Ustica San Paolo cove  is located in the southern part of the island, in the Zona C of the Ustica Island Protected Marina Area, and is one of the few coves that can also be reached from land along the long Mezzogiorno Trail which starts from the town and reaches the Cavazzi Lighthouse Point. Some flat rocks on which to lie down but so much beauty in this cove set in the middle of the lush green of the Mediterranean scrub that reaches almost to the sea. On the right we find the promontory of San Paolo Point, where we can go to visit the  Za Maruzza cave, reachable by following the signs that we find along the path, while on the coast of the promontory it is easy to notice, when you are by boat, the singular Bull Rock. On the left of the bay, about a hundred meters away, we find the splendid Boats Cave, a must to visit after a short swim. San Paolo cove is a quiet place, easily reachable after about 20 minutes on the Mezzogiorno trail, ideal for long swims, snorkeling, diving destination for the beauty of scuba diving, and during the high season, for many boats that stop there undisturbed.
