Along the sun-washed stretch of coastline between Sperlonga and Gaeta, the Riviera d'Ulisse unfolds as a compact parade of cliffs, caves and classical ruins. This private 4.5-hour boat tour from Sperlonga to Gaeta delivers three swim stops, guided natural history, and close-up views of sites such as the Grotta di Tiberio, the Grotta Azzurra and Gaeta’s Montagna Spaccata. Meet your group at Porto di Sperlonga (Via del Porto, 3) fifteen minutes before departure. From there the skipper eases out past the low harbor into clear Tyrrhenian water. The first stretch skirts the ancient via Flacca, a coastal Roman route, where limestone sea cliffs reveal medieval watchtowers and fissured grottoes. Guides point out the archaeological remains near the Grotta di Tiberio, where sculptures and the vestiges of an imperial villa recall Emperor Tiberius’s ties to the shore. Sea caves dominate the itinerary. The Grotta Azzurra is a shallow, light-filled bay ideal for a thirty-minute swim or snorkel among Posidonia meadows and small reef fish. The Grotta del Turco and other hollowed caverns punctuate the route with dramatic openings carved by wave action. Your guide times visits for calm water and safe entry; life jackets and snorkeling masks are provided on board. Approaching Gaeta, the Montagna Spaccata slices the skyline—its cleft shelters the Santuario della S.S. Trinità and offers a geological spectacle of fissured limestone. The Pozzo del Diavolo, inside the Monte Orlando marine protected area, presents a unique rounded cavity that invites a final dip in protected waters. Along the way expect to see gulls, cormorants and occasional dolphins hunting beyond the shallows. This excursion is private to your party, meaning space to relax on shaded benches, a ladder for easy water access, a freshwater rinse, and an onboard aperitivo: a slice of pizza and a glass of prosecco to toast the afternoon. The company supplies noodles and basic flotation aids; bring your towel, sunscreen and a change of clothes. Boats currently lack wheelchair ramps, though staff offer assisted boarding when possible. Practical notes: cancellation is free up to 24 hours before departure; the tour runs only in suitable weather. Group size caps at 12. The route blends natural spectacle—limestone cliffs, sea caves, Posidonia beds—with historical notes on Roman occupation and medieval coastal defenses, making it a compact, effortless way to experience the Riviera d'Ulisse. For travelers who want private access to blue caves, calm snorkeling and a local guide who folds legend into landscape, this Sperlonga-to-Gaeta cruise is an ideal half-day choice. Booking is straightforward via the operator's online reservation; show your confirmation at the Porto di Sperlonga desk and arrive ready to swim — this half-day promises a concentrated taste of Lazio's coastal geology, marine life and seaside history today.
