Pontine Islands by boat: Ponza and Ventotene from Rome

The Pontine Islands are the closest island group to Rome that feels truly remote: volcanic cliffs, sea caves and crystal-clear water. A week from Marina di Nettuno combines the Circeo headland and the old harbours of Sperlonga and Gaeta with three island days: Ventotene and its marine reserve, Ponza's lively harbour, and uninhabited Palmarola and Zannone. Expect open-water crossings of 20 to 35 nautical miles.

Where to charter a yacht for the Pontine Islands?

The nearest base is Marina di Nettuno, the harbour listed as Rome on Ship O'Hoi, an hour south of the city. You can compare it with other bases on the yacht charter in Italy page. Charter weeks usually run Saturday to Saturday. For a bareboat charter you need a licence the charter company accepts (see boat licence in Italy and the ICC); otherwise book a skipper or a crewed yacht.

A 7-day sailing itinerary from Marina di Nettuno

You usually take over the yacht on Saturday afternoon and sleep aboard in the marina. The loop runs down the coast first and then out to the islands, so the last day is a short coastal leg. Distances are rough estimates; plan every leg with current charts and a pilot book, and check the forecast each morning, as the crossings offer no shelter.

Day 1: Marina di Nettuno – San Felice Circeo (approx. 25 nm)

Anzio, the neighbouring town just west of the marina and the birthplace of Nero and Caligula, is worth a morning walk before you cast off. Then head south-east along the long sandy coast to Monte Circeo. The limestone promontory rises 541 metres out of the plain, and its seaward slope has many caves, including Grotta Guattari, where a Neanderthal skull was found in 1939. The headland is the symbol of the Parco Nazionale del Circeo, and you see it best from the sea. Overnight in the harbour of San Felice Circeo on the east side of the headland. The mooring cooperative there answers on VHF channel 9.

Tip: call the harbour ahead in summer, as transit berths are limited.

Day 2: San Felice Circeo – Sperlonga – Gaeta (approx. 25 nm)

Sail east along the Riviera di Ulisse to Sperlonga, where Emperor Tiberius built his seaside villa. Stop for lunch at anchor off the beach, outside the bathing zone. Then continue round the Monte Orlando headland into the Gulf of Gaeta. Overnight in a Gaeta marina, for example Base Nautica Flavio Gioia on the waterfront. Book ahead in July and August.

Tip: in the Gaeta maritime district, which also covers Sperlonga, the sea within 200 m of beaches and 100 m of steep coast is reserved for swimmers during the bathing season. No boats may pass, stop, moor or anchor there.

Day 3: Gaeta – Ventotene and Santo Stefano (approx. 26 nm)

This is the first open crossing, south-west to Ventotene. The island has two harbours: the ancient Porto Romano and the newer Porto Nuovo at Cala Rossano, where the ferries also dock. Alternatively, anchor in one of the reserve's designated anchoring areas, which needs an AMP permit (see the rules below). In the afternoon, motor slowly the one nautical mile or so across to Santo Stefano to see the former Bourbon prison.

Tip: get your anchoring or mooring permit before you arrive, through the reserve's BlueDiscovery app or the PagoPA payment link on riservaventotene.it.

Day 4: Ventotene – Ponza (approx. 22 nm)

Head north-west to Ponza's Bourbon harbour below the pastel houses of the old town. Private floating pontoons take yachts up to around 24 m, with water, power and a night watchman. The Grotte di Pilato, Roman moray-eel ponds cut into the rock, lie on the south side of the harbour; explore them by dinghy.

Tip: reserve a pontoon berth ahead in high season. The local Guardia Costiera office (Circomare Ponza) listens on VHF 16 from 08:00 to 20:00.

Day 5: Ponza – Chiaia di Luna – Palmarola – Zannone – San Felice Circeo (approx. 34 nm)

This is the long highlight day. Leave early and round the south tip of Ponza to the west coast and Chiaia di Luna, the crescent beach under a sheer tuff cliff. It is best seen from the water: the beach has been closed to the public for years because of rockfall from the cliff. Then cross about 5 nm to Palmarola, which is uninhabited. Its only landing place is Cala di San Silverio, and its best-known sights are the rock formations called the Cattedrali and the Faraglione di Mezzogiorno. Swim, then sail about 9 nm east to green, uninhabited Zannone, part of the Parco Nazionale del Circeo since 1979 and a stop for thousands of migrating birds; the only landing is at Punta del Varo. From Zannone it is about 15 nm back to San Felice Circeo for the night.

