Sicily blends volcanic underwater landscapes, WWII wrecks, and outstanding marine reserves from Ustica to Plemmirio.
Sicily offers divers a unique blend of volcanic seascapes, wartime wrecks, and exceptionally clear waters. As the largest island in the Mediterranean, it is surrounded by diverse marine environments that cater to every level of diver.
Ustica, a small volcanic island north of Palermo, was Italy's first marine reserve established in 1986. The waters here are among the clearest in the Mediterranean, with visibility regularly exceeding 40 metres. Underwater caves, arches, and dramatic walls host groupers, barracudas, and rich invertebrate life. Diving is regulated by the reserve authorities; book through an authorised centre to explore all three zones.
The Aeolian Islands — Lipari, Vulcano, Panarea, Stromboli, Salina, Filicudi, and Alicudi — are a UNESCO World Heritage site of volcanic origin. Underwater, the volcanic activity creates unique scenery: fumaroles releasing gas bubbles, black lava formations, and thermal vents. The Secca del Capo off Lipari and the underwater hot springs near Vulcano are must-dive sites. Stromboli offers night dives with the glow of lava above.
The Egadi Islands (Favignana, Levanzo, Marettimo) lie off the western coast near Trapani. Marettimo is the crown jewel: pristine waters, deep drop-offs, and underwater caves rivalling any in the Mediterranean. The Cala Bianca and Punta Troia sites are exceptional. Favignana features the historic mattanza tuna fishery waters, now teeming with marine life.
Sicily's strategic position during World War II left numerous wrecks scattered across its seabed. Sunken aircraft, cargo vessels, landing craft, and submarines have become artificial reefs, covered in sponges, anemones, and corals. Notable wrecks include the Bristol Beaufighter near Marsala and several vessels off the southern coast from Operation Husky (1943).
The Strait of Messina is known for powerful currents that attract experienced divers seeking pelagic encounters — tuna, swordfish, and dolphins pass through regularly. South of Syracuse, the Plemmirio marine reserve protects 14 km of rocky coastline with caves, overhangs, and sandy patches. Dusky groupers, moray eels, and octopus are abundant here.
The best season for diving in Sicily is May to October, with water temperatures ranging from 18°C in spring to 27°C in late summer. Visibility peaks in June and September. With EviDive, you can find certified centres across the island to match your level and interests.
