Depth: -9 / -21 mt.
Dive time: 60 min.
Already at 9 mts depth the dive start with the top of the cliff linked to the arch, and descending along the cliff’ face at 18 mt a spectacle of nature is revealed: the all arch can be admired on its entirety, with the sun light that filtering on it makes amazing play of light. This area is characterized from the richness of wildlife. The Sant’Irene is a wide shallow: other than the natural arch there are 9 more dive points, that together with the friend and collaborator Leonardo D’Orrico can be explored.
