Quick answer
Kekova island tours from Kas depart daily between 08:00 and 11:00, with the protected archaeological zone open 08:00–19:00 year-round at no entrance fee. Boat operators navigate a marked corridor above the Sunken City where passengers view submerged foundations, staircases, and amphorae through crystal-clear water—swimming and diving are banned to preserve the ruins. Simena Castle on the adjacent mainland charges a separate fee.
The Sunken City of Kekova lies three to five meters below the surface, visible through the Mediterranean's transparent water as a grid of stone foundations, collapsed walls, and scattered amphorae. A 4th-century earthquake dropped the Lycian settlement into the sea, creating the archaeological corridor that modern boats traverse under strict no-anchor regulations. Tour vessels idle slowly above the ruins while guides point out doorways, staircases carved into bedrock, and the stone quays that once served merchant ships. Kas harbor serves as the primary launch point for the Kekova island tour from Kas, with wooden gulets and modern motorboats departing between early morning and midday. The journey crosses open water before entering the protected zone marked by buoys—captains follow a designated route that keeps propellers clear of submerged structures. Passengers lean over railings to photograph wall remnants and storage jars half-buried in sand, but no one enters the water. The regulation preserves both the fragile ruins and the visibility that makes them accessible without excavation. Simena village, the modern settlement on Kaleköy's shore, offers a hillside Byzantine fortress with Lycian sarcophagi scattered across its terraces. Most boat itineraries include a stop here, giving passengers time to climb to Simena Castle for views across the sunken city corridor and the islands beyond. The castle's small theater, carved into rock, seats ninety and overlooks the bay where Lycian galleys once anchored. Tour operators coordinate lunch stops at waterside restaurants in Üçağız or Kaleköy, where terraces overhang the same clear water that reveals the ruins offshore. The protected area designation means no private kayaks or paddleboards can approach the Sunken City independently—licensed tour boats provide the only legal access. Early morning departures offer the calmest seas and the best light for viewing submerged details before afternoon winds stir sediment. The boat tour from Kas typically runs four to six hours, covering Kekova's northern shore, Simena Castle, and swimming stops at unprotected coves where the seabed holds no archaeological material.

Historical Significance of the Sunken City on Your Kekova Island Tour From Kas
The ancient Lycian city of Dolchiste occupied the northern shore of Kekova Island from at least the 2nd century BCE. Archaeological surveys confirm a thriving settlement with stone houses, public buildings, and a small harbor that served coastal trade routes linking Lycia to Rhodes and Cyprus. The city remained inhabited through the Roman Imperial period, when masonry techniques improved and wealthier families built multi-story dwellings with mosaic floors and storage chambers cut directly into bedrock. A catastrophic seismic event in the 2nd century CE triggered subsidence along the island's northern coastline. Entire residential quarters slid into the sea, leaving stone staircases, doorways, and foundation walls submerged beneath shallow water. Byzantine sources from the 4th century describe the island as partially abandoned, though a smaller community persisted in the elevated interior and on the nearby mainland at Simena. During the medieval period, Byzantine and later Venetian mariners used the sunken ruins as navigation markers, and local fishermen harvested stone from accessible walls. Today, visitors on a kekova island tour from kas glide directly above the submerged remains in glass-bottom boats or sea kayaks. Stone blocks, wall fragments, and the outlines of rooms are clearly visible through the turquoise water at depths of one to six meters. Swimming and diving are prohibited to preserve the fragile archaeological zone, but the clarity of the Mediterranean allows detailed observation from the surface. The Lycian necropolis on the adjacent mainland and the Byzantine fortress at Simena Castle provide complementary views of the region's layered occupation, making Kekova boat excursions a rare opportunity to witness an entire ancient neighborhood frozen beneath the waves.
