The underground world of the Grotta del Bue Marino

At Cala Gonone, in Sardinia, there are many underground caves that enchant tourists and visitors almost like the beaches. These are cavities that reach the center of the mountains emerging from the sea, cyclopean caves and made up of ancient rocks. No passages have yet been found that allow you to go from one cave to another in an uninterrupted way, but if there were, it would be 70 kilometers of underground caves that would make this speleological development the longest cave in Italy. The Grotta del Bue Marino, so called because it was populated by monk seals, was opened to the public between the 1960s and 1970s. The entrance area is called the Sala della Dama Bionda because the remains of a young woman were found here. The tourist route occupies the southern part, while the north one is closed by a grate and is not open to the public. Once upon a time even goat herders would go as far as the cave to try to catch the seals, using a limestone spur.
