Book a Pompeii day trip with a difference, and travel to the ancient archaeological site by boat from Sorrento. After cruising from Piano di Sorrento to Castellammare di Stabia near Naples, you’ll take a bus to Pompeii for a guided tour of the UNESCO-listed archaeological digs. Continue to the nearby Cellini Gallery to admire its cameo gems and corals, then gaze at the Bay of Naples from Mt. Vesuvius. Bring your bathing suit as there’s one last stop for a cool-down swim on the way back to Sorrento. Entrance fees are at your own expense.
