Snorkelling at Capo Marrargiu: Discover the Wild Coast of Bosa
Dive into the unspoiled underwater world of north-western Sardinia, guided by expert naturalists along volcanic cliffs and sea caves.
This snorkelling excursion at Capo Marrargiu invites you to explore one of the most pristine and ecologically significant stretches of the Sardinian coastline. Accompanied by qualified underwater and naturalist guides, you will uncover the hidden depths and dramatic landscapes of a protected natural jewel. The experience is rated easy, making it accessible to a wide range of participants.
Departing on board a comfortable 8-metre dinghy, the route follows the rugged cliffs and secluded inlets of the north-western coast near Bosa. The volcanic geology of the area creates dramatic underwater formations and sheltered coves that harbour exceptional marine biodiversity. Your guide will interpret the natural environment throughout the journey, offering context that transforms observation into genuine understanding.
The excursion adapts its route to prevailing weather and sea conditions, visiting either the north or south coast to ensure the best possible experience. Multiple stops are planned at sites of particular ecological and geological interest, including sea caves with remarkable stalactite formations. This flexible approach ensures safety while maximising the quality of each visit.
Above the waterline, the cliffs of Capo Marrargiu host Italy's only nesting colony of the griffon vulture, a bird with a wingspan of approximately three metres and the second largest bird of prey in the world after the American Condor. Dedicated stops are made to observe these extraordinary birds, with detailed commentary from your guide. The combination of marine and terrestrial wildlife makes this excursion genuinely exceptional.

The excursion begins at the meeting point in Bosa, where guides brief participants on safety, equipment, and the planned route. You board the 8-metre dinghy and set off along the north-western Sardinian coastline toward Capo Marrargiu.
The first stop takes you to the inlets and cliffs surrounding Pagliosa Island. Here you enter the water for the first snorkelling session, exploring the rocky seabed and observing the rich marine life sheltered by the volcanic formations.
The dinghy continues along the dramatic volcanic cliffs of Capo Marrargiu, where the guide directs attention to the griffon vulture nesting sites. Dedicated time is spent observing these birds and learning about their ecology and conservation status.
The route passes through the grandiose sea caves of the Capo Marrargiu promontory, including the Grotta dei Pellicani. Inside, visible stalactite formations and the interplay of light and water create a memorable natural spectacle.
