Bolivia · Salar De Uyuni
Salar de Uyuni – World’s Largest Mirror, is located within the Altiplano of Bolivia.
At 12106 square kilometers, Salar (salt flat in Spanish) de Uyuni is the largest salt flat in the world. The Salar was formed as a result of transformations between several prehistoric lakes. It is covered by a few meters of salt crust, which has an extraordinary flatness with the average altitude variations within one meter over the entire area of the Salar.
Driving across it when the bright blue skies contrast with the blinding-white salt crust is one of the weirdest and most fantastic experiences. When the surface is dry, the Salar is a pure white expanse of the greatest nothing imaginable – just blue sky, white ground and you. During the wet season, the salt desert is transformed into a enormous salt lak, traversable by both boat and truck. During this time, the shallow salt lake perfectly mirrors the sky, creating bizarre illusions of infinity. The surface perfectly reflects the clouds and the blue sky, and the horizon disappears. If you are driving across the surface at such times, the effect is positively surreal, and it is hard to believe that you’re not actually flying through the clouds.
Salar de Uyuni contains an estimated 10 billion tonnes of salt. Underneath the cemented salt are large reservoirs of lithium-rich brine. In fact, approximately 70% of the world’s lithium reserves are found in Salar de Uyuni and thus it is not surprising that there is an entire industry devoted to its extraction.
In the middle of this seemingly infinite salty lake there is a hotel built entirely out of—naturally—salt. Created from salt bricks held together with salt mortar, the hotel and everything inside it, including the chairs and tables, is made from salt.
