This dive begins in the channel between Vulcano and the Quaglietto rock outcropping, where the seabed ends on the sand at a depth of 15 m. The most interesting part of this itinerary is the western wall, which can be accessed from both the right and the left. From the anchoring point, you will quickly reach the depth of 30 metres.

Heading back up a few metres and continuing to circumnavigate the rock, you will come to the large opening of the Grotta dei Gamberi (the “Shrimp Cave”), which is better known as the Grotta della Madonnina (the “Cave of the Virgin Mary”) due to the nearly one-metre high statue resting on its floor. The cave is shaped like an inverted “V”, with the summit at a depth of 18 m, and the floor at a depth of 26 m. It extends into the rock for about twenty metres. In front of the large cave, and next to the rocks scattered along the bottom, lies a large anchor embedded in the sand, with only the upper part of the shank visible.
