The Isole Tremiti Archipelago lies about 12 miles north of the Gargano promontory. It is made up of three big islands: S. Domino, S. Nicola and Caprara, of a small island called Cretaccio and a smaller island called Pianosa, situated about 12 miles northeast far from the first three islands and more than 30 miles far from Gargano's coast.
The archipelago is an example of rare beauty, both for the wild nature of its depths, for the landscape and for the historical-architectural elements of its biggest islands: S. Domino and S. Nicola.
The Isole Tremiti Marine Protected Area was established in 1989 with Decree of the 14th July 1989 in order to safeguard this incomparable heritage. The management of the Marine Nature Reserve has been entrusted since 1995 to the Gargano National Park Authority.
