Wreck Diving in Greece: 19 Sites Where History Meets the Sea

Greece isn't the Caribbean, and that's exactly the point. The Aegean and Ionian seas hold centuries of maritime traffic — warships, cargo vessels, aircraft — resting on seabeds that divers can reach without extreme technical training. With 19 mapped sites across islands from Thassos in the north to Crete in the south, and water temperatures that stay diveable year-round, Greece rewards the diver who does their homework.

Best wreck and dive sites in Greece

• Santorini — Caldera Wall — Intermediate divers, 12–40 m. The volcanic caldera wall drops sharply and the visibility here makes depth orientation straightforward. A strong site for divers comfortable with deeper profiles.
• Zakynthos — Keri Caves — Beginner-friendly, 5–25 m. Shallow enough for newer divers, with cave passages that reward slow, patient exploration. A good warm-up before committing to deeper wrecks.
• Crete — El Greco Cave (Akrotiri) — Intermediate, 8–25 m. Akrotiri's coastline hides this cave system within easy reach of the surface. Pairs well with other Cretan sites on a liveaboard or multi-day trip.
• WWII Fighter Plane Wreck — Intermediate, maximum 7 m. One of Greece's most historically specific dive objects — a World War II aircraft resting in very shallow water. The shallow depth makes it accessible but the historical weight makes it memorable. Exact location is operator-dependent; book through a local dive centre who knows the current site condition.
• Center Action Thassos — Intermediate. Thassos sits in the northern Aegean, cooler and less visited than the island chain further south. The site suits divers looking to avoid high-season crowds.
• Mononaftis — Beginner. A manageable entry point into Greek diving, suitable for those completing their first open-water dives in-country.

When is the best time to dive in Greece

Greece is diveable year-round. Water temperature ranges from 13°C in winter to 26°C in peak summer. Most visiting divers arrive May through October when surface conditions are calmer and temperatures sit between 20–26°C — a 3mm wetsuit is comfortable. Winter diving (13–16°C) requires a 5–7mm suit but delivers better visibility and empty sites. Spring and autumn are the practical sweet spot: warm enough for a 5mm, uncrowded, and with good light angles for photography.

Is Greece good for beginner divers

Yes, selectively. Sites like Keri Caves in Zakynthos and Mononaftis are explicitly rated beginner-level, with shallow maximums and calm conditions. The WWII aircraft wreck tops out at 7 m — well within a newly certified diver's range. Intermediate sites like the Caldera Wall at Santorini require buoyancy control at depth and should not be the first dive of a trip.

What you'll see

Greece's recorded marine life data is still being compiled across the 19 mapped sites. Divers consistently report Mediterranean fauna typical of the Aegean — octopus, moray eels, sea bream, and occasional grouper around rocky structure and wrecks. The WWII aircraft site adds a specific historical layer that pure reef dives don't offer.

FAQ

Do I need a dive certification to dive wrecks in Greece? Yes. Most wreck sites require at least an Open Water certification. The WWII aircraft at 7 m is accessible to newly certified divers; deeper sites like the Caldera Wall require intermediate experience.

Can I dive year-round in Greece? Yes. No month is off-limits, though winter requires thicker exposure protection and some operators reduce schedules outside peak season.

Which island has the best wreck diving? Based on mapped sites, Zakynthos and Crete offer the most variety across skill levels. The WWII aircraft wreck is the most historically distinctive single object in the dataset.

How cold does the water get? Minimum recorded is 13°C in winter months. A 7mm wetsuit or drysuit is appropriate then. Summer peaks at 26°C.