Tip: if the forecast is poor, split this day. Spend a second night in Ponza and visit Palmarola as a day trip (a little over 7 nm each way). The next day, sail back to Circeo via Zannone (about 21 nm).

Day 6: San Felice Circeo – Marina di Nettuno (approx. 25 nm)

A final coastal leg takes you back to Nettuno. Charter contracts usually ask you to be back in base on Friday afternoon or evening for check-out and refuelling; check the exact time. Disembark on Saturday morning.

Rules and safety in the Pontine Islands

Ventotene and Santo Stefano marine protected area

The waters around Ventotene and Santo Stefano form the Area Marina Protetta Isole di Ventotene e Santo Stefano, which the Comune di Ventotene manages. Its regulation (ministerial decree of 18 April 2014) and the reserve's supplementary rules set out three zones:

• Zone A (strict reserve): no navigation and no anchoring.
• Zone B: sailing yachts, rowing boats and electric boats may navigate. Motor boats may only go closer than 500 m to the coast to reach the official mooring buoys, and only with a permit. Beyond 500 m they must meet eco requirements (a compliant engine, or holding tanks for black and bilge water).
• Zone C: navigation is open to recreational boats.
• Speed limits in zones B and C: maximum 5 knots within 300 m of the coast and 10 knots between 300 and 600 m, always in displacement mode.
• Anchoring is only allowed with a permit and only on sand or pebbles. It is banned on Posidonia oceanica seagrass and coralligenous reef. The reserve has marked specific anchoring areas (for example Parata Grande–Pascone, Punta dell'Arco, off Santo Stefano and Punta Eolo), and a zone B permit also covers zone C. A fee applies (daily, weekly or longer). Check the current amount on the reserve's permits page.
• Mooring buoy fields: you need a permit, must use a buoy for your size category, keep the engine off while moored and swim only next to your own boat. Anchoring inside the buoy fields is banned.
• Bathing areas: from 1 May to 30 September, buoys mark the bathing areas at Cala Nave, Parata Grande and Cala Rossano. Boats may not enter, moor or anchor inside them.
• Discharges: you may not discharge untreated bilge water, black water or any waste.

The full texts are on the reserve's rules page.

Circeo, Zannone and Palmarola

The Parco Nazionale del Circeo protects the headland, the coastal lakes and the island of Zannone. The seabed around Zannone and between Capo Circeo and Terracina is also protected, as special areas of conservation in the EU Natura 2000 network. Anchor on sand, never on seagrass, and follow the park's own guidance on Zannone. The islands of Palmarola and Zannone together form another Natura 2000 site.

Guardia Costiera rules

In the bathing season the Guardia Costiera reserves the sea within 200 m of beaches and 50 m of rocky shores on Ponza and Ventotene (200 m and 100 m on the Gaeta coast) for swimmers: no boat may pass, stop, moor or anchor there. If you swim from your boat, fly the red flag with a white stripe. The ordinances are reissued each spring on guardiacostiera.gov.it. Maritime emergency number: 1530.

Licence

Without a licence you may only drive boats with engines up to 30 kW (40.8 hp) within 6 nm of the coast (see boat licence in Italy). The island crossings go well beyond 6 nm and charter yachts have bigger engines, so the skipper needs a licence the charter company accepts, such as the ICC, or you hire a skipper.

Best time to sail the Pontine Islands

The sailing season runs roughly from May to October. The lifeguarded bathing season here runs from the third Saturday in May to the third Sunday in September. July and August are the warmest and busiest months, and the harbours of Ponza and Ventotene fill up, especially around Ferragosto (15 August), Italy's big summer holiday. June and September bring quieter harbours. Keep a spare day for bad weather before the open crossings.

FAQ

How far are the Pontine Islands from Rome by boat?

From Marina di Nettuno, Ponza is about 36 nm in a straight line. Most crews break the trip at San Felice Circeo (about 25 nm), from where Ponza is about 20 nm.

Can I land on Chiaia di Luna beach?

Plan to see it from your boat. The beach has been closed for years because of rockfall from the cliff above, and the sea in front of it is a bathing zone in summer.

Can I stop at Zannone and Palmarola?

Yes, for a daytime swim and a look. On Zannone you can only land at Punta del Varo, and on Palmarola at Cala di San Silverio. Both islands are uninhabited, so bring everything you need.

Is one week enough for the Pontine Islands?

Yes, for all four islands plus the Circeo and Gaeta coast, with two long days. With ten days or more you can continue to the Bay of Naples.
