Greek islands best for snorkelling

Greek islands best for snorkelling are islands where the sea opens up beneath you, where white rock and hidden caves turn the water glass-clear, where every rocky point hides fish, urchins and light-filled hollows just below the surface.

They are islands where a beach day becomes an underwater day, with calm coves, pebbled entries, boat trips to blue grottos and tavernas close enough to swim back to, and that quiet, goggle-fogged feeling of lifting your head and realizing you’ve been floating and watching for an hour.

Who it suits and why

Best for travellers who keep a mask in their beach bag. Greek islands best for snorkelling suit clear water hunters, boat day lovers and families who want fish not just sand – headed by Zakynthos for Keri Caves blue sea caves, Marathonisi turtle island and Porto Limnionas rock pool channels with Loggerhead sightings, Milos for Kleftiko white caves only by boat 40 to 70 euro and Sarakiniko white rock gullies, Crete for Elafonisi pink lagoon shallows, Balos lagoon and Chrissi Island boat day, Rhodes for Anthony Quinn Bay pebble sheltered and Traganou Caves swim in grottos, Lefkada for Agios Nikitas, Porto Katsiki and Milos beach Lefkada deep blue drop offs, plus Paros for Kolymbithres granite boulders sheltered from meltemi and Monastiri bay, and Corfu for Paleokastritsa six bays and Liapades sea caves. Ideal if you want 10 to 30m visibility, cave light rays and calm morning water.

Less suited to those who want surf waves only and late nights. If you want Mykonos Super Paradise beach club waves and Malia strip 50 bars till 4am, snorkelling islands with 9am boats, reef shoes needed, no touch turtle 5m rule and calm water focus will feel too early and quiet.

Kleftiko Milos and Keri Zakynthos only by boat 30 to 60 euro, Anthony Quinn Rhodes and Paleokastritsa Corfu shore free, turtle Zakynthos protected area.

Base Keri or Laganas Zakynthos for cave and turtle boats, Pollonia Milos for Kleftiko morning calm, Aliki Paros for Kolymbithres wind shelter, Kolymbia Rhodes for Anthony Quinn 5 min walk, Paleokastritsa Corfu for six bay hop. Bring own mask 15 to 30 euro, reef shoes for pebble Milos Zakynthos Rhodes, rash vest for long water time, book boats morning flat sea, hire car 25 to 45 euro day for beach hop and go late June or early September for 26 to 28 degrees air and fewer boats over reef than August 1 to 15 peak.
