Situated in southwestern Bolivia, the town of Uyuni is on the edge of one of the most arresting sites on the planet - over 10,000 square kilometres of blindingly white salt. The Salar de Uyuni, or salt desert, was once an inland sea or giant saltwater lake that has evaporated into the thin, dry air of the Andean altitude. All that remains is the salt, tens of meters thick, lying stark beneath a bright sky: a sun-bleached skeleton of a dramatic dead sea. Salar de Uyuni bears a peculiar name fitting to its interesting scenery. A tour of the town of Uyuni and the Uyuni Salt flats is a must for any visitor to Bolivia and is one of the most unique and surreal terrains you are ever likely to see.
