Kaş packs a remarkable range of underwater topography into a compact area. Walls, caves, canyon systems, wrecks and artificial reefs spread across the harbour area and the more exposed sites around Hidayet Bay. Beginners can work through accessible wreck and reef dives such as Fener and the Dakota DC-3, while advanced divers head to drift-heavy sites like Besmi Island or the overhead environment at Tunnel. Indian Lionfish, Mediterranean Moray and Bluespotted Cornetfish are consistently observed across the sites.
Monthly water temperature across Kaş's sites, from satellite sea-surface data corrected for depth. The band shows the site-to-site spread.
Water temperature holds steady through winter and spring before climbing to its warmest in autumn, making the shoulder months of May, October and November particularly rewarding. The best-months data points strongly to May and October as peak periods, when conditions are settled and diver traffic is lower. Sites around Hidayet Bay face open-sea currents that call for careful planning, while the harbour-area sites offer more sheltered conditions year-round.

The harbour area clusters several beginner and intermediate sites close together, including caves, wrecks and reefs, with calmer conditions and one shore-entry option. Hidayet Bay sites such as Besmi Island, Flying Fish Reef and Neptün involve more exposure to open-sea currents and are generally pitched at intermediate to advanced divers. Boat access is required for all Hidayet Bay sites.
Four operators are listed for the area: Nautilus Diving, Kaş Diving, Apollo Diving Center and Dragoman Diving and Outdoor. Having multiple operators means healthy availability across the season, and most sites are reached by short boat trips from the harbour.
