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).

• Most locals make their living from salt production.
• Because of this, NASA and ESA regularly use Salar de Uyuni to calibrate satellite altimeters—something only this kind of surface can offer.
• Drinks were provided with meals, usually water and Coke, and dinners often came with red wine.
• This is a lake of colour; it is a red lake caused by algae and mineral and a home of thousands of flamingos.
• The youngest prehistoric lake was Coipasa, which was radiocarbon dated to 11,500 to 13,400 years ago.

Laguna Colorada (Red Lagoon)

Polques Hot Springs are the most common hot springs stop on 3-day Uyuni tours. Standard tours allow time for taking perspective photos. That’s what it’s like when you visit the Salar de Uyuni, Bolivia’s enormous salt flat that stretches as far as your eyes can see. Alternatively, shorter one- to three-day tours are available from Uyuni or Tupiza, depending on your onward travel plans. Travellers with more time can opt for extended five- or nine-day tours from Salta, Argentina. From December to April, the wet season creates a stunning mirror effect across the salt flats.
Many first-time visitors to the area (including me!) are surprised to discover how much there is to see beyond the salt flat itself. The first such hotel, named Palacio de Sal, was erected in 1993–1995 in the middle of the salt flat, and soon became a popular tourist destination. The lithium in the salt flats contains more impurities, and the wet climate and high altitude make it harder to process. Through its reliable brands such as Gokite Oman, your journey to the largest salt flat in the world will be continuous, natural and memorable. By choosing green tours and taking care of any natural environment, it is possible to ensure that the future generations can still keep Exploring Salar de Uyuni in all its impeccable beauty.

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.

• Very few places on Earth bring together three simple elements—minerals, water, and light—in such a dramatic way.
• It was part of a prehistoric salt lake, Lago Minchín, which once covered most of southwest Bolivia.
• It’s a good way to explore Uyuni salt flats as long as you don’t plan to cycle further to the altiplano.
• 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.
• 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.

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.
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.

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.

How to Get to 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.
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.
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.
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.

Colchani

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.
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.
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.
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.

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.
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 spinmaya no deposit bonus code 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).
Some people decide to skip Isla Incahuasi and just walk around it to save 30 Bs, but I think it’s money well spent. There’s a short walk to the top of the island, and the entry fee is 30 Bs (not included in the tour price). Except for two cacti-filled islands, Salar de Uyuni is completely flat, creating an endless horizon perfect for fun perspective shots. Salar de Uyuni is a paradise for photographers. This is the area where salt is dug up, piled into large pyramid-shaped mounds, and left to dry in the sun.

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.
