Bue Marino's karst complex

Bue Marino Cave is located in the centre of the Gulf of Orosei and it has been visited for over fifty years by thousands of tourists from all over the world. Bue Marino is the Sardinian translation for Monk Seal, which found one of its important refuges in this cave until the mid-seventies. It is composed of three branches: the Central Branch, the Northern Branch, and the Southern Branch, but only the last two are accessible. The Northern Branch consists of large fossil galleries on whose walls are present signs of a higher sea level and from which it is possible to observe three lakes: Emerald Lake, Abyssal Lake, and Black Lake. The Southern Branch is characterized by magnificent galleries of white sand, interspersed with fresh water lakes, while along the tourist path we find the Chandelier Room, the Mirror Room, the Organ Pipes Room, and the Seal Beach.

Southern branch

The tourist branch is accessible by sea with boats departing daily from the port of Cala Gonone, where there is a ticket office for purchasing entrance tickets.

central branch

Central branch is actually a section that can only be visited by professionals with speleo diving equipment, and it is not accessible to the general public.

northern branch

Today the Northern Branch is reserved for speleological expeditions, but it is also possible to access it on foot by the trail that starts from Cala Fuili beach.
