The Salar de Uyuni is the world's largest salt flat. It covers an area 10,500 sq km (4,086 sq mi) in size at an elevation of 3,656 m (11,995 ft). The Salar is the product of transformations between several prehistoric lake beds once located in the area between 10,000 and 45,000 BCE. Although usually "dry", the Salar still floods anually. It is estimated that 50-70% of the world's lithium is contained within the Salar de Uyuni, and as a result the area is under threat of industrial development. There is no "best" time of the year to see the Salar. Many prefer the wet season, when surface waters provide unique photo opportunities, and many prefer the dry season when the more remote areas of the Salar are easier to access.
A couple recommendations... Be sure to check out the mummies at the Museo Arqueología y Antropológico de los Andes Meridionales in Uyuni. A trip to Uyuni would be incomplete without stopping there. If you're looking for good eats the pizza at Minuteman Pizza in Hotel Tonito is the best in Bolivia. It's also one of the best places to stay in Uyuni. Take the evening plane down and spend a night in Uyuni. The sunrises are spectacular and you'll feel more rested throught the course of your tour.
