Pamukkale, the "Cotton Castle" is a natural wonder of bright white petrified castles composed over millennia by mineral-rich thermal waters. It is another UNESCO World Heritage site which also houses the ancient city of Hierapolis and you can check out roaming around well-preserved ruins or soaking in a thermal pool. The surreal environs in Pamukkale make it a rich tapestry of nature and culture that offers one-of-its kind experience.
