Bolivia’s Salar de Uyuni is one of the country’s wonders. Despite the amount of tourists it still preserves its beauty.

Located in the Andean Plateau in South America, the Salar de Uyuni is the largest salt flat in the world. It is in southwestern Bolivia, close to the border between Bolivia, Chile and north of the Argentinian border. It is over 4,050 square miles and the salt crust stretches to the horizon. It is also 10,000 feet above sea level, as it is located in the Andes. Since the salt is white, the Salar de Uyuni appears to be a large white desert, but during the rainy season, nearby lakes overflow, rivers empty into the salt flat and it becomes filled with water.
Though the seeing the dry, white salt stretch for miles is beautiful, when the salt flat is filled with water, it creates a clear mirror-like lake. Generally, there are only a few centimeters of water so it is still possible to walk on it, but as the weather is unpredictable, some areas become restricted for safety. The salt flat is mostly waterproof, but too much rain will melt some of the salt and make it dangerous to walk on. However, during this time, Salar de Uyuni turns into the world’s largest natural mirror, reflecting the light from the sky. The winter months also have clear skies that offer beautiful stargazing opportunities, the reflected stars only adding to the salt flat’s wonder.
The Salar de Uyuni is large enough to be seen from space, and it contains 10 billion tonnes of salt. 70% of the lithium in the world is also mined from this salt flat. The Salar de Uyuni was created 40,000 years ago, after Lake Michin evaporated. Over the course of its slow evaporation, the salt hardened and created a crust that formed the area into what it is today. In addition, there is still water underneath the salt that continues to evaporate as temperatures rise, which adds more salt to the surface.
Beyond the scientific explanation for the Salar de Uyuni’s creation, the locals have passed on their own legends. In one of them, one of the nearby mountain goddesses, Yana Pollera, gave birth to a baby that two other mountain gods fought over. They both believed themselves to be the father, and Yana Pollera sent her child away to where the salt flat is located today and flooded the area with her milk that eventually evaporated into salt so it would survive. Another legend claims the flat was formed because after two mountain gods were married, the husband left and the wife cried until her tears created the Salar de Uyuni.

Because of its location, there are many tours leaving from Bolivia and Chile, and many of them stretch over the course of multiple days in order to get the most out of the natural beauty. Planes, buses and trains are all able to get to Uyuni, the town closest to the salt flat, but there are also tours from Tupiza, a town south of Uyuni, and San Pedro de Atacama, a town in Chile.
