It's worth the long bus journey to visit Pamukkale & the ancient Roman city of Hierapolis next to it. This was a major tourist site of the Roman Empire. Yes, tourism was a big deal back then too! Hierapolis was a major spa resort with a theater of 15,000 seats! They didn't build it just for the locals. Bring your swim suit as you can still enjoy the baths of Hierapolis today. They have tables & refreshments with changing rooms next to the baths. In summer 2008 it costs $20.00 per person to enter the baths and it's worth it to preserve such a wonderful site. My wife took off her shoes & walked all the way down Pamukkale & back. I spent my time looking at Hierapolis. We met at the baths & enjoyed soaking in the warm hot spring water. We've seen a few sites in Turkey & enjoyed this one very much!
