The Experience

The boat leaves Anzio and heads to Ponza, a volcanic island off the Italian coast where the itinerary circles the shoreline with stops timed for swimming. You'll drop anchor at five different points—Pilate's Grottoes, the white volcanic-ash cliff, the Natural Pools carved into rock, Felci Cove with its sulphur-yellow walls, and the Natural Arch, a sea stack hollowed through the center. Between swims, the guide describes what you're passing: remnants of a Roman aqueduct that once supplied the island's water, a WWII landing ship that sank offshore, and the closed mine that shifted Ponza's economy toward fishing and tourism. Bring your own snorkeling gear or use what's available on board.

Lunch arrives mid-day—pasta and an aperitif, plus wine, water, snacks, fruit and espresso. The final stop is Frontone Beach, the island's most popular strand, before the boat returns to port. The whole day runs six hours. Sea conditions determine whether you can swim through the grotto at the white cliff or access every planned stop; the guide adjusts the route as needed.

If you're departing from Anzio rather than already on Ponza, select the ferry-ticket option at checkout and meet the group at Anzio port. Children must be accompanied by an adult, and you need to be a swimmer to join the water stops. Bring a towel and sunscreen.

Top questions

What are the Pilate's Grottoes and why is that the first swimming stop?

Pilate's Grottoes are sea caves named after Pontius Pilate and serve as the opening swim stop on the itinerary, introducing you to the island's dramatic coastal geology and giving the group a chance to enter the water early in the day.

Can I swim through the grotto at the white volcanic-ash cliff?

The white cliff has a long grotto running straight through it, and at noon the sun creates blue reflections inside the water. Whether you can swim through it end to end depends on sea conditions that day—your guide will assess and invite adventurous swimmers if it's safe.

Is snorkeling gear provided, or do I need to bring my own?

Snorkeling gear is available on board, but you're welcome to bring your own. You must be a swimmer to participate in any of the swimming and snorkeling stops.

What's included in the onboard lunch?

Lunch includes pasta and an aperitif served on board, plus wine, water, snacks, fruit and espresso coffee throughout the day.

Do I need to book ferry tickets from Anzio separately, or are they included?

Ferry tickets from Anzio are optional—select the "Ferry Tickets Included" option at checkout if you're starting from Anzio, and meet the group directly at Anzio port. If you're already on Ponza, book the departure option that starts there instead.

What happens if the weather is bad on the day of the tour?

The exact itinerary and departure time may vary according to sea and weather conditions. The guide adjusts which stops are accessible, but the tour operates as long as conditions allow safe travel and swimming.
