The area is famous for its hot springs and enormous white terraces of travertine, which is a carbonate mineral left by the flowing 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.
Pamukkale Hot Springs can be visited all year long, but it is absolutely spectacular in the winter time, when natural pools of hot water form and tourists can take long, soothing baths.
In this area, there are 17 hot water springs in which the temperature ranges from 35 °C (95 °F) to 100 °C (212 °F). The water that emerges from the spring is transported 320 metres (1,050 ft) to the head of the travertine terraces.
The geological phenomenon that is Pamukkale, literally "Cotton Castle" in Turkish, is also the site of the remarkably well-preserved ruins of the Greek-Roman city of Hierapolis.
Pamukkale is recognized as a World Heritage Site together with Hierapolis. Hierapolis-Pamukkale was made a World Heritage Site in 1988.

From Denizli you can take a bus to Pamukkale.
The best way to approach the ancient site is to walk up through the formations on the travertine path, starting at the south gate to the site. You are not permitted to wear shoes or even sandals to do this, so bring your footwear along in a bag.
