If you haven't visited before, Saklikent and Tlos are worth seeing, as is Xanthos. Then onto Patara maybe? Stay in Kalkan overnight, then travel along the coast road to Kas. I don't know if you are interested in history, some people are, leaves others cold! But there is a well preserved theatre in Kas. As Nicola suggested, perhaps a trip to Meis from Kas. Then to Ucagiz, and a boat trip along the coastline to see the sunken city of Kekova. Simenon castle worth a walk up to if only for the views. Visit the cafe that sells home made ice cream on the way back down from the castle,delicious! Yes I would stay at one of the pensions in Ucagiz.Maybe then onto Adrasan or Cirali, and go to see the Chimaera at Olympus. Stay in a tree house at Olympus. Think maybe you need more days! Or you could return and do those you have missed......
