Kaş is a whitewashed harbour town on the Mediterranean coast of Türkiye, in Antalya province, built straight over the Lycian city of Antiphellos, with sarcophagi standing at its street corners and a Greek island twenty minutes off its harbour, and its water drops away so fast that a few hundred metres off the town beach the bottom is beyond sight, which is why the world's freedivers set their lines here. The town grew over Antiphellos, and in the middle of Uzun Çarşı, the old bazaar street, stands the King's Tomb, a Lycian sarcophagus of the fourth century BC with a high pointed lid and lion heads carved in the stone, while a small Hellenistic theatre of 26 rows sits a few minutes west of the square with no stage building, its seats simply looking out over the water; the sea is swum off the rocks at Küçük Çakıl and Büyük Çakıl, the small and big pebble coves a short walk from the harbour, warmest in August. In Turkish the name means eyebrow, and the arc of the Çukurbağ peninsula is read as an eyebrow over an eye, the island of Meis on the water beyond.
The diving is the town's trade. A C-47 Dakota retired from the Turkish army was sunk deliberately in 2009 and lies intact on the seabed with its twin engines in place, shallow enough for ordinary certified divers, beside a replica of the Bronze Age wreck of Uluburun, found on the cape nearby, and in October 2022 the freediving world championship was held here, when the plankton thins and the water reaches its clearest. The ferry crosses to Meis in twenty minutes, landing in a pastel Greek harbour town where the day is spent swimming off the rocks and eating slowly, and the Lycian Way runs along the coast on either side. Kaş is a town on top of a Lycian port, and the deep water at its door is the reason for the lines.
