Occhio di Dio is a Tavolara boat dive with a steep wall, an eye-shaped fissure, boulders, and low-light coralligenous structure. It suits experienced divers who want a deeper, route-driven dive where buoyancy, orientation, and a controlled mooring-buoy entry matter more than easy beach logistics, and where the best dive is the one that stays disciplined along the wall instead of drifting off it.
