Scuba
What It Feels Like
Scuba here is local, flexible, and scenery driven: rocky reefs, mild walls, Posidonia edges, caverns, and a few wrecks that sit within normal day-boat or shore-diving logistics. Halkidiki has the denser dive network, with Kassandra sites like Loutra, Porto Ilios, Porto Valitsa, Avlaki, Chrousso, and the Mitilini wreck, plus Sithonia and Kelyfos Island for walls and deeper profiles. Ouranoupoli and Ammouliani add protected boat diving and snorkeling trips. Thassos is easiergoing, with dive schools around Limenas, Skala Prinos, Pefkari, Potos, Limenaria, and Psili Ammos, and boat access to lava rock formations and clear coves.
Signature Sites
Start Here
Boat diving off Sithonia with walls, blue water, and profiles that can suit experienced recreational divers or technical teams depending on the chosen side of the island.
A Kassandra classic where Posidonia gives way to boulders, ledges, overhangs, and wall sections with moray eels, octopus, crinoids, lobsters, and reef fish.
Protected Athos Gulf boat sites with clear water, gentle profiles, and easy pairing with snorkel trips for mixed groups.
Level Up
Thassos' most distinctive named scuba site, associated with cooled lavalike rock scenery and best booked through a local Thassos operator when conditions suit.
Advanced
A compact Kassandra cargo wreck at around {{ 20 | distance:m }}, known for remaining bottle cargo, fish shelter, moray eels, groupers, and seasonal dolphins or tuna around the wider site.
Planning Playbook
Operator Checklist
- Book with a local dive center rather than self-planning independent shore dives. Ask which coast is sheltered for the day's wind, whether the plan is shore or boat based, and whether a wreck permit or specific guide procedure applies. For a two-area trip, dive Halkidiki first, then transfer to Thassos for lighter island dives and snorkel days. Leave a no-fly buffer after your last dive, especially if you are returning through Thessaloniki.
