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.
How to Reach Salar de Uyuni
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.
Salar de Uyuni, Bolivia
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.
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.
If you 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.
Tips for Visiting Salar de Uyuni 🤓
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).
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.
- Unfortunately, standard 2-day tours don’t include these highlights.
- Be aware that December and January are the wettest months and sometimes excessive rain can lead to tour cancellations.
- However, despite a small size, Uyuni has comfortable hotels, restaurants, and travel firms which arrange multi-day tours through the salt desert.
- It was once a place of ceremony in Inca times (hausi means house in Quechua).
- Unfortunately, our tour didn’t take us right to the lagoon; we could only see it from far away.
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.
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.
Top 10 Lesser-Known Geological Features Formed Entirely by Water
- 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.
- Very few places on Earth bring together three simple elements—minerals, water, and light—in such a dramatic way.
- It’s a good way to explore Uyuni salt flats as long as you don’t plan to cycle further to the altiplano.
- It was part of a prehistoric salt lake, Lago Minchín, which once covered most of southwest Bolivia.
- 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.
- When we did a tour in 2025, we paid extra for private rooms.
We chose a Spanish-speaking tour, and our basic Spanish was more than enough. It’s worth 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.
When you are Exploring Salar de Uyuni on a multi-day tour, chances are that you will be visiting this nearby reserve. When these ancient bodies of water evaporated due to time they left behind a thick crust of salt and other minerals and this is what we now call Salar de Uyuni. This spectacular salt flat that covers an area of 10,000 square kilometers is not only the largest in the world, but also one of the most astounding natural marvels in the earth. No special permission is required to enter the Uyuni salt flats. Towel and toiletries – these are not provided in standard tour salt hotels and refuges.
Exploring The Area
Collectively, these features make the Salar de Uyuni approximately five times more effective for satellite calibration than the surface of the open ocean. Salar de Uyuni is a popular tourist destination, and consequently a number of hotels have been built in the area. Because of its location, large area, and flatness, the Salar is a major car transport route across the Bolivian Altiplano, except when seasonally covered with water. However, except for January, even in the rainy season the number of rainy days is fewer than 5 per month. It is covered with a solid salt crust varying in thickness between tens of centimeters and a few meters. Lacustrine mud that is interbedded with salt and saturated with brine underlies the surface of Salar de Uyuni.
One-day tours generally visit the Train Graveyard, Colchani, salt flats and Incahausi Island. If taking a multi-day tour of the salt flats, it’s likely you’ll spend the night at one of the area’s unique salt hotels. However, despite a small size, Uyuni has comfortable hotels, restaurants, and travel firms which arrange multi-day tours through the salt desert.
It is estimated to contain around 10 billion tonnes of salt! Salar de Uyuni sits at an altitude of 3,650 metres and covers a staggering 10,000 sq km. (There are no day buses for some reason.) Local buses can be booked on busbud.com.
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 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.
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 spinmaya no deposit bonus code 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.
The thermal waters are delightfully warm and while you’re bathing you can soak up the beautiful scenery. While you might not fancy stripping off when it’s -10°C, you absolutely won’t regret it if you do – trust me! The hot springs of Polques are the perfect place to take a break and relax. Utilising the abundant material to hand, the innovative locals created entire buildings out of salt bricks. (Note that Incahausi can become inaccessible in the wet season due to flooding.) In the middle of the salt wilderness, this tiny oasis is covered in towering cacti.
If you have enough time, I highly recommend taking a 3-day tour. You’ll follow the same itinerary as the first day of the 2-day and 3-day tours. Tour options from Uyuni include 1-day, 2-day, and 3-day tours that end either in Uyuni or in San Pedro de Atacama (Chile). It is located a short drive from the edge of the Uyuni salt flats. From Colchani, you walk on the salt flats to the Dakar Monument and Flag Monument.
