Bue Marino Cave is a sea cave where the karst system covers over 80 kilometers inland.
Its name derives from the appellative by which the shepherds called the monk seal "Su Oe e Mare", using the ravines of the cave for the weaning of its pups.

The cave is divided into three distinct branches. To the north and the south they can be visited on foot with a distance of half a mile, while the central arm is suitable for those who practice underwater speleology.
The early visits to the cave date back to the 50s by shepherds and fishermen who accompanied researchers or curious people in the north branch which can be accessed on foot after a walk of one hour starting from the Cala Fuili - Cala Luna path.
At that time and until the 80s, the Gulf was crowded with the most numerous seal colony in Italy and the cave has become very popular soon.
Also interesting from a historical point of view because of the presence of some petroglyphs dating back to pre-Nuragic period and traced back to the Culture of Ozieri representing the "Dance of the Sun" and the cult of fertility. The presence of fresh water inside the cave, leads to the assumption that it was a sacred place for the ancient inhabitants of these lands.
The presence of soft water and the meeting point with the sea one is clearly remarkable inside the cave. The different springs and water tables create spectacular reflexes even in the sea near the inlets of Bue Marino.

Guided tours of
Bue Marino Cave

The cave is open from April to November thanks to the pick-up service guaranteed by the guides who will accompany you through the ravines of the south branch of the cave. The path is artificially illuminated and extends along a large wooden walkway.
During the visit you will admire 4 spectacular environments: the room of candelabras, adorned with limestone formations reminiscent of chandeliers; the hall of mirrors, consisting of a large room decorated with the sparkling colours of the lakes, which reflect the rich embroidered alabaster walls creating a really impressive and fascinating effect; the room of the organs, characterized by spectacular rock castings looking like actual organ pipes. The last room is one of the beaches, a wide setting where a river of fresh water flows transporting and depositing sand during the flooding.
