Uyuni, located in Bolivia, is home to the world's largest salt flat, the Salar de Uyuni, a mesmerizing expanse that offers a unique travel experience. The best time to visit is during the dry season between May and October when the salt flats are drier and more accessible, though the rainy season from November to March creates a stunning mirror effect. To fully appreciate the Salar de Uyuni and the surrounding natural wonders like the Eduardo Avaroa Andean Fauna National Reserve, it is recommended to book a guided multi-day tour, which typically costs around $200-$300 and includes transportation, meals, and accommodations. Solo travel is possible but can be challenging due to the vast and remote nature of the terrain. Allocate at least 2-3 days to explore the region. Travellers can reach Uyuni by flight from La Paz, or by bus or train from various Bolivian cities.
