About Il Corno
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.
