The Tremiti Islands and the Gargano by Boat (2026)

The Gargano, the spur of Italy’s boot, is a limestone promontory in northern Puglia where white cliffs drop into clear water, riddled with sea caves, arches and stacks. About 12 miles offshore lie the Tremiti Islands, the only Italian archipelago in the Adriatic, all inside a marine reserve with detailed 2026 rules. That makes for two very different boat days: a cave tour south of Vieste, and a crossing to the islands, where the buoy fields and closed zones matter as much as the weather.

Harbours and marinas: where boats leave from

Ferries reach the Tremiti from Termoli year round and from Vieste, Rodi Garganico, Peschici and Manfredonia seasonally, broadly late spring to September. Depending on the route, boats arrive at San Domino or San Nicola, linked by a short shuttle. Drive times are rough estimates.

• Vieste: the main hub for private boats and cave tours, with the widest choice of hotels. Roughly two and a half to three hours by car from Bari airport. Best for the cave coast; the Tremiti are around 33 nautical miles away.
• Peschici: a white clifftop town with a small harbour, between Vieste and Rodi. Best for a quieter base within reach of both.
• Rodi Garganico: on the northern shore, one of the closest Gargano ports to the islands; our research turned up contradictory information on the crossing time, with listings giving anything from about 50 minutes to 1 hour 15 minutes, so confirm with the ferry operator. Best for a Tremiti day.
• Termoli: in Molise, off the A14 motorway, about 23 nautical miles from the islands. Best if you arrive from the north.

The best routes in detail

Times assume a fast motor boat in calm water; confirm with your skipper.

Route 1: Vieste cave coast, half day (3 to 4 hours, from Vieste)

Head south past Pizzomunno, a limestone monolith about 25 metres tall on the beach outside town. The coast towards Mattinata is lined with sea caves: Grotta Campana, shaped like a bell; Grotta dei Due Occhi, with two openings worn by the waves; Grotta Smeralda, known for its green water; and Grotta Sfondata, whose roof has collapsed. About 8 km from Vieste, the Architiello di San Felice, a natural arch, frames a small golden sand bay below a watchtower. Whether you go inside a cave depends on swell and local rules: the skipper’s call.

Lunch: back in Vieste.

Route 2: Vieste to the Baia delle Zagare, full day (6 to 7 hours, from Vieste)

Take Route 1 slowly, with swim stops between caves, and continue to the Baia delle Zagare near Mattinata, where white stacks rise from clear water below the cliffs. Good for anyone who prefers to stay close to shore.

Lunch: ashore near the Baia delle Zagare, where tourism sources point to restaurants with views over the bay; ask the skipper which accept arrivals by boat.

Route 3: The Tremiti Islands, full day (7 to 9 hours, from Rodi Garganico, Peschici or Termoli)

Cross to San Domino, the largest island, covered in Aleppo pine. Cruise its coast past the Grotta del Bue Marino, the Grotta delle Viole near the Pagliai stacks and the Scoglio dell’Elefante; private motor boats may not enter the caves, so view them from outside. Take a buoy at Cala delle Arene, the only sandy beach, behind the port, or in the channel between San Nicola and Cretaccio, the small islet between the two. Ashore, take the shuttle to San Nicola and walk up to the fortified abbey of Santa Maria a Mare. Capraia, to the north, has buoys on its eastern side. Pianosa, set apart, is Zone A and closed to boats.

Lunch: ashore on San Domino, around the main square.

Route 4: Vieste to the Tremiti (full day, long)

Around 33 nautical miles each way, so much of the day is transit and a northerly swell makes it hard work. From a Vieste base, driving to Rodi Garganico or Peschici is usually better.

Route 5: Two or three days on the water

With a cabin boat: the cave coast from Vieste, then north past Peschici and across to the Tremiti, then around the islands before ending at Rodi or Termoli. The 2026 buoy rules set a tariff day from 10:00 to 10:00 and require an all round white anchor light at night, which suggests overnight stays are possible, but they also forbid living aboard or using a buoy as a residence. Confirm overnight options with the reserve or harbour.

