6. Kaş-Kalkan: I am going to mention only quite coastal towns so if you are not interested in, you don't need to keep on reading anymore about the title of "where should we visit in Turkey ?".
Kaş is a small coastal town where has local shops, nice restaurants and open air live music cafe/bars. Furthermore, Kekova anthic undersea cities, Patara Beach, Olympos Bay and Lagoon, Saklıkent Canon are among worthwhile near places to visit.
