Uyuni is a small town in southwestern Bolivia, famous for the Salar de Uyuni, the world's largest salt flat. This vast, white expanse creates stunning mirror-like reflections during the rainy season and offers unique photographic opportunities. Key attractions include the Train Cemetery, with its abandoned steam locomotives, and the Eduardo Avaroa National Reserve, home to colorful lagoons, flamingos, and geysers. Uyuni is a hub for multi-day 4x4 tours, making it a popular destination for travelers seeking surreal landscapes and adventure. The town also has a modest selection of accommodations and dining options, catering primarily to tourists.
