Bue marino Caves

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.

Just recently, another cave was discovered which expands the karst system including the Bue Marino, making it the largest in Italy. The junction was detected on 3 June 2016 by three speleo-divers who traveled the entire connection, between aerial sections and immersed siphons, overcoming a high passage with an 8-meter rope jump and a short flooded section, about ten  meters long and two meters deep. After a further 60-meter walk, the speleologists reached a small, very deep lake: a submerged tunnel.

Speleologists from the Czech Republic had already gone here, starting from the south, who a few years ago had tried to break through without success; the traces of their passage served the explorers to understand that the circle was finally closed. On Saturday the speleo-divers finally re-emerged from the first siphon communicating to the external base camp the successful conjunction between Su Molente and Bue Marino, welcomed with deserved applause and shouts of joy by the over 60 speleologists who flocked to the external camp of Teletottes, in the municipality of Urzulei .
