The dive
A large, bright cavern full of life, with coral and yellow Leptopsammia and Parazoanthus on the walls and ceiling; schools of barracuda often swim in front of the entrance.
Profile and sections
A large, bright cavern full of life, with coral and yellow Leptopsammia and Parazoanthus on the walls and ceiling; schools of barracuda often swim in front of the entrance. There are air bubbles under the ceiling. On a south-facing wall a long passage begins, leading to a chamber with stalactites stuck in a dune of white sand; they formed in the ice age, when the cave was dry.
The cave is named after an icon of the Madonna and Child that fishermen placed in a large opening above it to ask for protection from the dangers of the sea.
Practical: the cave lies at the tip of Capo Caccia, sheltered from the mistral, in Zone B of the Capo Caccia–Isola Piana AMP. Capo Galera calls the cavern a simple dive. On your own you pay the AMP €10 a day in 2026.

- Opening of ~20 m; max -18 m (it.wikipedia). Parts of the ceiling reach the surface. In front of the cave the 'Massi delle Gorgonie rosse' lie below -35 m (Portoconte).
