It's not every day you get to touch the sky. But in Salar de Uyuni in Bolivia, it's quite the opposite. Covering over 10,000 square kilometers (thats over 4,000 square miles), the world's largest salt flats are situated near the crest of the Andes mountains.
The flats are nearly 12,000 feet above sea level and formed from transformations of several prehistoric lakes tens of thousands of years ago.
In the dry season, the planes are flat and crusty because of the salt (it's actually over 30 feet thick), but during the wet season, the flats are covered with a thin sheet of water that creates the amazing ice-like reflective surface.
While you're in the area, you should definitely check out the Laguna Colorada, or the Colorful Lake in English. It's red because of the algae that lives in it and you won't be able to miss the bright coral flamingos that hang out there as well.
