This place is the largest and highest continuous salt lake in the world, becoming a desert during dry seasons, and it’s located in the state of Potosi in Bolivia. It’s believed to contain up to 10 billion tons of salt. The Salar de Uyuni (which Spanish for salt flat) is one of Bolivia’s tourist jewels, because when you walk there it feels like you’ve reached a truly deserted point on Earth (or maybe even on a different planet). Due to their reflective properties, the salt crusts create the perfect mirror, giving the illusion that you’re walking on clouds.
