Il Corno is a boat dive off the western side of San Pietro in Sardinia, built around a volcanic islet with reef walls, canyons, and route choices that let the site work for both easy and more ambitious dives. The walls carry sponges, parazoanthus, and white gorgonians, while the grooves and fissures hold barracudas, amberjacks, groupers, nudibranchs, crabs, shrimp, and other Mediterranean life.

Scuba Diving
Best as a boat-based wall dive with route choice tuned to certification and conditions.

Not a primary freedive site; the deeper wall profile makes scuba the better fit.
Snorkeling
Snorkeling is secondary. The site is mainly about scuba on the reef walls and canyons.
