Historic port-area dive site in Antalya's Kaleiçi marina, where the underwater route can run along both sides of the harbor and into cave-friendly sections. The draw is a compact city-center dive with a mix of harbor structure, overhead features, and a maximum depth that stays within a manageable range for divers who are comfortable with controlled descents. It suits people who want a practical Antalya dive close to the old town, with the cave sections treated as a real overhead-environment consideration rather than casual sightseeing.
