Scuba Diving in Mykonos

Good to Know

• All diving here is day-boat based out of small local dive centers — there is no liveaboard scene, and you shouldn't expect true shore-entry diving for most named sites; a short RIB ride is standard.
• Depth figures for the Anna II wreck vary noticeably between sources (some say ~25m, others cite an 18-35m range) — treat published depths as approximate and confirm with your dive center before booking.
• The Peloponisos wreck and open-water sites are weather-dependent; the Meltemi winds (strongest in July-August) can make the northeast-coast sites choppy or unavailable on short notice.
• Tragonisi is a protected nature reserve and habitat for the endangered Mediterranean monk seal — divers are expected to keep a respectful distance and avoid disturbing the site.
• Snorkeling versions of several of these same sites (Tragonisi caverns, Lia Bay, etc.) are offered by local operators for those not certified to dive.
• Mykonos has a small dive scene compared to bigger Greek diving destinations (e.g. Crete) — only a handful of named, established PADI centers, mostly clustered on the south/south-east beaches (Paradise, Lia, Kalafati).
• The dive season is seasonal: conditions and visibility are best from roughly May to September; outside that window, options narrow considerably.
• Signature local dive sites include the Anna II shipwreck and the cave/canyon systems around Tragonisi island — good to ask about if you want variety beyond reef dives.
• If you want to freedive, don't assume a structured freediving certification course is available — the main shops rent freediving gear but their advertised course menus are scuba-focused (Discover Scuba through Divemaster); confirm directly if a freediving course is what you're after.
• Full Open Water course pricing wasn't consistently published online — get a direct quote from the shop, as beach location, group size, and included dives can shift the price.
