There is no road from San Pedro de Atacama, Chile to Uyuni, Bolivia, but there is a way – dirt road through the Atacama Desert. One should be a genius of GPS to navigate if decides to go by himself. Tour agencies organise 4×4 tours from San Pedro to Salar de Uyuni.
The Atacama Desert in Chile is the place you feel totally out of the planet Earth. The extreme dryness and high elevation make it’s landscapes comparable to Mars surface. In Space Odyssey TV series the Atacama Desert represents both Mars and Venus. And yes, there will be the moments you wish you were in a space suit.
