A focused private 90-minute cruise from Sperlonga into the Riviera di Ulisse to see Roman grottoes, medieval towers and limestone caves, with a half-hour swim break, snorkeling gear and pizza with prosecco on board. Ideal as a morning outing when the sea is calm.

The boat slips away from Sperlonga’s pier and the harbor noise thins to the hush of open water. Sun picks out the limestone cliffs as you cruise into the Riviera di Ulisse Regional Park; gulls wheel and the sea dares you to leave the deck for a dip. Within minutes the Grotta di Tiberio appears—an ocean-facing scar of Roman ambition—and the captain eases the bow close enough for a clear view of the villa remains carved into the rock.
