Probably you arrive to Turkey, by flight to Dalaman or Antalya. Dalaman is preferable as it is closer to Kalkan, about 140 km. To Antalya is the 220 km.

From Antalya you can take a taxi to the bus terminal (Otogar) and from there the bus to Kalkan. Note that the bus does not go after a 20:00 hours. The journey takes approximately five hours.

You can also rent a car.
