Grotta del Bue Marino
Here once reigned “sea oxen”, as the locals used to call monk seals due to their tapered shape and tame behavior like that of an ox. These magnificent mammals, now (maybe) extinct, gave their name to a marvel of nature: the Sea Oxen Grottoes (Grotte del Bue Marino), since the 50’s one of the main attractions of the Gulf of Orosei, in particular in Cala Gonone, in the Dorgali territory. Today they are a favorite destination among nature lovers, and the ideal union between sea and mountain: they are part of the karstic system Codula di Luna, Italy’s most significant, seventy kilometers of tunnels in the bowels of Gennargentu. Its majestic entrance, formed by two arches over the sea, is located three kilometers away from splendid Cala Luna.
The marine caves are 15 kilometers long in total and divided into two main branches.
The northern branch, fossilized due to the interrupted karstic activity, is not accessible to the public. However, you can visit the southern branch thanks to illuminated causeways, for about 900 meters. Speleologists are allowed to explore an additional four kilometers (of the overall 5 of this branch). Seawater penetrates the vast hall, and countless little ponds of sweet water from subterraneous rivers abound, separated from sandy beaches filled with concrete formations. The “tourist” itinerary among stalactites and stalagmites offers an extraordinary color spectacle, thanks to the light beams that penetrate it. You cannot help but gasp in awe at the long shadows projected on the waters of a hidden saltwater lake, with more than one square kilometer of the surface.
The cave is also famous for esoteric rock paintings, dated back to the Neolithic, illustrating a circle of people around what is supposedly a representation of the sun. The walk finishes in the seal beach – these sea mammals once came here to mate and have their cubs. The visit is led by expert guides and lasts about one hour.
