Tremiti Islands: San Nicola, the Medieval Abbey and the Adriatic You Never Expected

The Tremiti, the Adriatic's forgotten archipelago

When you think of Puglia's sea, Salento comes to mind, Polignano, the Maldives of the South. Almost nobody thinks of the Tremiti, yet this tiny archipelago 22 kilometres from the Gargano harbours some of the finest seabeds in the Adriatic and a historical heritage stretching from the Romans to the Bourbons.

The islands are five: San Domino (the largest, with beaches), San Nicola (the fortified historic centre), Capraia (uninhabited, the wildest), Pianosa (a strict nature reserve, inaccessible) and the Cretaccio (a sea stack). Together they form the Tremiti Islands Marine Nature Reserve, established in 1989.

Getting there

Ferries and hydrofoils depart from several ports:

• From Termoli (Molise) — the most frequent connection. Tirrenia/NLG hydrofoils in approximately 50 minutes, ferries in approximately 1 hour 45. Up to 4–5 sailings a day in summer.
• From Vieste (Gargano) — hydrofoils in approximately 1 hour 30, seasonal (June–September).
• From Rodi Garganico and Peschici — less frequent summer connections.

By helicopter from Foggia (Alidaunia, 20 minutes): striking but expensive. Cars cannot be disembarked: the islands are pedestrian and distances are minimal.

San Nicola: the fortress-borgo

San Nicola is the historic heart of the Tremiti. The entire island, barely more than a kilometre long, is occupied by a fortified complex that seems to have stepped out of a medieval film. The main monument is the Abbey of Santa Maria a Mare, founded in the ninth century by the Benedictines of Montecassino, rebuilt in 1045 and extended by the Cistercians and Lateranenses in subsequent centuries.

The church preserves an eleventh-century mosaic floor, a medieval wooden crucifix and a Byzantine panel of the Virgin. The cloister, the defensive walls and the towers attest to the military function the island has played for centuries: from Saracen pirates to Bourbon deportations, to Fascist internment.

The island's cemetery, overlooking the cliffs, is one of the most evocative in Italy.

San Domino: beaches and pine forest

San Domino is the island for seaside holidays. Covered by a forest of Aleppo pines — the most extensive in the Adriatic — it offers rocky coves with crystal-clear water:

• Cala delle Arene — the only sandy beach in the archipelago, small and very busy in August.
• Cala degli Inglesi — a flat rocky shore ideal for diving and snorkelling.
• Cala Matano — a sheltered cove in the pine forest, reachable via a short trail.
• Grotta del Bue Marino — the most spectacular sea cave, visitable by boat. The name recalls the monk seal that once lived here.

The island boat tour (approximately 1 hour, €15–20) is the best way to discover the caves and coves inaccessible from land.

Diving and snorkelling

The Marine Reserve protects seabeds of exceptional clarity. The most celebrated dive sites:

• Secca di Punta Secca — vertical walls with gorgonians, sponges and nudibranchs.
• Relitto del Lombardo — a steamship from 1879 resting on a sandy bottom at 15 metres. One of the most accessible wreck dives in Italy.
• Capraia — the uninhabited island offers the most intact seabeds, with large groupers, lobsters and posidonia meadows.

Snorkelling is excellent throughout: average visibility exceeds 30 metres and in summer water temperature reaches 25–26 degrees.

Where to sleep and eat

Accommodation is concentrated on San Domino: hotels, self-catering apartments, B&Bs and a campsite in the pine forest. San Nicola has very few facilities. Booking months in advance for July and August is essential.

The cuisine is a reimagined Adriatic: Tremiti-style fish stew, spaghetti with sea urchins (when harvesting is permitted), mussels marinara, grilled fish. The wild capers of the Tremiti are a little-known local excellence.

When to go

The ideal months are May, June, September and the first half of October. In spring the archipelago is deserted and in flower; in autumn the sea is still warm and Adriatic sunsets are spectacular. August is lively but manageable, far less chaotic than the major Puglian seaside resorts on the mainland.

Practical tips

• Bring comfortable shoes for the paths and stairways of San Nicola
• Mask and snorkel are essential: the sea is the protagonist
• Book the boat tour early in the morning to avoid the afternoon wind
• Bring cash: not all businesses accept cards
• Respect the strict reserve zones: the fine is hefty

Evening between the islands

The sunset seen from the terrace of the Abbey of San Nicola is one of the most intense spectacles in the Adriatic. The sun drops behind the dark outline of San Domino, and the sea turns pink and gold. The church bells strike six, herring gulls glide over the walls and the air fills with the scent of Aleppo pines drifting from the neighbouring island.

After dinner, a walk along the pine forest trails of San Domino is a unique sensory experience: the scent of resin, the chirping of crickets, the glow of the moon on the water. In an archipelago without nightclubs or late-night bars, the evening belongs to nature and silence. Stars are visible with a clarity rarely found on the coast, and on moonless nights the Punta del Diamante of Capraia can only be guessed at by the absence of lights.

The Tremiti are the Adriatic's exception: an archipelago that looks like Greece or Croatia but is Puglia, less than an hour from the coast. For those in search of an Italian sea without the crowds of the major destinations, it is one of the most compelling answers.
