Astım Cave is located very close to Cennet-Cehennem Caves in Silifke. It is also called Dilek (Wishing) Cave. The karstic structure of the cave is evident in the stalactites and stalagmites in the cave. Interesting atmosphere of the cave is believed to be good for asthma. Stepping into the cave, the dense air welcomes visitors. Air density increases in the depths of the cave that is accessible by a steep staircase. Visitors must go down the staircase carefully as the moisture in the cave makes the stairs very slippery.
