Salar de Uyuni in Bolivia is the world’s largest salt flat, stretching more than 4,000 square miles.
It is devoid of wildlife or vegetation and is known for its extreme flatness and clear skies.
This creates a dreamy, mirror-like reflective surface in the wet season and a fascinating pattern of polygonal cracks in the dry season.
Salar de Uyuni comprises over 10,000km² in the Potosi region. The salt is over 10 meters thick in the centre. In the dry season, the salt plains are a completely flat expanse of dry salt, but in the wet season, it is covered with a thin sheet of water that is still drivable.
The standard tour heads south toward the southwest corner of Bolivia, by many fluorescent-coloured lakes that are created from a collection of different minerals from runoff from the surrounding mountains.
At times salt flat is covered in very clear water, making it the largest natural mirror in the world.
An estimated 11 billion tons of salt is believed to be within Salar de Uyuni.
NASA uses this place to figure out the positioning of its satellites. There are 80 species of birds, including three species of flamingos.
It was believed that World’s largest natural mirror was completely flat, but later some small undulations were discovered on the surface.
