About Kow Ata Underground Lake
Kow Ata, meaning Father of Caves, is a large natural cavern in the foothills of the Kopet Dag mountains near Ashgabat, home to an underground thermal lake fed by mineral-rich warm springs. Visitors descend a staircase of roughly 200 steps into the cave to reach the lake, where the water stays at a consistently warm temperature year-round, creating an otherworldly swimming experience beneath the earth.
The cave's air is naturally warm and slightly humid, with a distinct mineral scent from the sulphurous water, and the lake's resident population of bats adds to the unusual, almost mystical atmosphere. Many visitors believe the mineral-rich water offers health benefits, making Kow Ata both a curious tourist attraction and a long-standing local wellness destination.
