Do you want to step out of your comfort zone and do something you'll remember forever? Then visit Salar de Uyuni. 

Salar de Uyuni, Altiplano, Bolivia is the world's largest salt flat at 10 582 square kilometers (4 086 sq mi/ Salt flats the size of Connecticut.).

 It is in the Daniel Campos Province in Potosí in southwest Bolivia, near the crest of the Andes and is at an elevation of 3 656 meters (11 995 ft) above sea level. A thin layer of water in Salar de Uyuni creates such stunning reflections that probably no words would be enough to describe this incredible beauty. 

Due to the abundance of tours that operate here, visiting the salt flats is feasible despite being remotely located. Visits can be made as a day trip or a multi-day tour, with more extended journeys continuing up to the Chilean border into the alien landscapes. 

Don't expect too much from the lodging as you are in the middle of nowhere, and it is just a place to sleep with shared bathrooms, more of a dorm style. Winter can be frigid in that kind of rooms, and you can rent a sleeping bag from them to keep you warm.
