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 spinmaya no deposit bonus code 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.
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.
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.

The night sky is bright with stars, constellations, and even Milky Way which is perfectly reflected on the mirror-like surface with minimal light pollution and high altitude (wet season). There are reputable travel firms such as Gokite Oman which may help to organize well-curated tours with local Bolivian firms.

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.
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.
How to Get to Salar de Uyuni 🚌
The island is a remnant of an ancient volcanic formation and was once part of a prehistoric lake. It’s a unique landscape featuring giant cacti, some reaching over 10 meters tall, thriving amidst the harsh, salty environment. The salt crusts and brine pools support a rich diversity of microbial communities, including halophilic archaea and bacteria that have adapted to the high salinity and other extreme conditions. The Salar de Uyuni is characterised by high salinity, low humidity, and a significant altitude, creating a challenging environment for most life forms. The savage beauty of this vast salt desert makes it one of South America’s most awe-inspiring spectacles.
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.

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.

Salar de Uyuni is the largest salt flat in the world, with an area of approximately 10,582 square kilometres (4,086 mi2). Sustainability has gained a critical concern as an increasing number of tourists head to Salar de Uyuni. When you are travelling to other neighbouring countries such as Chile or Peru, over land routes via San Pedro de Atacama and Puno are equally beautiful scenic routes as you go. The vast majority of the visitors arrive at Salar de Uyuni through the Bolivian capital, La Paz. According to many travelers it is one of the most intense stargazing moments of their existence.
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.
Now one of the key stops on Salar de Uyuni tours, it’s become something of a tourist trap. The area was once covered by a huge saltwater lake, which dried up some 30,000–40,000 years ago. The focal point of any Salar de Uyuni tour is, of course, the world’s largest salt flat. Known locally as Salar de Uyuni, the salt flats are part of the Altiplano, a vast plateau that extends for 965 km from southern Peru to the southwestern corner of Bolivia. As the largest salt flat on Earth, the Salar de Uyuni is widely regarded as one of the most effective natural calibration sites for Earth-observing satellites. Multiple fatal incidents have occurred at the salt flat as a result of poorly maintained vehicles, untrained drivers, speeding, a disregard for the inhospitable conditions, and lack of regulation for tour companies.
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.
The hotel has a dry sauna and a steam room, a saltwater pool and whirlpool baths. The local communities and tour operators are making efforts to save the delicate salt ecosystem, control the waste disposal system and make sure that the tourism is profitable to the locals. It serves as a reminder of the industrial background of the region and forms a great photo opportunity to the visitors. Salar de Uyuni is also known to have salt hotels wherein even the walls, furniture and bed are designed using salt blocks.
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 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.
