Across its 10,582-square-kilometer (4,086 sq mi) surface, the elevation variation is less than 1 meter (3 ft 3 in) relative to the Earth’s circumference. Around 2007, a new hotel was built, under the name Palacio de Sal, in a new location at the eastern edge of Salar de Uyuni, 25 km away from the town of Uyuni. Mismanagement caused serious environmental pollution and the hotel had to be dismantled in 2002.

• The majority of travellers begin their Salar de Uyuni tour from Uyuni itself.
• 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.
• However, except for January, even in the rainy season the number of rainy days is fewer than 5 per month.
• The area was once covered by a huge saltwater lake, which dried up some 30,000–40,000 years ago.
• 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.
• In reality, its deep red color comes from red sediments and the pigments of algae and microorganisms living in the lake.

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).

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. For private tours expect to pay significantly more. These are shared tours with usually five or six people per jeep.
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.
These months are also less cold than the dry season. Some would argue the vistas during the wet season are even more mesmerising than in the dry season. The rainy season (December to April) brings its own beauty.
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.

• At this time of year you will enjoy the quintessential views of the salt flats, with vast expanses of white landscape extending to the horizon.
• It’s also possible to take private tours for the ultimate customised experience.
• English-speaking guides aren’t standard so check with the tour company if one is included.
• You are provided blankets in hotels and refuges, but a down sleeping bag will make your sleep more comfortable.
• The island is full of giant cacti, it’s awesome seeing them up close.
• (Note that Incahausi can become inaccessible in the wet season due to flooding.)

Salar de Uyuni

It’s basically a natural self-leveling surface. Over time, as climate changed, these lakes expanded during wet periods and shrank dramatically during dry ones. For photographers, scientists, engineers, and travelers, Salar de Uyuni is a place where nature behaves almost unreal. What we see today as a white desert is the long-term memory of ancient lakes, evaporation cycles, mineral precipitation, and climate shifts. Today, she spends her time solo backpacking, navigating through life and unfamiliar streets.
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.

Tourism

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.

Can you visit Salar de Uyuni without a tour?

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.
Across more than 10,000 square kilometers, the elevation difference is barely around one meter.This is almost impossible in natural landscapes. The foundation of Salar de Uyuni goes back to a sequence of lakes that filled the Altiplano basin during the Pleistocene.In the past, huge inland lakes—like the prehistoric Lake Minchin—covered the region. Lisa is a writer and traveller who left her nine-to-five in London for life on the road.

From strange islands in a sea of blindingly bright salt to delicately colored mineral lakes in the Andean mountains, this is an unforgettable Bolivian landscape. When it dried up, it left a couple of seasonal puddles and several salt pans, including Salar de Uyuni. It was part of a prehistoric salt lake, Lago Minchín, which once covered most of southwest Bolivia. The world’s largest salt flat sits at a lofty 3653m (11,985ft) and blankets an amazing 12,000 sq km (4633 sq miles).

Experience guides offer travelers innovative ways to discover iconic destinations, featuring unique adventures and trip-building tools for personalized journeys. The crust is extremely hard—vehicles can drive over it in dry season—yet it has the ability to reshape itself when water interaction begins again. Each polygon is like the surface expression of a slowly growing salt plate. Because of this, NASA and ESA regularly use Salar de Uyuni to calibrate satellite altimeters—something only this kind of surface can offer.

This has direct consequences for lithium extraction, tourism pressure, and local ecosystems. The Salar’s visual magic is not random—it’s atmospheric physics. So the famous mirror effect is not just pretty—it’s physics, geology, and climate working together.
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.
If you spinmaya no deposit bonus code are coming from Argentina it is possible to book tours that begin in Tupiza. Most people time their arrival for the morning of the start of their tour. There is nothing really of interest in Uyuni itself so it’s not worth spending much time here. Be aware that December and January are the wettest months and sometimes excessive rain can lead to tour cancellations. The clear night skies offer great star-gazing opportunities and you’ll also be able to visit some places that aren’t accessible during the wet season.
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.
The first night’s stay in a salt hotel was very clean and comfortable, with fresh bedsheets, towels, and toilet paper provided. In 2017, on the first night, we stayed in private rooms in a salt hotel. If you want to see the sunset at the Salar de Uyuni, ask your travel agency whether it’s included. Most tour agencies start their tours at 10.30 am.
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.
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.
