The morphology of the coastline and seabed consists of an imposing rocky outcropping that creates a natural wall in the underwater environment. The Basiluzzo underwater itinerary begins at the base of this block, at a depth of about 12 m. Following the guiding rope, which indicates the pathway, you will come to the base of the ridge. Heading southward, at a depth of about 15 m, you will have the chance to glide over a sandy hollow intermittently colonised by small banks of sea grass, until you come to the plateau. Returning along the guiding rope, the seabed rises in large steps as you overcome a series of big isolated rocks. At the depth of 6.7 m, you will encounter a submerged wall structure.
