Ustica — a volcanic island 67km north of Palermo — established Italy's first marine protected area in 1986. Forty years of protection have produced results visible to any snorkeler: groupers (cernie) so large and so unafraid of humans they swim up to your mask, barracuda schools spiraling in the blue, octopus in every crevice, and coral formations on volcanic walls that drop from the surface to 50+ meters. The water visibility regularly exceeds 30 meters. In summer it can reach 40-50m — Red Sea numbers in the Mediterranean. Ustica is the best diving in Italy and among the best in the Mediterranean. The island itself is tiny (8.65 km², population 1,300), has no beaches (volcanic rock coast), one village, and the particular charm of a place that exists primarily for the sea around it rather than the land.

Plan my Ustica trip →Secca della Colombara: A submerged volcanic pinnacle rising from 50m to 6m below the surface. The wall is covered in orange and yellow gorgonian fans, sponges, and anemones. Barracuda school at the top. The signature Ustica dive. Grotta dei Gamberi: A cave system at 15-25m depth with Mediterranean lobsters, moray eels, and the play of light through underwater openings. Scoglio del Medico: A rocky outcrop with enormous groupers (some exceeding 30kg) that have been protected so long they approach divers with curiosity rather than fear. Punta dell'Arpa: Wall dive dropping from 5m to 40m+ — excellent for all levels. Snorkeling: The rocky coastline has multiple entry points where snorkelers can see groupers, octopus, and marine life in 3-8m of water. The marine reserve is divided into zones — Zone A (integral, no entry), Zone B (guided activities only), Zone C (free swimming/snorkeling).
