There are very few places on Earth where both history and nature lie submerged together, where ancient Lycian sarcophagi rise from the sea like monuments. Kekova is the epicentre of this mesmerising atmosphere. Gliding past the ruins of a 2nd-century Lycian city, sunk by earthquakes, is an experience you will never forget.
How to Choose the Right Kekova Boat Tour
The most professional way to explore Kekova is aboard one of our private or shared boats departing from Üçağız (Theimussa) harbour. Boats from Kaş marina must cross open, often choppy seas, a long and less comfortable route. We strongly recommend driving to Üçağız (or using our transfer service) and starting your tour from the sheltered inner bay.
The highlight of the tour is Tersane Bay, the only spot within the Sunken City zone where swimming is permitted. Float above submerged Byzantine church ruins, spot ancient amphorae and stone staircases beneath you with mask and snorkel, an unforgettable experience.

Simena (Kaleköy): A Paradise Only Reachable by Sea
Imagine a historic village with zero road access, where the sound of motor vehicles has never been heard. Kaleköy, home to Simena Castle, enchants visitors with steep cobbled paths, famously delicious goat's milk Mediterranean ice cream, and the world's smallest Lycian theatre perched at the castle summit. Browse handmade scarves and sage teas sold by local women as you climb; once at the top, the panoramic view of the Kekova island archipelago is the photo of a lifetime.
