They are a protected marine area and part of the Gargano National Park.
The archipelago consists of five islands: San Nicola, administrative and historical center, San Domino, the largest and most green, the rugged Capraia, the rock Cretaccio and Pianosa, the most distant and difficult to reach, integral marine reserve. Only the first two are inhabited, connected to the Adriatic coast by ferries and hydrofoils departing from Capojale, Rodi Garganico, Peschici, Vieste, but also from Termoli in Molise, from Vasto and Ortona in Abruzzo. A shuttle service and numerous organized excursions allow you to reach the other islands of the archipelago. Cars are not allowed on the Tremiti.
A true paradise for lovers of the sea and diving, the islands contain bays and diving sites of remarkable beauty and importance, both for the presence of rare species and for the many ancient wrecks that make it almost an underwater archaeological museum.
On San Nicola isle there is the “Santa Maria al Mare Abbey”, guardian of a mosaic and a crucifix of considerable artistic importance.
