Siloli Desert, part of the Atacama one, is regarded as the most arid desert in the world: in some points of the desert, rain is absent for centuries. Temperatures ranges from 5° degrees in the night up to 40° in day time, and the composition of the soil is actually similar to planet Mars. Both Hollywood and NASA have used this place as the closest mars-like environment that can be found on Earth. In the frame, the only settlement in the area, Tayka del Desierto, a martian-like hotel at 4,600 meters of altitude, separated hundreds of kilometers from the nearest village.
