Kekova is a small island located 135 km east of Fethiye and 32km away from Kas. On the northern side there are partly sunken ruins of an ancient town named Xera, which was destroyed by an earthquake during the 2nd century. Rebuilt and flourishing in byzantine times it was finally abandoned because of Arab intruders. At the northwest of the island are the dockyard and the ruins of a byzantine church. All kinds of diving and swimming are prohibited and subject to special permits from governmental offices. You can (and should!) make a trip with a glass bottom boat where you can see still houses, streets and the leftovers of an ancient lifetime beneath the surface of the sea. A few restaurants at the waterfront offer tasty Turkish cuisine, fish being a speciality.
It is forbidden to swim or snorkel over the ruins, the boats may stop at the bays, where swimming is allowed.
All year around, the glass bottom boats are running from May until mid October.
