Pamukkale is one of Turkey’s greatest attractions and probably the location of the most incredible hot springs in the world. “Cotton Castle” which is the literal translation of Pamukkale has been an attraction since ancient times thousands of years ago and no surprise a World Heritage Site. People have been bathing in these pools for thousands of years, and you can to. If the exoticness is not enough for you, the ancient city of Hierapolis is quite literally on top of this white castle.
