The Salar de Uyuni is the largest salt flat on Earth, a dazzling white plain of roughly ten thousand square kilometers at about 3,650 meters in southwest Bolivia. A one-day tour from the town of Uyuni is the simplest way to see it. The route usually begins with the train cemetery on the edge of town, then the salt-processing village of Colchani, followed by a drive across the flat to the Isla Incahuasi cactus island or a similar stop, a long salt-flat lunch, perspective photos and, in the Viator itinerary, sunset on the salt water region with the mirror effect when conditions allow. The endless horizon, the sound of salt crunching underfoot and the sunset colors give the Salar its fame.
Seasons shape the visit. In the wet season, roughly December to March, a thin layer of water can cover parts of the flat and turn it into an enormous mirror, which is why sunset tours are so popular. The dry season from about May to October gives you the hexagonal salt patterns and access to Isla Incahuasi, but no mirror. November is a transition month, so ask the operator what the flat looks like at the time. Cold at night, strong sun by day and thin air mean sunglasses, sunscreen, a warm layer and a hat are essential.
Getting to Uyuni from La Paz is part of the plan. There are domestic flights that take about an hour and overnight buses that take around ten hours or more, and some operators sell a one-day trip from La Paz by bus. A one-day tour from Uyuni town starts in the morning, runs about nine hours and returns after sunset; sunset-focused tours leave later. The Viator tour is a shared group tour, and you should check the language of the guide, the lunch arrangements and the vehicle size in the listing.
Why a day tour: it is the best choice if you are short on time or do not want the basic lodging of a multi-day jeep trip. If you want the colored lagoons, geysers and desert landscapes beyond the flat, consider the three-day trip instead. Book a day or two in Uyuni, as weather, road conditions or blockades can change plans, and the town is small with few things to do besides the tours.
