The best dive sites in Mykonos include Tragonisi islet with its caves and seals, the Anna II shipwreck at 25 metres on the south-east coast, Lia Reef with rich marine life and 40-metre visibility, Paradise Reef, and the beginner-friendly walls near Agia Anna and Lia. They range from shallow reefs to deeper wrecks and caves.
Mykonos offers a varied collection of dive sites to suit every level, reached by boat from the dive centres. Tragonisi, a small rocky islet off the east coast, is a star site, with a dramatic cave system, rocky reefs and the chance to encounter the rare Mediterranean monk seal, making it one of the most exciting dives. The Anna II, a 62-metre cargo ship resting upright at around 25 metres on the south-east coast, is a superb wreck dive in pristine condition for more advanced divers. Lia Reef, discovered relatively recently and lying at about 24 metres, dazzles with rich marine life including colourful nudibranchs, forests of yellow and black sponges and schools of fish, with visibility up to 40 metres, and suits both newer and advanced divers. Paradise Reef teems with sponges, barracuda, starfish and octopus. For beginners, the gentle wall dives near Agia Anna and Lia, starting at just 4 metres and descending to around 26 with no strong currents, are ideal first dives. This range of reefs, walls, caves and a wreck makes the diving genuinely varied, set out alongside the guide to Lia Beach. Dive centres and courses come next.

What marine life will you see diving in Mykonos?
Diving in Mykonos, you can see octopus, moray eels, barracuda, groupers, bream and schools of fish, plus colourful nudibranchs, starfish, sea urchins and forests of sponges on the reefs. Rocky walls and caves shelter the most life, and at Tragonisi you may even encounter the rare Mediterranean monk seal in the clear Aegean water.
The marine life is one of the great rewards of diving in Mykonos, with the clear Aegean water and varied rocky habitats supporting a surprising abundance. On the reefs and walls you can expect to see octopus tucked into crevices, moray eels, groupers, bream, damselfish and shimmering schools of smaller fish, while barracuda patrol sites like Paradise Reef. The rocks and reefs are carpeted with colourful life, including vivid nudibranchs much loved by macro photographers, starfish, sea urchins, anemones and dramatic forests of yellow and black sponges, especially at the rich Lia Reef. The cave systems and overhangs, notably around Tragonisi, shelter the most life and add atmosphere, and Tragonisi offers the rare chance to encounter a Mediterranean monk seal, one of the world’s most endangered seals. The excellent visibility, often up to 40 metres, lets you take it all in. While the Mediterranean is not as densely populated as tropical reefs, the variety, the clear water and the chance of special encounters make Mykonos diving genuinely rewarding, set out alongside the guide to the beaches. The cost and requirements are worth knowing.

A try dive or single guided dive typically costs around 60 to 120 euros, while full Open Water courses run several hundred euros. The diving season runs roughly May to October when the sea is warm.
Scuba diving in Mykonos is accessible to almost everyone, so a lack of experience need not hold you back.

This is a wonderful taste of the underwater world. Costs are moderate for the experience: a try dive or a single guided dive for certified divers typically runs from around 60 to 120 euros including equipment, while a full multi-day Open Water Diver certification course costs several hundred euros, and packages of multiple dives offer better value. The diving season runs roughly from May to October, with the warmest, calmest and clearest conditions in summer and early autumn, while the centres close in winter.

What tips help for scuba diving in Mykonos?
For diving in Mykonos, book a reputable PADI or SSI centre, dive in the warm May to October season, choose a site matched to your level, and bring or rent a wetsuit as the Aegean is cooler at depth. Allow 24 hours between your last dive and flying, stay hydrated, and avoid alcohol before diving.
A few practical tips ensure your Mykonos diving is safe and enjoyable. Choose a reputable, professional dive centre affiliated with PADI or SSI, with good reviews, qualified instructors and well-maintained equipment, and don’t be shy about asking about safety standards and group sizes. Dive within the warm season of May to October when conditions are best, and pick a site matched to your certification and experience, leaving the deeper wreck and cave dives to qualified, confident divers. Although the surface is warm in summer, the Aegean cools with depth, so a wetsuit is needed and is usually provided; check it fits. Crucially, respect the no-fly rule, allowing at least 24 hours between your final dive and any flight home, which matters given Mykonos trips often end with a flight. Stay well hydrated, avoid alcohol before diving and the night before, never dive beyond your training, and listen to your instructor and dive guide. Bringing your certification card and logbook if you have them speeds things up. With a good centre and sensible precautions, diving is a safe, memorable highlight, set out alongside the guides to Mykonos safety and the airport.
