Taking a boat trip to the Bue Marino Caves from Cala Gonone offers an engaging blend of natural beauty, history, and gentle adventure. This experience, priced at around $40 per person, promises a scenic ride along Sardinia’s captivating east coast, culminating in a visit to one of its most intriguing caves. With a rating of 4.7 out of 5, many travelers find this excursion both rewarding and authentic—though it’s worth noting that it’s not suited for those prone to seasickness or claustrophobia.
What we love about this tour is how it combines a relaxed boat ride with the chance to explore extraordinary geological formations and hear stories about the monk seals that once called the caves home. The modern, comfortable vessels used for the trip, alongside the knowledgeable guides, make the whole experience feel both safe and engaging.
