Not far from Ashgabat, just 60 km to the west, is the famous Baharden Cave, inside which is the underground lake Kov-Ata (Kou-Ata), 
known for its healing properties. The name of the lake translates to "father of caves," and its popularity is explained not only by
 its natural beauty but also by the medicinal qualities of its water.
The descent into the cave begins with a steep staircase, which is quite difficult to navigate without a flashlight. 
At a depth of 60 meters, a view of part of the Kov-Ata lake opens up. 
The water is warm, with temperatures ranging from 34 to 37 degrees Celsius. 
The depth of the lake varies from 8 to 14 meters, though active water activities are prohibited here. 
The water in Kov-Ata lake contains 38 elements, including iodine, magnesium, iron, bromine, potassium, sodium, sulfate, and others. 
Bathing in this water helps improve blood circulation, treats rheumatism, skin and kidney diseases, relaxes the nervous system, 
and positively affects the entire body. However, it is recommended not to stay in the water for more than 20 minutes. 
There is also a legend that during the Parthian kingdom, wounded rebel slaves found healing in these waters.
