Kaklik Cave - or under ground Pamukkale.
Here we are sharing a quote from wikipedia about the KAKLIK CAVE:
Pamukkale has a world-wide reputation. Kaklik Cave on the other hand is less known. Although as a native of the region it is only recently that I have come to know Kaklik Cave. It has been discovered in recent years. Kaklik Cave is 36 km from Denizli, a city in southwest Turkey. If you are travelling eastward from Denizli take a detour of 4 km when you reach Kaklik intersection on the highway.
Chemical sedimentation processes similar to those found in Pamukkale are also at work here in Kaklik Cave. There is a slight difference to the composition of the water though. Upon entering the cave you smell a strong scent of sulphur or rotten egg. I am not a chemist or geologist, so I can only make an educated guess. Here there is a greenish formation on the rocks that may be due to bacterial growth or merely a chemical process. The pools and travertines are stunningly similar to those in Pamukkale although at a smaller scale.
As a travel agency in Pamukkale we organise daily tours to Kaklik Cave. If you are looking for a unique experience rather than spending a full day in crowded tourist groups, we highly recommend to visit Kaklik Cave.
