Located in the Narlikuyu district of Silifke, the Asthma Cave is located 300 m southwest of the Heaven Cave. Asthma Cave is one of the best reflections of the geographical conditions of the region.

The cave, which is descended by an iron staircase, consists of galleries of 200 m in length. Giant stalactites and stalagmites can be seen in the galleries. Formed by the accumulation of silica minerals in the cave, whose formation dates back to the 3rd geological period, these wonderful structures attract many local and foreign visitors.
