The Bue Marino Caves are one of the most extraordinary natural attractions on the east coast of Sardinia. Located just south of Cala Gonone, this vast cave system was once the last refuge of the Mediterranean monk seal — the bue marino (sea ox) from which the caves take their name.
Bue Marino Caves: Cala Gonone’s Hidden Treasure
The caves extend for several kilometres into the limestone cliff. Visitors walk along well-lit pathways past spectacular stalactites and stalagmites, underground lakes of still, clear water, and Neolithic rock engravings depicting a ritual dance — among the most important prehistoric finds in Sardinia.
The play of light on the water inside the caves creates an atmosphere that is both serene and awe-inspiring. The temperature inside is a pleasant 15-18°C year-round, a welcome break from the summer heat.
Guided Cave Tours
The caves can only be visited on a guided tour (not run by Daymar), which lasts approximately one hour. Tours run several times a day during the summer season. The cave tour cost is not included in the guided excursion price. Tickets are purchased before departure, at the harbour, from the Bue Marino Caves ticket office.
How to Visit
The caves are just 10 minutes by boat from Cala Gonone harbour — the closest major attraction.
- Guided excursion with Daymar — Our guided boat excursions include the Bue Marino Caves as the first stop of the day. Your skipper knows the optimal times to arrive and avoid queues.
- Exclusive boat with skipper — With our exclusive skipper rental, you can organise a personalised day that includes the caves and the gulf beaches at your own pace.
The caves are the ideal first stop of the day: visit in the morning and then continue south along the coast to the beaches of the Gulf of Orosei.
