Even 30 years ago the site of Pammukale had been ruined by too much tourism, destructive tourists and hotels, and a lack of mineral-laden water from which these formations were formed. On the other hand the site of Hieropolis is worth a visit. When I was there they were just begining to excavate the theater and there was an amazing amount of beautifully carved stone still in place. But the best reason to visit this city is the large necropolis. It has a wide variety of tomb styles not seen elsewhere and you can enter some of them and see where families had meals to celebrate their ancestors. Also there is a photogenic triple arch gate to the city.
