Aci Trezza stands on the coast, 1 mile SSW of Capo Molini. Most of the houses in the village are red in colour. The village includes a small fishing harbour. Anchorage can be obtained, in good weather, in the bay to the N between Capo Molini and Isole Ciclopi. The holding is good, but the bottom is rocky in some places; local knowledge is required. Caution: vessels should put to sea when heavy clouds hang about the crater of Monte Etna, for strong onshore winds may then be expected.
