Pamukkale, meaning "cotton castle" in Turkish, is a natural site in Denizli Province in southwestern Turkey. The area is famous for a carbonate mineral left by the flowing of thermal spring water. It is located in Turkey's Inner Aegean region, in the River Menderes valley, which has a temperate climate for most of the year.
The ancient Greek city of Hierapolis was built on top of the travertine formation which is in total about 2,700 metres long, 600 m wide and 160 m high. It can be seen from the hills on the opposite side of the valley in the town of Denizli, 20 km away. Known as Pamukkale or ancient Hierapolis, this area has been drawing visitors to its thermal springs since the time of Classical antiquity.
