Tour this Uyuni photo and video gallery. The Salt Beds (sometimes called Salt Flats) at Uyuni are one of the more amazing tourist attractions in Bolivia. Stretching as far as the eye can see, the Salar de Uyuni was left behind when Lake Minchín dried up 40,000 years ago. The salt desert is about 120 meters thick and you can stay at a hotel made completely out of salt bricks. Visit our Salar de Uyuni home page for more.
