Salar de Uyuni, the world's largest salt flat, is a breathtaking destination renowned for its otherworldly landscapes, including stunning reflections during the rainy season (December to April). Accessibility can be challenging, with bumpy roads and high altitude (3,656m/11,995ft), so acclimation is crucial. While solo exploration is possible, guided tours are highly recommended for navigation, safety, and enriching the experience with local knowledge. Tours typically range from 1 to 4 days, costing approximately $100-$500 depending on the duration and level of service. Be prepared for extreme temperatures, both hot during the day and freezing at night. The dry season (May to November) offers clearer skies for stargazing and landscape photography, while the wet season provides the mirror effect, but with potential travel disruptions due to flooding.
