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.
On our first tour in 2017, although it wasn’t windy at all, the lake had a greenish tint. In the morning, when most tours come to Laguna, you won’t see the emerald green color. Laguna Colorada, or the Red Lagoon, is a shallow salt lake home to thousands of flamingos. I don’t think this stop was included in tours eight years ago. Another salt flat close to the Chilean border, Salar de Chiguana is a little sister of Salar de 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.
How did this massive salt flat form? (Geological origin)
- Many travellers begin their tour in Uyuni and then continue on to San Pedro de Atacama in Chile.
- So the famous mirror effect is not just pretty—it’s physics, geology, and climate working together.
- Durable and waterproof, with a handy slipcase and an easy-fold format, Lonely Planet’s country maps are designed to let you explore with ease.
- If you’re travelling from Peru, the easiest route is via Peru Hop to La Paz, followed by the overnight bus to Uyuni.
- Your trip starts with the small town of Uyuni that is the central point of the salt flat tours.
- It does not require any special effort, just a submission of relevant documents including your passport, photos, flight itinerary, hotel booking and evidence of financial resources.
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.
Day 2 – Heading south to Laguna Colorada
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.

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 spinmaya no deposit bonus code 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.
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.
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.
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.
In the salt flat, in the middle, there is an island known as Isla Incahuasi that is composed of ancient coral and is covered with giant cacti some of which are over 1,000 years old. It is up to you whether you enjoy the thoughtful amazement of the wet season or the cold magnitude of the dry season, but either way, they will all be a memorable experience with the nature. 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. This is when photographers go a-swarming to get the surreal effect of the infinity horizon, one of the most recognisable photographs of travelling the world.
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 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.
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.
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.

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.
Plenty of travellers opt for the most basic Salar de Uyuni tour and have a fantastic time. There are options for one, two or three-day tours to Salar de Uyuni (some companies also have four-day options). Note that Chile is a much more expensive country to travel than Bolivia and as such tours booked and beginning in San Pedro tend to be more expensive than those in Bolivia. Most tours will visit the geysers at sunrise when the dawn light and rising steam combine to create an ethereal atmosphere.

- In Colchani, there are several hostels, a couple of salt museums, and a souvenir market where all tours stop by.
- Keep the high altitude, strong sun, and wind in mind.
- You are provided blankets in hotels and refuges, but a down sleeping bag will make your sleep more comfortable.
- (Note that Incahausi can become inaccessible in the wet season due to flooding.)
- Mismanagement caused serious environmental pollution and the hotel had to be dismantled in 2002.
A mesmerising and dazzling landscape, this vast salt plain is like nowhere else in the world! Bolivia’s Salt Flats are a breathtaking natural wonder. Read more about visiting Salar de Uyuni independently here. For a group tour that includes an English-speaking guide and more comfortable accommodation with private rooms, you will be looking at around $250USD.
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!
