The Sea

As far as the seabed is concerned, the position of the Archipelago within Bocche di Bonifacio leads to a high hydrodynamism which, associated with the scarce depth of the channels and the very low tidal range, favors the great clearness of the waters with color variations going from turquoise blue to emerald, blue, and dark blue.
The seabed preserves forms of granite erosion emerged during the latest glaciation 18 ka B.P. The extremely rare concurrence of such factors has led to the formation of a marine landscape which is rather unique in the world. As far as sea biocenosis is concerned, the fishing effort of the local fishermen has never represented a risk of impoverishment for the biocenosis, even if the situation has changed in the latest decades because of the considerable increase of tourist activities, the anchoring of pleasure boats, and the unrestrained sports fishing.

The Most Famous Beaches of the Mediterranean

With its 180 km of coasts, the Archipelago includes some of the most famous and charming beaches of the Mediterranean: in particular, Spiaggia Rosa (the pink beach) and Spiaggia del Cavaliere in Budelli, the beaches of Cala Coticcio and of the Relict in Caprera, Cala Corsara and Cala Granara in Spargi are worth a mention. Inlets and bays are unique landscape features: they represent several natural landing stages always offering a safe shelter to the seafarers. Inlets and bays are strictly linked to the colors of the sea for which the Archipelago is famous all over the world, in particular Porto Madonna, Cala Corsara, the Beach of Cala Lunga di Razzoli, Santa Maria, Cala Coticciu. The islands of the Archipelago are the result of geological processes that began with the Hercynian orogeny in the late Paleozoic era. A series of long moments of continuity alternating with transgressive-regressive sea level cycles during the Mesozoic and Tertiary eras, combined with tectonic uplift and subsidence phenomena involving the whole region have favored marked geomorphic processes with the formation of broad leveling surface areas both above and under the current sea level, on which inselberg and thor-shaped relief, as well as terraced surface areas remain as evidence.

La Spiaggia Rosa (The Pink Beach)

Enhanced by the extraordinary chromatic effect used by Michelangelo Antonioni in his film "Deserto Rosso", the first color film by the maestro from Ferrara (1964), today, thanks to the safeguard rules of the Park, it is entirely protected. The Pink Beach of Budelli is called in this way for the presence of a high percentage of bioclasts (mainly consisting of skeletal fragments of Bryozoans, especially Miriapora truncata, and foraminiferans, especially Miniacina miniacea, with a pink color) in the sedimentary formation of the sands. These bioclasts originate above all in the Posidonia oceanica meadow and feed the beach thanks to the coastal drift currents and the bottom currents. After over ten years from the introduction of the safeguard rules and the preservation measures not allowing anchorages in the Posidonia meadow, the most famous beach in the world has recovered its natural colors, the colors that bewitched the filmmaker and the many tourists attracted for years from this unique beach.
