Islands

The Tremiti Islands are a small Italian archipelago in the Adriatic Sea, off the Gargano Peninsula in Apulia. Travelers come for very clear water, snorkeling, coastal cliffs and the medieval abbey on one island.

Address: Tremiti Islands, Province of Foggia, Apulia, Italy

The Tremiti Islands sit about 16 km offshore from the Gargano Peninsula and form a comune in Italy’s Province of Foggia; they are also part of the Gargano national park. The archipelago is made up of five main islands - San Domino, San Nicola, Capraia, Cretaccio and Pianosa - with most services and accommodation concentrated on the largest inhabited islands. The region is noted for its clear, blue Adriatic waters and rocky coastline.

The islands have a long history: inhabited since the late Iron Age, they were the site of a Benedictine abbey in the Middle Ages and later used at various times as a place of confinement, including under Roman and 20th-century regimes. Remains of the monastery and coastal fortifications remain visible on San Nicola and record the islands’ strategic and ecclesiastical past. Over centuries the islands also hosted seasonal fishing communities and later modest tourism development.

Visiting feels compact and maritime: narrow lanes, small harbors and sea-accessible coves dominate the experience, with swimming and boat trips the main activities. San Domino offers the only sand beach in the group and is the most developed for visitors, while Capraia and Pianosa are essentially uninhabited. Expect basic local services in summer and a much quieter, pared-down atmosphere outside the high season.

  • San Domino beaches: The largest island with the only sandy beach in the archipelago, popular for swimming and easy water access.
  • San Nicola abbey and fortifications: Medieval monastery ruins, old cisterns and fortifications give a sense of the islands’ long religious and defensive history.
  • Snorkeling and clear-water reefs: The surrounding sea is unusually clear for the Adriatic, offering good snorkeling around rocky reefs and submerged features.
  • Boat trips around cliffs and caves: Short boat excursions reveal sea cliffs, grottoes and viewpoints that are otherwise inaccessible from shore.
  • Quiet islets - Capraia and Pianosa: These small, largely uninhabited islands are notable from the boat for their solitude and coastal geology.

Getting There & Around

How to Get to Tremiti Islands#

The nearest provincial city is Foggia; regional airports with wider connections include Bari and Pescara, each requiring onward road or rail travel to coastal ports. Main passenger ferry and hydrofoil services run to the Tremiti Islands from several Gargano and Molise ports on the mainland.

Regular departures to the archipelago operate from Termoli, Vieste, Rodi Garganico and Capoiale by ferry or hydrofoil; in summer frequency increases and private boats are common. There is also a small heliport on San Domino served by occasional flights; check operators and seasonal schedules and expect the last stretch to be by ferry, hydrofoil or private boat.

Tips for Visiting Tremiti Islands#

  • Services, shops and accommodation are concentrated on San Domino and San Nicola, so plan supplies accordingly if visiting other islets.
  • Ferry and hydrofoil timetables change seasonally and fill quickly in July and August, so book in advance or arrive early at the port.
  • Carry cash and basic supplies, particularly outside high season when some businesses close or reduce hours.
  • Respect that the islands are part of a national park and marine-protected areas - follow local rules about anchoring, fishing and access to sensitive sites.
