Atacama Desert: the driest desert in the world

The Atacama desert is located in northern Chile, along a strip of land between the Andes mountain range and the Pacific ocean. This desert occupies an area of over 100,000 sq km and extends between the border with Peru and 30 ° south latitude.

It is a territory rich in saltpetre, formed by a desert of rocks and stones, dominated by the imposing volcanoes of the Andes, with an altitude varying between sea level and 4,000 meters. In the large plateau is the variety of natural landscapes, there are salt marshes, volcanoes, lakes and geysers.

This desert is considered the most arid and driest desert in the world. The driest part of the desert is located south of the Loa River between the Sierra Vicuña Mackenna and the Cordillera Domeyko. Here the rainfall is completely absent, the temperature variations between day and night very high.

These parks protect a fantastic plateau full of lakes and volcanoes located in the far north of Chile where the ceremonial sites of the Aymara people are also located.
