Exploring Salar de Uyuni: Bolivias Stunning Salt Flat

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.

Environmental Preservation and Sustainable Tourism.

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 spinmaya no deposit bonus code had a bright green color. So there is no guarantee the lake will be green when you come there.

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.
Salar de Uyuni, located in southwest Bolivia near the crest of the Andes, is a remarkable natural area set in a high-altitude environment. One must-do activity in Bolivia is exploring the Salar de Uyuni, the world’s largest salt flat. Bolivia, located in the heart of South America, offers diverse travel experiences that can be enjoyed on a budget.

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.
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.
Snacks and water/drinks – food is provided, but in case you want extra in between the meals, pack some snacks and drinks. Sunblock, lip balm with SPF, and sunglasses – the sun is very harsh at high altitudes. You are provided blankets in hotels and refuges, but a down sleeping bag will make your sleep more comfortable. A rain jacket if you go during the wet season.
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.

Not sure where to start?

• Remnants of a former era, the disused trains lie abandoned and rusting in the salty winds.
• They appear as small, pinkish spots in the photo below.
• The itinerary is similar to the standard 3-day tour, just in reverse, but this route is usually more expensive.
• For travelers seeking the most comprehensive insights.
• Due to lack of conventional construction materials, many of them are almost entirely (walls, roof, furniture) built with salt blocks cut from the Salar.
• Drinking water and drinks are more expensive than in the town of Uyuni.
• We’ve compiled the definitive list of the best places to visit – all year long – when the crowds dissipate and the local vibe comes to life.

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.
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.

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.

• 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).
• For the adventurous, cycling or hiking across the salt flats is possible, but requires preparation and experience in arid environments.
• 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.
• 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.
• The island is full of giant cacti, it’s awesome seeing them up close.

Be warned that the accommodation on the budget tours is likely to be very basic. These are shared tours with five or six people per jeep and often with a Spanish-speaking guide. If you have time, take a longer tour – you won’t regret it.” If you’d like to explore further afield and get out into the surrounding landscape then opt for a two- or three-day tour. Another popular option for travellers heading north from Chile is to take a tour from the border town of San Pedro de Atacama.
