Salar de Uyuni, Bolivia
Of all the weird places the world has to offer, the Salar de Uyuni in Bolivia has to be one of the coolest. Literally. At 3,700m above sea level, it’s the biggest and highest salt flat in the world, where after dark, temperatures can drop to minus 40 degrees celsius. The best way to explore the salt flat is to hire a 4WD and driver from the Uyuni township. En route, you can even stay at a Salt Hotel, where everything is, quite literally, made from salt: the chairs, beds, tables and even the walls. There’s no heating and the beds aren’t exactly ‘plush’, but it’s worth every salty second.
