Best Greek islands for scuba diving

Best Greek islands for scuba diving

Best Greek islands for scuba diving are islands where the Aegean turns deep and clear, where volcanic walls, sea caves, wrecks and reefs lie just offshore, and where a tank on your back is all you need to slip from beach to blue.

They are islands where scuba sets the rhythm, with harbour dive centres, morning boat dives, turtles, groupers and amphorae in the gloom, and long afternoons of sun, salt and debriefing over grilled fish, and that light, buoyant feeling of carrying the deep with you all day.

Who it suits and why

Best for travellers who want tanks not just masks. Best Greek islands for scuba diving suit certified divers, wreck and cave fans and 20 to 30m visibility seekers – headed by Zakynthos for Keri Caves tunnels and arches, Marathonisi turtle cleaning stations and Mizithres walls 5 to 30m, Crete for Elounda WW2 Messerschmitt wreck, Elephant Cave white stalactites and Chania wall drop 12 to 40m, Rhodes for Afandou artificial reef, Lindos sea caves and Anthony Quinn Bay training, Corfu for Paleokastritsa Blue Eye caverns and Liapades reefs 10 to 40m, Milos for Kleftiko white caves and Sarakiniko lava tubes only by dive boat, Santorini for Caldera volcanic cliffs and Thirassia reef 25 to 35m viz, plus Paros for Monastiri and Blue Lagoon beginner friendly. Ideal if you want cave rays, turtles and walls not just beach wade.

Less suited to those who want only ankle deep sand and late clubs. If you want Naxos Plaka shallow wade and Mykonos Cavo Paradiso till 6am, scuba islands with 8am dive boats, 70 to 110 euro two tank days, PADI forms and surface intervals 1 hour will feel too early and kit heavy.
