Salar De Uyuni – Highlight of Bolivia


Salar de Uyuni, amid the Andes in southwest Bolivia, is the world’s largest salt flat. It’s the legacy of a prehistoric lake that went dry, leaving behind a desertlike, nearly 11,000-sq.-km. landscape of bright-white salt, rock formations and cacti-studded islands. Its otherworldly expanse can be observed from central Incahuasi Island. Though wildlife is rare in this unique ecosystem, it harbors many pink flamingos.

Salar de Uyuni is one of South America’s most phenomenal attractions. The vast expanse of white, glistening salt stretches across 10,582 kilometers of the Altiplano and can even be seen from space. Layers of salt are sandwiched between sedimentary deposits that reach a great depth of 10m in the centre of the flat. In total there is an estimated 10 billion tonnes of salt here. However, the real treasure for the locals lies beneath the salt flat, where approximately 70% of the world’s lithium reserves can be found. An entire industry has been devoted to the extraction of this light metal which is responsible for powering laptops, smartphones, and electric cars.

An array of jaw-dropping sites surround this marvelous landscape to produce one of the most extraordinary and unforgettable tours you will ever experience. This magical corner of the world is complete with vibrant colored lakes, bubbling geysers, crazy rock formations and quinoa producing villages. Although it attracts many visitors, it remains one of the world’s most unspoiled and natural landscapes.

In the heart of the Salar de Uyuni salt flats lies Isla Incahuasi, one of the main attractions for most visitors.
This hilly and rocky outcrop of land is the top of the remains of an ancient volcano which was submerged when the area was part of a giant prehistoric lake, roughly 40,000 years ago. The coral composition around the island is a fascinating reminder that the flats used to be part of a gigantic lake.
Incahuasi Island was used as a resting place for the Incas who crossed the lake with llamas loaded with goods for trade in Chile and beyond.

The Cañapa Lagoon is a beautiful water mirror of a greeny tint surrounded by Andean flora and it is possible to observe some flamingoes, wild vicunas and some Andean geese. Cañapa Lagoon is surrounded by three volcanoes: Caquena, Tapaquillcha and Canapa.

Laguna Hedionda is named the stinking lake because of the sulphur that comes out of it, this lake doesn’t have the distinctive bright colors of some of the others here on the list, but it does have flamingos!

The flamingos that appear here and at the Laguna Colorada are part of a separate that are very rare–it’s often thought that they were extinct in the mid-1950s but they still exist in small numbers in the Bolivian altiplano. So, even though they seem to be omnipresent at the Lagoon they are quite endangered. 

The magical red-colored water of Laguna Colorada is the result of red sediments found in the lake. The pigmentation in some of the microorganisms in the water, paired with the red algae, give it its blood-like appearance which encourages people to travel from all over the world to see it for themselves.
There are six flamingo species in the world, and three of them can be seen here: the Chilean, Andean and the James’s Flamingo. The James’s Flamingoes are very rare species and can only be found in the high Andean plateaus. It was rediscovered in 1956, after being declared “extinct”.
Laguna Colorada was nominated to be part of the Seven Natural Wonders of the World.
The jaw-droppingLaguna Colorada has been placed alongside the Salar de Uyuni salt flats as ‘Bolivia’s most incredible natural wonder.’ It’s not hard to understand why when you see its beauty, peculiarity and spectacular setting. The water of the lake is only one meter deep and magnificently shifts between deep blue and dark red. Despite folklore suggesting that the water is the blood of Gods, the bloody red color is in fact caused by red sediments and algae in the water.

Salar de Uyuni Map

The best and most popular way to fully experience Salar de Uyuni is by taking a 4×4 tour across the salt flats. It’s worth noting that shared tours usually accommodate for up to 6 tourists, and thus for a more comfortable experience, a private tour should be arranged. Such tours usually involve a minimum of one nights stay in rather basic accommodation, and thus it is recommended that you bring plenty of warm clothes and a warm sleeping bag for the night. Further, sun cream is a necessity as the reflections from the salt accentuate the suns effect.

Adventurous travellers may also wish to try a night’s stay in one of the areas renowned salt hotels. With no building materials around for miles, some locals have taken it upon themselves to build structures from bricks of cemented salt. In these hotels, everything from the beds and tables to the flush toilets are constructed from salt blocks. Even if you don’t fancy staying, you can usually view these hotels during the day for a nominal fee.

In the dry season, Salar de Uyuni is a surreal experience not to be missed. However, rain takes it to a whole new level. As a thin sheet of water covers the flats, it reflects a perfect representation of the sky above so that it is impossible to tell where sky ends and the land begins.
