Its remarkable design features walls, floors, furniture, and even igloo-shaped roofs constructed from salt blocks that are carefully harvested from the surrounding salt flat. The dry season, which lasts from May to November, offers clear skies and the opportunity to observe the unique hexagonal salt patterns. Many visitors enjoy stopping at the Salt Museum, a quaint space made of salt bricks that features a variety of carved sculptures.
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).
These islands are the tops of ancient volcanic domes that remained above water even when the whole area was a lake.As the lakes dried and the salt crust formed, the domes stayed as isolated high points. Since the salt flat is already extremely smooth, this water film becomes a near-perfect reflective layer. When water levels dropped, evaporation increased.And every time the water pulled back, it left behind thick salt deposits, clays, silts, and evaporite minerals. This is produced by a water layer that sits on top of the salt in the wet season (December to April). It’s also possible to take private tours for the ultimate customised experience.

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. Your trip starts with the small town of Uyuni that is the central point of the salt flat tours. Catch a local bus to Colchani (this is a stop on tours to visit a salt museum).

- Some 30,000 to 42,000 years ago, the area was part of a giant prehistoric lake, Lake Minchin.
- The two seasons have different viewpoints and therefore it is up to you to decide which one to watch depending on the type of experience you want to get.
- Here’s all you need to know about this unique experience.
- During the dry season, a thick crust of salt, covered with polygonal patterns, stretches to the horizon.
- It is estimated to contain around 10 billion tonnes of salt!
- Epic Guides provide inspiration and first-person stories for a lifetime of unforgettable travel experiences.
The second day includes mind-blowing Laguna Colorada and other stunning lagoons filled with flamingoes. They were visibly struggling and choking on the dust kicked up by the tour vehicles. On the way from the Uyuni Salt Flats to the flamingo lagoons, we passed a few tourists cycling along the road. Keep the high altitude, strong sun, and wind in mind. You should be an experienced cyclist and be prepared for long distances. I spent three months travelling around Bolivia, and my trip to Salar de Uyuni was the real highlight.
Isla Incahuasi (Cactus Island)
Today they create an eerie environment and stand as a testament to the corrosive power of salt! The first stop on most tours is the Train Graveyard (El Cementerio de Trenes) on the dusty outskirts of Uyuni. The deserted plain is the perfect canvas for taking perspective photographs and when covered in a layer of water it becomes the world’s largest mirror, which makes for stunning reflective images. Sense of distance and perspective become skewed as the salty surface goes on mile after endless mile. As the water evaporated the salt crystalised and formed a crust, which is up to 10 m thick in some places. There are tours that run directly from the Chilean town of San Pedro de Atacama, which is close to the Bolivian border.
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.
On the 2nd and 3rd days of a standard 3-day tour, you will be taken to beautiful lagoons, and you will see flamingos and vicuñas. Due to the proximity to these international borders, many travelers either start or end their time in Bolivia at Salar de Uyuni. The hotel’s interior showcases the artistry of local craftsmen, featuring intricate salt sculptures and designs that celebrate Bolivian culture.

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.
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.
Top 10 Lesser-Known Geological Features Formed Entirely by Water
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 travel at the end of the tour.
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.
- The tour takes you through elevations ranging from about 3,600 m to 4,800 m.
- In February 2024, the Copernicus Sentinel-3B mission conducted calibration activities over the salar for its Synthetic Aperture Radar Altimeter (SRAL).
- (There are no day buses for some reason.) Local buses can be booked on busbud.com.
- The best time to visit Salar de Uyuni depends on what you want to see.
- 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.
Salar de Uyuni Altitude
The itinerary is similar to the standard 3-day tour, just in reverse, but this route is usually more expensive. Tupiza is another starting point for alternative Salar de Uyuni tours. A 2-day tour from Uyuni covers everything included in the 1-day tour. A 1-day tour from Uyuni is the cheapest option to explore Salar de Uyuni. Most tours to Salar de Uyuni start from the small town of Uyuni.
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.
Warm clothes – the altitude is high, and it gets quite cold at night, and below zero in winter months (June to August). If you don’t like rain and prefer dry weather, visit between May and November. But keep in mind that even in this season, there is no guarantee you will see the reflective effect. Unfortunately, our tour didn’t take us right to the lagoon; we could only see it from far away. On 2025 tour, it was very windy, and Laguna Verde had a bright green color. So there is no guarantee the lake will be green when you come there.
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.
Its unusual shape was formed over time by strong winds eroding the sandstone. They appear as small, pinkish spots in the photo below. On our 2025 tour, the sunset was included in the itinerary, and we had wine and snacks while watching the sunset. There are usually fewer tourists and no entry fee. The island is full of giant cacti, it’s awesome seeing them up close.
We chose a Spanish-speaking tour, and our basic Spanish was more than enough. It’s worth spinmaya no deposit bonus code 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.
