip or including onward travel at the end of the tour.

The visitors can see the panoramic views of the salt expanse making it appear to be infinite in all directions as seen on top of the mountain. Vast reserves of untapped lithium lie beneath the salt flat, and in the early 21st century the Bolivian government discussed options and feasibility for its extraction and production. This travel guide covers what to do, how to get there, where to stay, and useful tips from our experience. Yes, you can visit Salar de Uyuni independently without booking an organized tour.
There are ATMs in Uyuni but these are not always reliable so it’s best to bring some extra cash from wherever you are travelling. Note also that Incahausi island is sometimes inaccessible during the rainy season. Some people are keen to observe the mirror effect on the salt flat. Aim to begin your tour the same day, otherwise you’ll have a whole day to waste.
The majority of travellers begin their Salar de Uyuni tour from Uyuni itself. Here are some of the key differences between the plethora of tours on offer. A multi-day Salar de Uyuni tour is essentially a tour of the reserve. In these hotels everything, from the walls and floors to the beds and tables, is constructed from salt!
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.
On both tours our drivers found spots with no one else around and brought dinosaur toys and wine bottles to use in the shots. The Dakar monument is made of salt, and the flags were left by travelers during their visits. It’s located near the Argentine border and a bit farther from the Uyuni salt flats. In Uyuni, there are plenty of travel agencies offering Salar de Uyuni tours. Unfortunately, standard 2-day tours don’t include these highlights.
In Colchani, there are several hostels, a couple of salt museums, and a souvenir market where all tours stop by. It’s a good way to explore Uyuni salt flats as long as you don’t plan to cycle further to the altiplano. We saw a couple of people cycling on the Uyuni salt flats.
Salar de Uyuni is by far the jewel of South America to those travelers who want awe-inspiring beauty and mystery and to have an adventure that they will remember. On its shores are saltworks at Salinas de Garci Mendoza on the north, Llica on the northwest, and Calcha on the south. I only recommend services I’ve either personally used, thoroughly researched, or consider reliable based on reputation and reviews. This is the most popular itinerary and absolutely worth your time and money. Toys, bottles, etc, to take fun perspective photos. Drinking water and drinks are more expensive than in the town of Uyuni.
Learning about the cultural aspect of Uyuni will enhance the experience of your trip to be not only a trip of sightseeing, it will be a good experience of humanity. You may also observe how the salt is extracted, processed and rolled into souvenirs, which is an ideal method of helping communities locally. Excursion to the nearby villages such as Colchani where people make their living by making artisan salt and craft through the traditional ways. Other than its natural beauty, the area surrounding Salar de Uyuni is very culturally diverse.
But in the wet season, a thin layer of water transforms the surface into the world’s largest mirror, reflecting the blue altiplano sky and the clouds. We visited these hot springs on our 2017 tour. There is some variation in which hot springs are included in Uyuni tours, depending on the agency. On our first tour, it wasn’t part of the itinerary, but our driver still offered to take us to watch the sunset before heading to the salt hotel. And the views of the salt flats from up there are absolutely incredible.
A hot spring area with geysers and steaming vents, offering a unique geological experience. Isla Incahuasi, also known as Cactus Island, is a small, rocky outcrop located in the middle of the Salar de Uyuni, the world’s largest salt flat, in Bolivia. 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. It holds half of the world’s lithium reserves and its vast, flat surface makes it an ideal location for calibrating satellite radar altimeters, which measure surface topography.
