The Uyuni Salt Flat, a vast, dazzling white expanse in Bolivia, is best explored via guided multi-day 4x4 tours typically departing from Uyuni town, as solo visits are highly discouraged due to the remote, challenging terrain and navigation difficulties. Accessibility is limited; it is not suitable for wheelchair users. Seasonal conditions vary: the wet season (December-April) offers stunning mirror-like reflections but can restrict access to certain areas, while the dry season (May-November) reveals an endless white landscape. A typical 3-day/2-night tour, often exploring surrounding lagoons and geysers, can cost approximately $150-$300+ USD, excluding travel to Uyuni. Visitors should prepare for high altitude (over 3,600m), bring warm clothing, ample sun protection (due to extreme glare), and be aware of basic accommodation and facilities on tours.
