2Bolivia–Chile: Salar de Uyuni

The Bolivia-Chile border crosses through one of the most surreal landscapes on Earth—Salar de Uyuni, the world’s largest salt flat. During the rainy season, the flats transform into a giant mirror, reflecting the sky in a way that defies reality.

This otherworldly border is complemented by the nearby Eduardo Avaroa Andean Fauna National Reserve, with colorful lagoons, flamingos, and volcanic vistas adding to its charm.
