Located on the Altiplano plateau at a height of 3656 meters above sea level, Salar de Uyuni is the largest flat of salt in the world (12000 square km). The ground is covered in mud mixed with sodium chloride, lithium chloride and magnesium chloride and solid crust with thickness between a few tens of centimeters and a few meters. In the center are a few remnants of volcanic peaks covered with delicate structures, like corals, from algae and fossils.
Salt desert is an amazingly flat. If we consider also the size stretch, sky very clear and extremely reflective surface, make it a perfect place to calibrate the altimeter satellites orbiting the Earth.
Flora and fauna are very poor. Some species of cacti, and some shrubs, shelter Andean fox - Culpeo, Bolivian Vizcacha, three rare species of flamingos and some other species of birds.
Trains cemetery is one of the great attractions of the area. Located outside Uyuni, within a distance of three kilometers, it houses many trains that were abandoned after being used to transport and mining. In the past the city was a distribution hub for the trains were carrying minerals to the ports on the Pacific Ocean. The railway has been built since 1888.
Another attraction is represented by hotels built from blocks of salt extracted from the Salar. The first hotel was built in the middle of the desert, but because it lacked sanitary facilities and polluted surroundings, it was disposed. Then they built another hotels on the edge of the desert, close to access roads, in accord with environmental rules.
Salar de Uyuni is a paradise for lovers of photography. The images captured are of great beauty, no matter whether capture the sunrise, sunset or any other time of day. It is a place worth visiting, and those who have been there have lived original experiences.
