After lunch, we drive the direction of Kaklik. Kaklık cave was formed by a subterranean stream that slowly eroded the porous limestone and sulfurous rocks. It began to form over 2 million years ago, and it wasn’t until the roof of the cave collapsed, that people discovered it, after which it was opened to the public in 2002. Water pours in from above, at the cave mouth and covers the surface, creating travertine steps with the calcium carbonate deposit left behind. At the same time, the geothermal spring below the cave pushes water into it from the surface. The movement of the water is clearly visible in the clear blue waters below the sinkhole but also happens elsewhere inside the cave. After the tour, we can drive you back to Pamukkale or Cardak airport.
