The island of Kekova, between Kaş and Antalya, is uninhabited today but in Roman times it was a bustling port — which literally fell into the ocean during an earthquake in AD240. It left behind intact tombs and ancient villas, all perfectly preserved under a metre of crystal sea. Sadly, snorkelling is banned, but by kayak or paddleboard it is still one of the best underwater ruins to visit on a superyacht. Kekova is well worth a visit whether on a private yacht or enjoying a luxury yacht charter in Turkey.
