Literally translated from the Turkish as cotton castle, this series of falls and pools is hauntingly beautiful. Nearby Hierapolis, a city around the mineral spa, was destroyed by an earthquake in 60 CE and rebuilt afterwards. Many ruins from the Greco-Roman period can be seen here. The mineral rich pools are good for wading and bathing; however, the smooth surfaces are very slippery.
Hierapolis-Pamukkale is a UNESCO Heritage site.
