Salar de Uyuni is the largest salt flat in the world but no man made glass.Situated in South American Bolivia it is referred as the World’s Largest Mirror over an area of 4,085 square miles (10,582 square kilometres). A vast reflective surface but the most amazing part is that this large mirror is all natural.
Salar de Uyuni, once a salt water lake, is now having a only one salt lake, at it’s bottom. It’s that brine which is covered by salt flats that’s an exceptionally rich source of lithium, however at present time there is no lithium mined out of Salar de Uyuni.
The reason behind this amazing reflection is the salt flats which is covered with a layer of water during the wet season which turns Salar de Uyuni into a mirror like surface. Spread for miles upon miles, the altitude difference between the highest and the lowest point is less than one meter.
The best time to visit Salar de Uyuni is the whole year actually, it looks different in both seasons, wet and dry. So, it depends on the choice of tourists, the Dry season is from July to November and the wet from December to March. But still November is the best time to go as one can get to see Pink Flamings, who are another highlight of this season.
