Kalekoy is more of a secret and Turkey should proud itself for keeping it well-guarded. Away from the rather nosy tourists and much crowd, this is more of a beach escape that will charm you with its stunning blue waters. Take your camera along, cut off from the rest of the world, hop on a boat (that is the best way to get here), and greet the Mediterranean in all its beauty.
If you are not much into nature photography and are eager for a more urban experience, Mardin is where you should head off to. Mardin is deeply connected to the Mesopotamian Civilisation, and is a lost world, that is perched on a ridge. While it usually attracts history-lovers, this place has a lot for the shutterbugs as well.
