Bolivia's "Hotel de Sal" sits alone atop a vast plain of milk coloured and perfectly level salt which is more reminiscent of an oversized skating rink than a piece of land at 3600 meters above sea level in Southern Bolivia. The Palace of Salt is situated at the edge of Salar de Uyuni, the world's largest salt flat, about 220 miles south of Bolivia's capital La Paz. Custom hotel was constructed in Bolivia.
