At more than 3,600 meters above sea level, the world’s largest salt desert, the Uyuni Salt Flat, spans 10,582 square kilometers and is one of the favorite destinations for thousands of people visiting Bolivia.

Anastasio, a local tour guide from the Andean region of Potosí, told EFE that “the salt settles on the ground during the dry season, and the desert turns white, resembling snow,” a sight appreciated by visitors who take photos and videos, especially at sunset.

The desert can only be accessed with off-road vehicles. Along its edges are hotels built with salt blocks and a park with salt sculptures, one of the tourists’ favorite spots, according to the guide.

Colchani, a small village of artisans who sculpt and harvest salt, lies at the desert’s entrance. It is home to the region’s largest salt factory, estimated to extract over 20,000 tons of salt annually, mostly for human consumption.

Another favorite spot for tourists is Uyuni’s “Train Cemetery,” where dozens of locomotives from the last century sit abandoned, rusting in the open air.

Locals claim that the first railway line in Bolivia was built in this area during the region’s industrial boom in 1889. Today, the trains and their carriages are abandoned, but visitors enjoy climbing on the structures to take photos.

One of the attractions in the area is the illusion photography. By playing with perspectives and the seemingly “infinite” horizon, tourists take photos with toy dinosaurs or llamas, making the toys appear large and the people small, as if they are riding them, Anastasio explained.

Tourists’ favorite phenomenon is the “mirror effect,” created during the rainy season. However, this December, rainfall has been scarce, and visitors have been unable to experience it.

The “mirror effect” in the Uyuni Salt Flat occurs when nearby lakes overflow during the rainy season, creating a layer of water that spreads across the salt desert. This water reflects light, creating the illusion of an infinite sky—ideal for the tourists’ favorite photos.

The Salt Flat’s Lithium

The Uyuni Salt Flat is also considered one of the world’s largest lithium reserves, a mineral highly valued for battery production, energy storage, and other uses.

According to the state-owned Yacimientos de Litio Bolivianos (YLB), Bolivia holds the world’s largest lithium reserve, having increased from 21 to 23 million tons.

On December 13, 2023, an industrial plant was inaugurated in the municipality of Colcha K in Potosí, with the announcement that it would produce 15,000 metric tons of lithium carbonate annually. The initial investment was 669 million bolivianos ($96 million), although production has yet to meet expectations.

In September, the Russian company Uranium One Group signed a contract with YLB to build a direct extraction and lithium carbonation plant in the salt flat. The project is expected to involve an investment of approximately $950 million, aiming to produce around 14,000 tons of the mineral annually.
