The magical allure of the Mirror of the Sky: the fantastical Uyuni Salt Flats

By / MOOK Scenic Spots Family Travel Life Network Editorial Team

The Uyuni Salt Flats (Salar de Uyuni), the world’s largest salt flat, is situated in Bolivia. Its nearly 4,000-square-kilometer white landscape makes you feel as though you’re in a dream. The whole lake surface functions like a mirror, earning it the nickname “Mirror of the Sky,” where it’s hard to tell whether you’re walking on clouds or across water. For travelers who love exploring the farthest corners of the world, it’s an absolutely essential experience.

Located at an altitude of 3,700 meters in the mountainous region, the Uyuni Salt Flats present a variety of unique and mysterious faces as weather and light conditions change. Visitors will encounter different sceneries at different times, making the experience truly unforgettable. From July to October each year is the dry season for the Uyuni Salt Flats, when large areas of the salt pan surface dry up, creating a seemingly endless expanse of pure white “hexagonal tiles.”

The Uyuni Salt Flats were formed during the uplift of the Andes Mountains. After experiencing significant geological activity that lifted it from the seabed, numerous lakes filled with seawater were formed. Natural salt pans also emerged, becoming an important local economic activity. During the salt-harvesting season, mounds of salt pile up across the lake surface, creating a rather adorable sight.

These salt products are not only sent to factories for processing but are also used by locals as building materials for houses. The many white-walled buildings in the area originate from this practice. The White Salt Hotel (Hotel de Sal) is one such structure — its walls, beds, tables, and chairs are all made of salt. There’s also the more upscale Palacio de Sal, which even offers saltwater baths and steam rooms, allowing visitors to have a complete “salt journey.”
