    Site Overview

    The Grotta del Bue Marino in the Gulf of Orosei is a huge partially submerged karst cave with spectacular stalactites and clear water, dived on guided tours that respect the fragile environment. Red gorgonians and morays decorate the entrance, while the inner sections reveal the drama of the flooded limestone. It is a favourite for the unique geology and a gentle intermediate dive that combines cave wonder with healthy reef life just outside. The Orosei coast above is a bonus. The site rewards careful planning, good buoyancy and a respect for Italy’s marine-protection rules, and remains a favourite among Mediterranean divers.
