Salar de Uyuni is the largest salt flat in the world, measuring 4,086 square miles, with nearly 10 billion tons of salt – nearly 25 times larger than the Bonneville Salt Flats in Utah. Located in Bolivia, mounds of mined salt pepper the landscape. Palacio de Sal, a hotel born out of the Salar de Uyuni, is exactly what the name implies: a palace of salt. Due to the lack of construction materials in the Salar de Uyuni, the Palacio de Sal was constructed with nearly one million blocks of salt. Everything in the hotel – tables, chairs, beds, walls – is all constructed out of salt. Of course, you have to take their word for it, as the hotel asks you to refrain from licking the blocks. Just in case you think you’ll be tempted, have your blood pressure checked upon return.
Rooms at the salt hotel start at $100/night. Amenities include a dry sauna, a steam room, a pool (saltwater, of course), whirlpool baths, the world’s only salt golf course, and the opportunity to experience some of the world’s most incredible sunsets.
