The name comes from the tunnel that crosses the cape of the bay of the “submarine”.
This passage, 80 meters long, develops to a maximum depth of 18 meters. The feeling is impressive: a huge gallery, full of caves and tunnels! Following the main passage we arrive in the bay of the submarine, a rock that takes its name from its peculiar shape, where, especially with the light of the afternoon and with the clear water above us, we can see the beautiful cliffs of Capo Caccia.
Once we round the rock, we go back into the tunnel, through small passages full of lobsters and stenopus, to return to the bay where we dropped the anchor. Such a good feeling: back where we started our dive relying only on our expert guides.
