yep, i agree with basset and kalkan4eva ... if you like Kalkan, Olou Deniz probably wont impress ... unless you'd like to do the paragliding which looks impressive and I'm told is very exciting.
Kaya Koy in the valley is worth a look - the 'ghost village' is quite surreal ... some nice restaurant's in the village - best ones we found were Lavant where you dine beneath the ruins, and Cin Bar where you can do your own barbie!
Patara - a must do, it's tempting to hang out on the beach, but it's well worth a stroll to the ruins and the village ...
