San Domino is the largest of the Tremiti Islands, the only one with a proper forest, and the only one with real beaches. It measures 2.08 km², is entirely hilly (the high point, Monte Aria, reaches 116 m above sea level) and is blanketed in a dense canopy of Aleppo pines, junipers and mastic shrubs. Around 95% of the archipelago’s accommodation is concentrated here: hotels, B&Bs, residences, restaurants, RIB hire and dive centres are all on San Domino.
Geography and orientation
The island is shaped like a kidney elongated north to south. San Domino harbour, on the eastern flank, is where ferries and hydrofoils dock. A scenic road climbs from there to the village centre — a small cluster of houses, hotels and restaurants gathered around Piazza Belvedere — and continues out to the coastal spots: Cala Matano to the east, Cala delle Arene to the north-east, Cala dei Benedettini to the north-west, Punta Secca to the south, and Punta del Diamante to the west.
The only motorised transport is a panoramic tourist train (€10 a ride) that links the harbour to the village and to Cala Matano. Otherwise you walk: the village is fifteen minutes end to end, the coastal loop around the island takes two hours.
Beaches and coves
San Domino is the only island in the archipelago with beaches open to the public. The main ones:
- Cala delle Arene — the only sandy beach in the archipelago, on the north-east coast. Reached on foot from the harbour in 20 minutes (a 220-step staircase) or by boat. Shallow sandy seabed, perfect for families with young children.
- Cala Matano — a white-pebble and shingle beach on the east side, ten minutes on foot from the village. Small lido with sunbeds and umbrellas in summer.
- Cala dei Benedettini — an isolated cove on the north-west flank, reachable only by sea or via a rough path. Transparent water, no services.
- Cala dell’Architiello — the cove under the rock arch of the Architiello, the island’s geological emblem. Reachable by RIB or kayak.
- Cala degli Inglesi — on the south-west side, at the foot of the forest campsite. Pebble beach with deep water close to shore.
The coastal path
The loop trail that traces the entire San Domino coast is one of the most rewarding walks in the archipelago. It runs around 4 km, takes 1h30-2h at a tourist pace, has remarkable panoramic stretches and threads through the Aleppo pine forest. The easiest start is Piazza Belvedere; the recommended direction is anticlockwise (toward Punta del Diamante before sunset, to catch the best light on the Pagliai sea stacks).
Main waypoints along the path: Punta del Diamante (view onto the Pagliai stacks and the sunset), Cala dei Benedettini (panoramic rest stop), the Architiello (the symbolic rock arch), Cala delle Arene (optional 220-step descent), and Punta Secca (rated by Italian diving press as one of the country’s top dive sites).
The underwater Padre Pio
At Punta Secca, on San Domino’s southern flank, a bronze statue of Padre Pio was placed in 1998 at a depth of 14 metres. It draws devotional and photographic dives, accessible through the island’s two centres (Tremiti Diving Center and Marlin Diving). The dive is straightforward, open even to certified Open Water divers.
Pine forest and wildlife
San Domino’s pine forest covers around 70% of the island and is dominated by Aleppo pines (Pinus halepensis), a Mediterranean species that thrives on rocky, salty ground. The understorey holds mastic, juniper, myrtle and heather scrub. Fauna is limited: yellow-legged gulls, the protected Audouin’s gull, and Yelkouan shearwaters nesting in the cliffs. The diomedea — the seabird the myth describes as Diomedes’ weeping companions transformed — is in fact Scopoli’s shearwater (Calonectris diomedea), which still nests here.
Sleeping and eating on San Domino
San Domino concentrates every major hotel in the archipelago: Hotel Kyrie, Hotel Gabbiano, Hotel San Domino, Hotel Eden, Villaggio Internazionale Punta del Diamante, plus around a dozen B&Bs and residences. Average rates run from €70-90 a night in a low-season B&B to €180-220 on full board in August. The complete list with phone numbers is on where to stay.
San Domino’s restaurants cluster on Piazza Belvedere and along the road down to the harbour: Gabbiano, A Furmicola, Bel Mare, Da Pio. Seafood-led cooking, average spend €30-45 a head.
San Domino as a day trip
If you only have one day, plan it like this: arrive at the harbour by 10:00, leave luggage at an agency or your hotel if you are staying overnight, take the three-hour boat tour of the five islands (€25-30 per person), lunch on Piazza Belvedere, afternoon at Cala delle Arene or on the coastal path out to Punta del Diamante for sunset, return to the harbour for the late afternoon hydrofoil (17:30-18:30). For a quick lunch, the Caffè della Marina on San Nicola and the cafés on Piazza Belvedere are the simplest options.
