It tells the story of the sea and life on the archipelago over the centuries. Staged and inaugurated in 2006 in Caprera - connected by a long artificial isthmus to the ‘big sister’ La Maddalena - by the managing authority of the Archipelago National Park, in collaboration with the Italia Nostra Association, the Museum of the Sea and Maritime Traditions will accompany you in the discovery of the history and culture of La Maddalena relived through the sea routes, on a chronological journey divided into sections, from prehistory (starting from the Neolithic period) to today.

The collection is made up of artefacts donated by institutions, volunteers of the association, fishermen and other private individuals: historical images, maritime and military documents, scale models, remains of ancient and modern sailing and motor boats, navigation instruments, work tools, machinery for engines and fishing equipment. The most distinctive objects are ancient, such as the Tabula Peutinger - a map of Roman origin that portrays the entire street map of the Empire in the 3rd-4th century AD -, and the ‘Mother Goddess’ made of granite, or they refer to prehistory, such as the ‘wooden sculptures’ by Bruschi depicting Nuragic deities. Others are modern, such as a sundial engraved on copper plates, the twin-pan balance and a precision calibre gauge. The visit to the rooms is accompanied by the narration of historical events.

Caprera is the second largest island of the archipelago and the last residence of Giuseppe Garibaldi. On the subject of the Hero of The Two Worlds and places of culture, don't miss the Compendio Garibaldino,​ one of the most frequently visited museums in Italy. Then a dip in the sea is a must, observing the limits imposed by the national park. In the area under the full protection scheme, don’t miss Cala Coticcio, the ‘Sardinian Tahiti’. To the south-east, Cala Portese (or dei Due Mari) is noteworthy, where the water bathes both sides of the inlet, as is the splendid Spiaggia del Relitto (Beach of the Wreckage). To the west, worthy of a visit are the blue waters of Cala Napoletana, the wild nature of ​Cala Garibaldi and the expanse of light sand of Cala Serena.