Rules: marine reserve, park, buoys and fees in 2026

The Tremiti marine reserve, created by a 1989 decree and managed by the Gargano National Park, covers the waters around the islands broadly out to the 70 metre depth line. The rules below come from the park’s provisional regulation for 2026.

Zones

• Zone A, around Pianosa: no navigation, mooring, anchoring, bathing, diving or fishing, except authorised research and surveillance.
• Zone B, the outer side of Capraia and a stretch of San Domino: motor navigation only with authorisation; sail, oar and electric craft may enter freely. Bathing is allowed.
• Zone C, the remaining waters: motor navigation is free, subject to Coast Guard ordinances.

Speed limits and caves

Zone B: 5 knots. Zone C: 5 knots within 300 metres of the coast, 10 knots between 300 and 600 metres. Jet skis and towed sports are banned. Motor pleasure boats and hired or chartered boats may not enter sea caves; only park authorised boats may, through marked corridors.

Anchoring and mooring buoys

Anchoring is allowed only on sand or pebble bottoms in Zone C. The park runs 160 buoys from 1 May to 30 September 2026, at the San Nicola and Cretaccio channel, Cala delle Arene, Cala Spido, the Scoglio dell’Elefante, the Grotta del Sale, the Pagliai and Capraia’s east side. Buoys may be used only up to force 4 (16 knots) and 2.5 metre waves. One boat per buoy, approach at 3 knots or less, carry third party insurance. Bathing is not allowed in the buoy fields, so swim at anchor in Zone C or from the beach.

Fees

Buoys must be paid before use through PagoPA on the park website; card terminals on site are the fallback if PagoPA fails, there is no cash and no refunds. Published 2026 daily rates for non residents with a boat up to 8 metres are 20 euros Monday to Thursday in May, 30 euros Monday to Thursday in June and September, 40 euros in July and 60 euros any day in August (up to 15 metres: 35, 45, 55 and 80 euros), more from Friday to Sunday. Zone B motor navigation needs an authorisation: 10 euros a day plus a 10 euro administrative fee. Fines run from 300 to 1,032 euros. Ask your skipper whether the islands’ visitor landing contribution applies to private boats.

The Gargano coast and the national park

The mainland cave coast is not part of the marine reserve. Boats there follow the summer Coast Guard ordinance on distances from beaches and speed near shore; we could not verify the 2026 figures, so check with the skipper or harbour office.

Types of boat and what a skippered charter includes

• Gozzo or open motor boat: slow and stable. Ideal for the cave coast.
• RIB: fast for the Tremiti crossing, but exposed.
• Motor yacht or cabin cruiser: shade, a toilet and cabins for the islands or several days.
• Sailing yacht: rewarding over several days, too slow for a day trip.

A private skippered day usually includes boat, skipper, insurance and snorkel kit. Fuel is often extra on fast boats and weighs heavily on a Tremiti crossing. Lunch, drinks, buoy fees and berths are normally extra. Ask whether the skipper holds a Zone B authorisation, and get inclusions in writing.

Licence free hire: in Italy you may drive without a licence with an engine up to 40.8 hp (30 kW) within 6 nautical miles of the coast. Fine for the cave coast; take a skipper for the Tremiti.

Route comparison

Best months, winds and practical tips

The season runs broadly from May to September. June and September bring warm water, space at the buoys and lower rates. In August fees peak and the islands fill with day visitors, especially around Ferragosto on 15 August: start early and choose weekdays.

The shallow Adriatic builds a short, steep sea quickly. Northerly winds make the crossing uncomfortable and buoys close above force 4, so keep a spare day for the islands.

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

Where to stay near the harbours

Expect seasonal resorts rather than palaces; most close outside summer. For the rest of the region, see our Puglia guide and, for a palace stay further south, the Borgo Egnazia review.
