The Capo Grillo dive begins on the northern slope of the ridge, which is characterised by a shallow seabed of alternating sand and pebbles. Following the wall to the right, you will come to a cave with a 3 m by 2 m wide triangular entrance at the depth of 18 m, which terminates in a chamber that is large enough to hold two divers. The dive continues descending along the side. At the depth of 40 m, you will find a second crevice in the ridge, which looks like a narrow vertical slot. Passing over the ridge, you will come to a landslide of large boulders from a landslide on the opposite side. After exploring the landslide and turning back in the direction from which you came, you will once again pass over the ridge, and will begin climbing northward along the slope until you reach the depth of 30 m. From this point, you will continue on to another series of large boulders.
