The weirdest view in the world... In the southwest corner of Bolivia lies the Salar de Uyuni: one of the most surreal places on earth. Spread out over more than 4,000 square miles like an ivory ocean, these are the largest salt flats on earth.

Sunrise is one of the best times to see the salt flats at their most spectacular as the sun creeps over the mountains in the background, turning the salt a vivid pink in the eerie morning silence. Camping on the edge of the flats or on one of the islands is a great and unique way to experience this spectacle and you'll be in prime position for the best spot before everyone else arrives.

Where does earth end and sky begin?

Best of all is when the conditions are right and there is a thin film of water over the perfectly flat surface which acts like a vast mirror, reflecting the sky so it becomes almost impossible to tell where land ends and sky begins.
