Located between Kaş and Demre districts, 195 km southwest of Antalya, the ancient Simena, now known as Kaleköy, was a small Lycian coastal city. It was a strategic point from the fourth century BC to today. The most vivid reflection of this feature is the castle that has survived to the present day. It is possible to watch the perfect views of Kekova and its surroundings from this castle.

Kekova, which gives its name to the region, is the general name of both the 7.4-kilometer long island, which is 500 meters from the shore opposite Simena, and the area including Simena, Teimiussa (Üçağız), Aperlai (Sıcak) Pier, Akvaryum Bay, Gökkaya Bay.

Simena is located on the peninsula opposite Kekova Island. The northern coasts of Kekova Island facing Simena are full of traces of the civilization that was partially buried in the water during the earthquakes in ancient times, such as stone stairs, house ruins, pier ruins, half inside and half outside the water, extending to 4-5 meters deep into the sea. Between Kaleköy and Üçağız, the remains of a road and a dock can be seen between the small islets that were used as quarries for sarcophagi.
