Salar de Coposa

The Salar de Coposa extends across 1,116 square kilometers of land, with 85 square kilometers of salt flats and 5 square kilometers of water surface.

The salt flat basin has served as a natural water collection point for millennia, receiving underground water flows from the Michincha salt flat at 200 liters per second.

The salt flat connects to several ravines that drain into the Pampa del Tamarugal, including Caya, Guatacondo, and Chacarillas, supporting local agricultural practices.

Visitors to Salar de Coposa must prepare for extreme temperature variations and high altitude conditions at 3,741 meters above sea level.

The basin maintains an annual average temperature of 5 degrees Celsius while experiencing a stark contrast between 150mm yearly rainfall and 1,300mm potential evaporation.
