Scuba
What It Feels Like
Zakynthos scuba is local day-boat diving with Mediterranean cave drama. Operators such as Nero-Sport in Limni Keriou, Zante Diving from Agios Sostis, Eurodivers Zante, and Diver's Paradise run training, try dives, and certified morning boat trips to Keri Caves, Turtle Island, arches, walls, and reefs. The island is best for divers who value geology, visibility, small groups, and conservation rules over big pelagic action.
