2Bolivia–Chile Border: Salar de Uyuni

The Bolivia-Chile border crosses the surreal landscapes of Salar de Uyuni, the world’s largest salt flat.

This otherworldly expanse reflects the sky like a giant mirror during the rainy season, creating a dreamlike setting.

The nearby Eduardo Avaroa Andean Fauna National Reserve, with its colorful lagoons and volcanic peaks, makes this border an extraordinary destination for nature lovers and photographers alike.
