About this spot
Keri Caves on Zakynthos offer accessible cave diving in the Ionian Sea. The site features multiple sea caves carved into dramatic limestone cliffs, making it ideal for divers building navigation and buoyancy skills. Depths range from 5 to 25 meters, allowing you to explore cave entrances and tunnel systems without extreme technical demands. The caves create natural light shafts and shadowed passages that shift with the sun—a visual contrast divers find rewarding. Waters around Zakynthos stay swimmable year-round, though shoulder seasons bring steadier conditions and fewer tour boats. The caves lie close to shore, keeping boat times short and logistics simple. Local dive operators run regular trips here, especially to train newer divers before they move to deeper or more technical sites elsewhere in Greece. The rock formations themselves are the main attraction; expect little artificial reef infrastructure. Be prepared for surge in shallower sections during wind swell, and always dive with a guide familiar with cave entry protocols.

Preguntas frecuentes
›What's the best time to dive Keri Caves?
Year-round diving is possible off Zakynthos. Summer brings calmer seas and better conditions for photography, but also more tourist traffic. Autumn and spring offer fewer divers and reliable weather. Winter can be diveable but sea state is less predictable.
›Is this site suitable for beginners?
Yes. Keri Caves are graded beginner difficulty with depths only reaching 25 meters. The shallow cave sections are ideal for training in navigation and buoyancy control. Always dive with a qualified guide; cave diving requires proper technique even in simple systems.
›What marine life will I see?
Specific species data for Keri Caves isn't widely documented. Expect Mediterranean fish typical of rocky reef habitat—groupers, wrasse, and small pelagics in open water. Cave interiors often host less mobile organisms and anemones. Bring a torch to spot nocturnal species in shadows.
›How do I get to the dive site?
Keri Caves are accessed by boat from shore-based operators on Zakynthos. The island is served by charter flights and ferries. No special permits are required for recreational diving. Local dive shops handle equipment rental and guiding.
