Ponza and the Pontine Islands by Boat: Palmarola, Ventotene and Zannone (2026)

The Pontine Islands lie off the coast between Rome and Naples, close enough for a weekend from the capital. Ponza is the hub, with a pastel harbour and pale tuff cliffs, sea stacks and caves. Palmarola, next door, is almost empty and has some of the most dramatic rock formations in Italian waters. Zannone belongs to the Circeo National Park, and Ventotene and Santo Stefano form a marine protected area with real rules. Here a good skipper matters: knowing which coves are open and which side is sheltered on the day.

Harbours and marinas: where boats leave from

You can sleep on Ponza and charter there, or charter a faster boat on the mainland and cross. Ferries and hydrofoils to Ponza run from Anzio, Terracina and Formia, with seasonal services from San Felice Circeo; most visitors leave the car on the mainland. Drive times are rough estimates.

• Ponza harbour: gozzi, charter boats and water taxis line the quay. Best for the most time on the water.
• San Felice Circeo: the marina below Monte Circeo is one of the closest mainland points to Ponza and Zannone. Roughly one and three quarter hours from central Rome. Best for a long day trip in a fast boat.
• Terracina: a working port with ferry links to Ponza, a similar drive from Rome. Best if you are also visiting Sperlonga.
• Formia: the main port for Ventotene as well as Ponza. Roughly one and a quarter hours from Naples airport and two hours from Rome. Best for Ventotene and Santo Stefano.
• Anzio: the closest port to Rome, around an hour from the city and Fiumicino in light traffic, but the longest crossing. Better for a ferry than a private day trip.

The best routes in detail

Times assume a fast motor boat or RIB in calm conditions. Confirm with your skipper.

Route 1: Ponza half day loop (3 to 4 hours, from Ponza harbour)

Head south past the Grotte di Pilato, rock cut chambers usually described as Roman fish ponds; ask whether boats may enter on the day. Round the southern tip to Chiaia di Luna, the crescent beach under a sheer white cliff. It is closed: after a fatal rockfall in 2001 and further landslides in 2015 and 2018, the beach and its Roman tunnel have stayed shut, and Italy’s official tourism site says it can only be admired from the sea at a safe distance. On the same western side, the Faraglioni di Lucia Rosa rise from the water. Finish at Cala Feola near Le Forna, whose natural rock pools are one of the few places on Ponza where bathing is allowed.

Lunch: back in the harbour, or near Cala Feola if your skipper can arrange a drop off.

Route 2: Palmarola full day (6 to 8 hours, from Ponza harbour)

Palmarola lies around 10 km west of Ponza, roughly 30 to 60 minutes away. Cala del Porto is the only landing point and real beach, with a few houses, cave dwellings cut into the tuff and one small restaurant. At the southern end, the Faraglioni di Mezzogiorno hold a large sea cave. The Cattedrale is a basalt wall split into fissures like Gothic arches. Our research turned up contradictory information on its position: one tourism source places it near Punta delle Brecce, another on the north coast near Cala Tramontana. It was not clear to us which is correct, so let the skipper plan the order. Ask too about La Forcina and the Grotta del Gatto, a narrow cave entered by small boat.

Lunch: ashore at Cala del Porto; book in summer.

Route 3: Zannone (half or full day, from Ponza or San Felice Circeo)

Zannone, about six nautical miles (11 km) north east of Ponza harbour, is part of the Circeo National Park and deserted apart from park staff. Boats land at the Approdo del Varo, near a Roman fish pond, and a woodland path passes the ruins of a Cistercian monastery to views over Ponza and Palmarola; mouflon live on the island. Italy’s official tourism site says visits are booked through the park office in Sabaudia.

Lunch: nothing is sold on Zannone. Bring a picnic or return to Ponza.

Route 4: Ventotene and Santo Stefano (full day, from Formia or Ponza)

Ventotene, about 2.8 km long, has a harbour cut by the Romans into the tuff and a small village for lunch. Santo Stefano, about a mile away, is crowned by a former Bourbon prison. Cala Nave, Parata Grande and Cala Rossano are the best known bays, but in summer they are marked bathing areas closed to boats, so you anchor in an authorised sector and swim in. The waters closest to Santo Stefano are closed to all boats. In July 2026 the government commissioner reported that safety works on the prison were complete but a secure landing was still to be built, so check with the harbour before planning a visit ashore.

Lunch: in Ventotene village, a short walk from the Roman harbour.

Route 5: Two or three days island hopping

With a cabin boat or small yacht: night one in Ponza harbour, day two around Palmarola, day three across to Ventotene, ending at Formia. Harbour berths fill fast in August.

Rules: protected areas, anchoring, fees and closures in 2026

Ventotene and Santo Stefano marine protected area

The 1997 founding decree creates three zones. In Zone A, around Santo Stefano, navigation, stopping and swimming are banned except for authorised research and guided dives. In Zone B, the decree bars motor boats within 500 metres of the coast except authorised services and guided visits. Anchoring is banned everywhere except in sectors marked by the managing body, and spearfishing is banned throughout.

