What You'll Learn
The reflective lake is caused by the rainy season
The reflective lake in Bolivia is caused by the rainy season. During this time of year, which usually falls between November and March, water accumulates on the surface of the Salar de Uyuni, a salt flat in southwest Bolivia. This creates a shallow "lake" that is just a few centimeters to 20 inches deep. The thin layer of still water transforms the area into a giant mirror, reflecting the sky and clouds above.
The Salar de Uyuni is the world's largest salt flat, covering more than 4,000 square miles. It is located at an elevation of 11,995 feet above sea level and is remarkably flat, with an altitude variation of no more than a few feet across its entire expanse. This extreme flatness, combined with the rainy season, contributes to the formation of the reflective lake.
The Salar de Uyuni was formed thousands of years ago through the transformation of several prehistoric lakes. Over time, these lakes evaporated, leaving behind a salt crust that covers a pool of brine. The crust, which varies in thickness, can be as thin as a few centimeters or as thick as a few meters. During the rainy season, the rainwater collects on top of this crust, creating the shallow lake.
The reflective lake is a popular attraction for tourists and photographers, who flock to the area to capture stunning images of the sky and landscape reflected in the water. The infinite expanse of blue sky and puffy white clouds creates an otherworldly and surreal experience for visitors. The lack of a visible horizon further enhances the optical illusions and unique perspective that can be captured in photographs.
In addition to its visual beauty, the Salar de Uyuni is also a valuable source of minerals, including sodium, potassium, lithium, and magnesium. The brine beneath the salt crust is particularly rich in lithium, with an estimated 22% of the world's known lithium resources found in this area. However, lithium extraction in the region has faced opposition from local communities and presents technical challenges due to the wet climate and high altitude.

It's the world's largest natural mirror
Salar de Uyuni, a mystifying salt flat in Altiplano, Bolivia, is the world's largest natural mirror. It is located at 11,995 feet above sea level and has a reflective surface when covered with water. During the rainy season, usually from November or December to March or April, the flat transforms into a shallow lake, creating a giant mirror. This mirror-like surface reflects the sky and clouds above perfectly, providing a unique opportunity for optical illusions and creative photography.
The Salar de Uyuni's remarkable flatness is a result of its geological history. Thousands of years ago, the area was part of a giant prehistoric lake, Lake Minchin, which eventually dried up and transformed into smaller lakes and salt pans. Today, the salt flat covers an area of 4,086 square miles (10,582 or 10,583 square kilometres), with an altitude variation of less than one meter across its entire expanse. This exceptional flatness, combined with its large area and clear skies, makes it ideal for calibrating satellite radar altimeters.
During the rainy season, a thin layer of calm water, only a few centimetres or inches deep, accumulates on the surface of Salar de Uyuni. This water creates a stunning mirror effect, reflecting the sky and clouds above. The lack of a visible horizon during this time adds to the surreal experience. The mirror-like surface is especially spectacular during sunrise and sunset, when the colours reflected off the water are truly breathtaking. It also provides a unique opportunity for stargazing, as the reflection of the star-filled sky creates a magical atmosphere.
The Salar de Uyuni is a popular tourist destination, offering a dreamlike landscape for photographers and visitors seeking a unique natural wonder. The flat's vast expanse and relative lack of landmarks allow for creative perspective shots and optical illusions. It is also a significant source of lithium, containing an estimated 9 to 10 billion tons, which is enough to power a considerable number of electronic devices.

It's located in the southwest of Bolivia
The Salar de Uyuni is located in the southwest of Bolivia, in the Daniel Campos Province in Potosí, near the crest of the Andes mountains. The salt flat sits at an elevation of 3,656 metres (11,995 feet) above sea level, which means that visitors may experience altitude sickness. To avoid this, it is recommended that travellers spend a couple of days acclimatising at heights of around 1,000 and 2,000 metres. Local advice suggests chewing coca leaves to relieve symptoms.
The Salar de Uyuni is the world's largest salt flat, covering 10,582 square kilometres (4,086 square miles). It was formed around 40,000 years ago by the transformation and evaporation of several prehistoric lakes, including Lake Minchin, Paleo Lake Tauca, and Coipasa. The salt flat is covered by a few metres of salt crust, which serves as a source of salt and covers a pool of brine rich in lithium.
The Salar de Uyuni is a popular tourist destination, particularly during the rainy season from November to March (or December to April, according to some sources), when it transforms into the "world's largest mirror". During this time, a thin layer of rainwater covers the salt flat, creating a perfect reflection of the sky. This phenomenon attracts photographers and tourists looking to capture the spectacular optical illusions caused by the lack of horizon.
The best way to visit the Salar de Uyuni is by taking a three or four-day 4x4 tour across the salt flats. These tours typically depart from the nearby town of Uyuni, although they can also be accessed from Tupiza in Bolivia or San Pedro de Atacama in Chile. Visitors are advised to bring warm clothing and sleeping bags, as the area experiences freezing temperatures at night.
The Salar de Uyuni is not just a natural wonder but also a major transport route across the Bolivian Altiplano and a breeding ground for several species of flamingos. The vast expanse of salt, with its infinite horizon and flatness, offers a unique and surreal experience for travellers seeking to explore the breathtaking landscapes of Bolivia.

It's 11,995 feet above sea level
Salar de Uyuni is located at 11,995 feet above sea level in the Altiplano, Bolivia. The Salar was formed as a result of transformations between several prehistoric lakes that existed around 40,000 years ago but eventually evaporated. The Salar is now covered by a few meters of salt crust, which has an extraordinarily flat surface with average elevation variations of within one meter over the entire area.
The town of Uyuni, which serves as the primary gateway to the salt flats, is located at an elevation of 12,139 feet. The high altitude of the region means that travellers may experience altitude sickness. It is recommended that visitors spend a few days acclimatising to the elevation before beginning any tours. This can be done in the city of La Paz, which has a variety of altitudes, with some parts of the city sitting at around 12,000 feet and others at 10,000 feet.
The unique location of the Salar de Uyuni in the Andean plateau contributes to its remarkable climate and geological formations. During the rainy season (November to March), water accumulates on the surface of the Salar de Uyuni, creating a giant mirror that reflects the sky and clouds above. This phenomenon is due to the flatness of the surface and the lack of horizon. The optical illusions caused by the reflective surface make it appear as though visitors are walking on water or strolling in the sky. The thin layer of water, usually only a few centimetres deep, creates a stunning mirror effect that is a popular attraction for tourists and photographers.
The Salar de Uyuni is not just a visual marvel, but it also holds geological and cultural significance. According to Aymara legend, the mountains Tunupa, Kusku, and Kusina, which surround the Salar, were once giant people. The legend says that Tunupa's tears and breast milk mixed, forming the Salar. Many locals consider Tunupa an important deity and believe that the place should be called Salar de Tunupa.
