The Kekova sunken city tour from Kalkan is the day on the water with the most history attached to it. You sail east along the Lycian coast on a glass-bottom gulet, drop into the channel between Kekova island and the mainland, and float directly above the staircases, doorways and harbour walls of a Roman-era town that slid beneath the sea after a second-century earthquake.
The route from Kalkan harbour heads east along the coast for about ninety minutes, slipping past Aperlae and into the sheltered channel that separates the long, low island of Kekova from the Lycian mainland. Below you, in three to five metres of clear water, are the remains of a Lycian-Roman settlement abandoned after the great earthquake of AD 141.
Swimming and anchoring directly over the ruins are forbidden under Turkish law to protect the site, but the gulet drifts slowly along the shoreline so you have a clear, twenty-minute pass over the most photographed sections.
After the sunken city, the boat moors below Kaleköy — better known by its ancient name, Simena. A short, steep walk up through the village brings you to a Crusader-era castle perched on the hilltop, with one of the most photographed views on the Turkish Mediterranean.
Lunch is usually served back on the boat after Simena. Üçağız is the small fishing village at the eastern end of the channel — a short stop for ice cream or a coffee on the harbour.
Most visitors take the shared full-day Kekova boat tour. The strongest upgrade is a private Kekova tour from Kalkan: same gulet, your group only, flexible route. Private charters start at around £450 for up to twelve guests.
If you are wondering how to get to Kekova from Kalkan independently — by road, it is about an hour and forty minutes by car each way to Üçağız. Going by sea direct from Kalkan harbour cuts the road element entirely.
The Kekova sunken city is visible year-round, but visibility under the boat varies. The best time to visit Kekova sunken city is mid-May to late June, and again from mid-September to late October, when the sea is calm and the light is low enough to penetrate well.
In high summer the trip still runs daily and the ruins are still clearly visible, but you will share the channel with more boats.
Shared full-day Kekova sunken city tours from Kalkan start at £45 per adult in 2026. The price covers your seat on the glass-bottom gulet, lunch on board, soft drinks at lunch, snorkel kit, the entrance to Simena castle, and minibus pickup.
Bring a hat, sun cream, swimwear, a light layer, and proper shoes for the climb up to Simena castle.
