Il tunnel is a Capo Caccia cave dive with bright overheads.
Il tunnel is a Capo Caccia cave dive that mixes overhead passages with a rocky wall and a bright white-pebble bottom. The main chamber is wide and light-filled, but the narrower tunnels are reserved for cave-certified divers, so the site is a better fit for experienced teams than for casual reef trips. The payoff is a dramatic Sardinian cave profile with light effects, corals, and plenty of small life.
