The caves of the Bue Marino are named after the monk seals that lived here until the 1980’s, that are called “sea cows” by the Sardinians.
The cave is five km long and is divided into two branches: the southern branch, equipped to be visited, is formed by a large gallery, where the sea flows inside to form several pools of clear water in which emerges an astonishing salt lake, about one km wide, among the largest in the world. Throughout the route you can admire the stalactites and stalagmites of different shades that create a unique play of lights with the reflections of the water. At the entrance to the southern branch you can admire the petroglyphs, graffiti dating from the Neolithic period, a series of male human figures represented dancing around bas-reliefs representing the sun. The northern branch has become fossilized because of the cessation of karstic activities.
The tour lasts about 30 minutes and it ends near the south branch, at Seal Beach, where monk seals used to gave birth to their young. The northern branch can be reached by land from the path that connects it with the beach of Cala Fuili. It takes about 40 minutes to arrive.