A summary of the 2026 annual rules describes speed limits of 5 knots within 300 metres of the coast and 10 knots between 300 and 600 metres; bathing areas at Cala Nave, Parata Grande and Cala Rossano closed to boats from 1 May to 30 September; and anchoring in Zones B and C only with authorisation, in six designated sectors, never on Posidonia. Listed 2026 daily fees for non residents are 15 euros (Zone B) and 10 euros (Zone C) for a natante, the smallest category, and 25 and 20 euros for an imbarcazione. The decree and the 2026 summary describe Zone B access differently; our research could not settle which applies to which boat. Ask your skipper to arrange authorisation, and check with the reserve office in Ventotene.

Zannone and the Circeo National Park

Landing on Zannone is organised through the park. We could not find a current official rule on anchoring or swimming around the island, so check with the park and your skipper.

Ponza and Palmarola

Ponza and Palmarola are not a marine protected area, but Palmarola and Zannone form an EU Natura 2000 site whose conservation plan names uncontrolled boat access to caves as a threat. Most of Ponza’s free beaches are closed for rockfall risk; bathing is allowed at Cala Feola, the port area, part of Frontone and Palmarola. Never swim or land under unstable cliffs.

Coast Guard rules

Summer Coast Guard ordinances set minimum distances from beaches and cliffs and speed limits near the coast. We could not verify the 2026 figures for these waters, so check with the skipper or harbour office.

Types of boat and what a skippered charter includes

• Gozzo: Ponza’s traditional wooden boat, slow, stable and shaded. Ideal for Ponza and Palmarola.
• RIB: fast and agile for caves, but exposed. Good for Zannone and mainland crossings.
• Motor yacht or cabin cruiser: shade, a toilet and cabins for longer crossings or overnight trips.
• Sailing yacht: rewarding over two or three days, too slow for a day trip from the mainland.

A private skippered day usually includes the boat, skipper, insurance and basic kit such as snorkel masks. Fuel is often extra on fast motor boats and can be a large share of the cost on a mainland crossing. Lunch ashore, drinks, overnight berths and Ventotene reserve fees are normally extra. Get inclusions in writing.

Licence free hire: in Italy you may drive a boat without a licence if the engine is no more than 30 kW (40.8 hp), within cubic capacity limits, and you stay within 6 nautical miles of the coast.

Route comparison

Best months, winds and practical tips

The season runs roughly from May to early October. June and September balance warm water and space at anchor. August, especially around Ferragosto on 15 August, brings heavy traffic from Rome and Naples: crowded anchorages at Palmarola, full harbours and booked out restaurants. In August, start early and choose weekdays.

Wind decides the day. Ponza harbour is on the eastern side, so the western coast with Chiaia di Luna and Cala Feola is exposed to westerly and north westerly wind. Strong wind can cancel a Palmarola or Ventotene crossing, so keep a spare day.

• Bring: reef safe sun cream, a hat, a light layer for the return, water shoes, cash for lunch and a dry bag.
• Seasickness: take any remedy before boarding and sit near the stern.
• Booking: for July and August, book boat and lunch several weeks ahead; for June and September, a week or two usually suffices.

Where to stay near the harbours

Expect four star hotels rather than palaces. For more coastal bases, see the best yacht spots along the Tuscan coast and Porto Santo Stefano and Monte Argentario.

Grand Hotel Santa Domitilla, Ponza

Around 200 metres above Ponza harbour according to booking listings, with a free port shuttle. The garden holds several outdoor pools and a wellness area with a Turkish bath. Some pool and spa areas are seasonal and charged extra, so ask the hotel what is open on your dates.

Best for: walking straight to the boat.

Hotel Punta Rossa, San Felice Circeo

On the rocky coast below Monte Circeo, a short drive from the town and marina (ask the hotel for transfer times). Listings describe indoor and outdoor pools, a spa, private sea access by steps cut into the rock, and a restaurant with a pool bar.

Best for: a spa stay with a long day at sea.

Check rates at Hotel Punta Rossa

Grande Albergo Miramare, Formia

A four star hotel on the Via Appia, about 2.5 km by car from the port of Formia, with a garden, private beach, a seasonal pool (listed as June to September) and two restaurants. There is no spa, and some guests report beach and pool closed outside high summer, so ask the hotel for shoulder season dates.

Best for: early departures to Ventotene.

Frequently Asked Questions

Can you visit Chiaia di Luna in 2026?

Only from the sea, at a safe distance. The beach has been closed since a fatal rockfall in 2001.

Can you do Ponza as a day trip from Rome?

Yes, by ferry from Anzio or a private boat from San Felice Circeo, but it is a long day. One or two nights on Ponza is far more relaxed.

Do I need a permit to anchor at Ventotene?

Yes. Anchoring is only allowed in designated sectors with authorisation and a daily fee, and zone A off Santo Stefano is closed to boats, although the 2026 rules also list one authorised anchoring sector off the island, so check the limits with your skipper.

Can I hire a boat without a licence on Ponza?

Yes, with an engine up to 30 kW (40.8 hp) and within 6 nautical miles of the coast. Take a skipper for longer crossings.
