Salar de Aguas Calientes III, Salt flat in Antofagasta Region, Chile.
Salar de Aguas Calientes III is a salt flat within a volcanic crater in the Antofagasta Region, sitting above 3900 meters in elevation. The white salt deposits spread across the landscape, surrounded by the stark mountain ranges of the Atacama Desert.
The location developed from a drainage basin that once held a substantial lake, which gradually transformed into the salt deposits visible today. This transformation demonstrates the geological processes that reshaped the high plateau over time.
This area serves as a traditional passage connecting settlements across the high plateau region of northern Chile. The routes used by local communities reveal how people have moved through and across this remote terrain.
Visiting requires careful preparation due to the high elevation above 3900 meters, which can cause fatigue and altitude-related issues. Bring plenty of water and protection against extreme temperature swings between day and night at this altitude.
Natural thermal springs push through the crystalline salt surface, creating pools with varying mineral content and colors. Each spring produces water with a different composition, making the landscape dynamic and visually diverse.
