What is the world's largest salt flat?

The world's largest salt flat is the Salar de Uyuni, located in southwest Bolivia, South America. It spans over 4,000 square miles (10,000 square kilometers) and is situated at an altitude of over 12,000 feet (3,650 meters) above sea level.

The salt flat was formed as a result of transformations between several prehistoric lakes. The salt crust covers a pool of brine that is exceptionally rich in lithium. It is estimated that the Salar de Uyuni contains between 50% and 70% of the world's lithium reserves.

The Salar de Uyuni has become a popular tourist destination, attracting visitors from around the world who come to see the stunning salt flats and the breathtaking views of the Andes mountains. Visitors can take guided tours of the salt flats, explore nearby villages and wildlife, and even stay in hotels that are made entirely of salt.
