In which country is the Salar de Uyuni located?
Last Updated:
The Salar de Uyuni is a salty expanse located in south-western Bolivia, in the department of Potosí. Covering an area of 10,582 km², it is considered the world’s largest salt desert.
Situated at an altitude of 3,656 metres, the Salar de Uyuni is the remnant of a prehistoric lake, Lake Minchin, which dried up thousands of years ago, leaving behind this vast expanse of salt. The surface of the salar is remarkably flat, with variations in altitude of less than one metre across its entire surface.
The Salar de Uyuni was formed by the evaporation of several prehistoric lakes. Between 30,000 and 40,000 years ago, the area was occupied by Lake Minchin, which later evolved into several smaller lakes, including Lake Tauca. Over time, these lakes evaporated, making way for today’s salars, including Uyuni.
The Salar de Uyuni represents a major economic resource for Bolivia. It contains a significant quantity of lithium, estimated at around 7% of the world’s reserves, an essential element in the manufacture of rechargeable batteries used in electronic devices and electric vehicles. In addition, the exploitation of salt and other minerals such as potassium contributes to the local economy.
The Salar de Uyuni is a popular tourist destination, attracting visitors from all over the world. During the rainy season, a thin layer of water covers the salar, creating a spectacular mirror effect where the sky is perfectly reflected on the surface, offering breathtaking scenery. Sites such as Incahuasi Island, known for its giant cacti, and the train cemetery near the town of Uyuni are also popular attractions.
Although the salar may seem inhospitable, it is home to a unique biodiversity. Every year, it becomes the breeding ground for several species of flamingo, including the Andean, Chilean and James’ flamingos. The salar islands, such as Incahuasi, are home to plant species adapted to arid conditions, including cacti that can grow several metres high.
The town of Uyuni, located in the immediate vicinity of the salar, is the main gateway for visitors. It boasts a number of tourist facilities, including hotels, restaurants and agencies offering guided 4×4 excursions through the salar and surrounding areas. Excursions generally last from one to three days and include visits to iconic sites in and around the salar.
When visiting the Salar de Uyuni, it’s essential to be prepared for extreme weather conditions. Temperatures can fluctuate considerably between day and night, and the high altitude can cause altitude sickness in some people. We recommend gradual acclimatization, good hydration and protection from the intense daytime sun.
The Salar de Uyuni is one of Bolivia’s natural treasures, offering breathtaking scenery and an unforgettable experience for travellers. Its vast white expanse, clear skies and unique natural phenomena make it a must-see destination for nature lovers and photographers alike.
