Cala delle Arene is the main sandy beach on the island of San Domino, the largest of the Isole Tremiti archipelago in the northern Adriatic, part of the Foggia Province of Apulia. The Tremiti Islands — San Domino, San Nicola, Capraia, Cretaccio, and Pianosa — form a small remote archipelago some 25 kilometres north of the Gargano coast and approximately 45 minutes by hydrofoil from Vieste. The entire island group and its surrounding sea lies within the Tremiti Islands Marine Reserve, and the water clarity here is among the finest in the Italian Adriatic as a direct result of that protection.
Cala delle Arene sits on the southwestern face of San Domino, sheltered from the prevailing northerly breezes by the body of the island. It is one of the few sandy beaches in the Tremiti group; most of the island coastline is rocky, with dramatic sea caves and cliff inlets. The beach consists of a relatively small arc of fine pale sand — perhaps 100 metres — that shelves gently into turquoise and then deep-blue water of exceptional clarity. Posidonia seagrass meadows dominate the seabed beyond the shallow entry zone, contributing to the protected marine environment. The surrounding sea is one of the best diving destinations in the southern Adriatic, with dive sites including historical wrecks, sea caves, and vertical cliff walls.
Access to the island is by ferry or hydrofoil from Vieste (45 minutes, approximately 20 euros return), Termoli, Manfredonia, or Pescara. On San Domino, the port is a 20-minute walk from Cala delle Arene; a paid island shuttle operates in summer. Accommodation on the island is limited and fills early — multi-day visitors must book months in advance for July–August stays. Day-trip visitors are numerous in summer and the beach can become very crowded on busy days. A beach bar operates in season. Snorkelling and guided dive excursions depart from the San Domino port throughout the summer months.
