Probably the most famous cave of Sardinia, because of the location right at a beautiful cove. High and bright white limestone cliffs above the turquoise water of the Mediterranean Sea, and a cave at the foot of the cliff. The boats from nearby Cala Gonon, the harbour of Dorgali, land right here at the cave entrance. But for less adventurous there is also a footpath through a tunnel down the cliff from the parking lot above.
This cave was named after Bue Marino, the Mediterranean monk seal or sea ox. It was famous for colony of those seals, but they have vanished now. Some say as a result of tourism, but scientific research found some circumstantial evidence, that they naturally move their location now and then. Probably they will return, especially as the area is now part Golfo di Orosei National Park.
The cave is famous for its huge passages and chambers, which are of impressive height. The first hall is lit by the reflection of the sea, and so it has an otherworldly shimmering. Other halls show prehistoric engravings, which show that this cave was used by man for ten thousand years.
The Bue Marino Cave was surveyed to be 17,400 m long But it has been connected to the Karst complex of Codula Ilune, Bue marino, Su Molente which extends over 70 km. It is currently  the longest cave of Italy.
