Reserve an early morning for a trip to Mount Nemrut, for the place looks nothing less than otherworldly at dawn. At its top lies the 2000+ year old tomb of King Antiochus of Commagene, which is a sight in itself. Take a lightweight camera along, for the hike to the top is rather steep yet totally worth the views.
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.
