Corycian Caves Cennet ve Cehennem

A side road from Narlikuyu (3km/2mi) goes up to the two Corycian Caves or in Turkish Cennet ve Cehennem (Heaven and Hell) with a chapel and various ancient remains. The two huge, collapsed sink-holes (obruk) are sited above a cave system with an underground lake that extends under the sea in the Bay of Narlikuyu emerging as a karst spring. When the sea is calm, the flow of water can be seen from the surface.

While the round 120m/393ft Cehennem (Hell) cave 75m/80yds further east is not accessible, steps lead down to the larger Cennet (Heaven) cave which is 100m/325ft wide and 550m/1,800ft long. What is initially an open pit leads to a deeper cave at the rear. Known as the Typhon Cave (300m/984ft long and 75m/246ft high), the fifth century Chapel of St Mary stands at the edge, guarding the entrance to the underworld where the monster Typhon with a hundred dragon heads and snake feet lived.
