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.

Depth range, seasonality, and planning context.
Reported Depth

Depth Note
The blue tunnel crosses the promontory at shallow depth, while the main chamber has a 17m vault and the narrower tunnels require cave certification.
Best Season
Year-round when the sea is calm enough for overhead diving.
Typical Conditions
Bright white pebbles and filtered light make the cave vivid, but buoyancy and cave-cert limits are the real planning constraints.
