The obvious attraction of Pamukkale is the gleaming calcium travertines which are now a world heritage site. Pamukkale actually means "Cotton Castle" and it's easy to see why, with the distinct shape of the travertines. The terraces are formed by a chemical reaction that results in calcium carbonate sedimenting to form a travertine. The calcium rich waters are about 35.6 C when they first come from the ground and flow over the terraces into the beautiful pools.

Above the travertines there is a Municipal pool and the Roman ruins of Hierapolis with the biggest necropolis in the world.
