Pamukkale
Pamukkale is famous for its snow white terraces, but this is not the only attraction - the remnants of ancient Hierapolis are equally impressive.
A very beautiful place. Especially, the old necropolis is very attractive and much less crowded than the terraces and the Roman bath.
By the way, the terraces had almost been destroyed by tourism and only after demolition of some hotels taking their calcium rich water and strict regulation of the access to the terraces (most are completely off limits, you can walk some, but only without shoes) they could be restored to their orginal white splendour.
