Uyuni, Bolivia 🇧🇴

Salar de Uyuni in Bolivia is the world's largest salt flat, a vast salt desert that once was an ancient lake. Its 10-meter-thick salt crust transforms into a giant mirror during the rainy season, blurring the line between sky and earth.

Fun Fact: The salt flat is so vast and flat that it's used to calibrate satellites orbiting the Earth!
