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.
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.
Options for Exploring Salar de Uyuni without a Tour
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.
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.
Underrated Spots in Bolivia: Off-the-Beaten-Path Adventures
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.
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.
- Except for two cacti-filled islands, Salar de Uyuni is completely flat, creating an endless horizon perfect for fun perspective shots.
- From December to April, the wet season creates a stunning mirror effect across the salt flats.
- There are ATMs in Uyuni but these are not always reliable so it’s best to bring some extra cash from wherever you are travelling.
- Lithium is concentrated in the brine under the salt crust at a relatively high concentration of about 0.3%.
- 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.
- Daytime can often feel pleasantly warm in the sun, but after it sets temperatures can easily plummet to around -10°C.
Authorization is only required to store spinmaya no deposit bonus code your personal settings.
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.
Onward Travel ➡️
- Many first-time visitors to the area (including me!) are surprised to discover how much there is to see beyond the salt flat itself.
- In these hotels everything, from the walls and floors to the beds and tables, is constructed from salt!
- 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.
- On both tours our drivers found spots with no one else around and brought dinosaur toys and wine bottles to use in the shots.
- If you don’t like rain and prefer dry weather, visit between May and November.
- While you might not fancy stripping off when it’s -10°C, you absolutely won’t regret it if you do – trust me!
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.
Isla Incahuasi (Cactus Island)
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.
The Salt Hotels
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.
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.
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.
A unique geological feature characterised by small, eye-like holes in the salt flats. Walking across the salt flats allows you to truly appreciate the scale of the landscape and feel the texture of the salt crust underfoot. The Salar de Uyuni in Bolivia offers a variety of activities, from exploring its vast salt flats to discovering the surrounding lagoons and volcanoes. The salt flats, visible from low Earth orbit, display stark white hues that contrast sharply with the darker surrounding rock formations. For much of the year, the salt flats stretch out in a seemingly endless expanse of white, covering about 10,000 square kilometers (4,000 square miles). The salt flat was formed through the gradual evaporation of prehistoric lakes, leaving behind an extensive, flat salt crust.
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.
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.
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.
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 had a bright green color. So there is no guarantee the lake will be green when you come there.
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.
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.
