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.
Also called Turtle Island, Marathonisi offers boulders, canyons, clear water, and marine park context near one of the island's most important turtle areas.
A boataccess reef where divers look for barracuda, groupers, morays, lobsters, and starfish among rock formations around the {{ 18 | distance:m }} to {{ 24 | distance:m }} range.
A classic Mediterranean macro and behavior dive, with octopus, moray, wrasse, sponges, and crevices that reward slow, careful finning.
A photogenic arch and wallstyle profile for divers who want limestone structure, wideangle silhouettes, and a step up from simple reef circuits.
Zakynthos' flagship dive zone for bluelit caverns, shallow cave mouths, walls, and scenic exits.
Operator Checklist
Book the first boat of the day in July and August. Ask operators about marine park permissions, oxygen, emergency plans, maximum group size, and whether the route is suitable for your certification. Do not pressure guides to enter longer caverns if you are rusty. Outside May to October, confirm that boats, instructors, and rental gear are actually operating before buying flights.
