Located near the district of Mersin Silifke Narlikuyu, Caves of Heaven and Hell is visited by many travel lovers every year.  These two large pits, which were formed naturally, are also known as sinks, sinkholes and swallets.

Heaven Cave

Hell Cave
The Hell Cave, which is 75 m north of the Heaven Cave, was formed by erosion of the karstic ground structure.  Diameters of the mouth circle are 50 m and 75 m, and cave is 128 meters deep. It is impossible to descend into it due to its concave edges.
