I've never been to a UNESCO World Heritage Site that wasn't awesome and amazing, and Hierapolis is certainly no exception. Just amazing. Can't even subtract because of the very annoying group tours and numerous underqualified guides, you really don't need a tour guide. What you want instead is a good guidebooks, Rick Steves, Lonely Planet, National Geographic, or DK Eyewitness Guide. Also, admission price includes an audio tour, they do give you blue tooth earpieces but I would bring your own so they are fully charged. The audio tour is pretty good and certainly much better than the live guides who often just make stuff up. A little less crowded than Ephesus, and not bad at all during the cold offseason. Much of the annoying groups are more enamored with the hot springs part than the ancient ruins as well. 200 meters high overlooking Pamukkale (cotton growing and textile processing area, hence the name of our hotel, the Cotton House), Founded by the Hellenistic Attalid kings of Pergamom at the end of the 2nd century B.C.E., at the site of an ancient cult. Its hot springs were also used for scouring and drying wool. Ceded to Rome in 133 B.C.E, Hierapolis reached its peak 3rd century CE. An earthquake in 60 CE resulted in massive destruction. Remains of the Greco-Roman period include baths, temple ruins, a monumental arch, a nymphaeum, a necropolis and a theatre. Following the acceptance of Christianity by the emperor Constantine and his establishment of Constantinople as the 'new Rome' in 330 CE., the town was made a bishopric. As the place of St. Philip's martyrdom in 80 C.E., commemorated by his Martyrium in the 5th century, Hierapolis with its several churches became an important religious center for the Eastern Roman Empire. There's a lot to see here over a pretty wide area, do not miss the amphitheater. read more
