This site, located 15 kilometers from San Pedro de Atacama, was declared a Sanctuary of Nature. Its landscape resembles the surface of the moon with small but sharp crested hills formed by the wind, such as the three Maria's and the amphitheater ... 

This valley, located on the Salt Mountain Range bordering the Salar de Atacama, is beautiful for its resemblance to the surface of the moon. This geological site situated at 2,550 meters above sea level, formed 22 million years ago when the folding of the upper strata of the earths crust began to take place. The volcanic activity of the time deposited bits of rock and ash on these folds. Today it is made up of sedimentary rocks with fragments of salt, gypsum, chlorate, borate, and clay. The wind and the atmospheric conditions have carved sculpture shapes with sharp crests, hilltops and waves that transform the landscape into the most extraordinary in our country.

The absence of animal and vegetable life as well as the lack of humidity, make this the most inhospitable corner on Earth.

Moon Valley was declared a Sanctuary of Nature in 1982. The best time of the day to visit the Mayor dune is at sunset on a viewpoint on the summit, where you can appreciate the contrast of colors as the sun is setting over the landscape, making this an unforgettable sight.  

The salt caves are another must visit tourist attraction. Millions of years of rainfall formed these caverns by wearing off the clay and salt of the area and creating beautiful geological shapes, bridges and natural labyrinths. The entrance fee is $1,500 Chilean pesos per person.
