Starting Point and Logistics

The tour begins in Viale Colombo 10 at Un Mare di Gadget, about 45 minutes before your scheduled departure. This ensures you’re well-organized and ready to board, with enough time to get a briefing from your guides. The boat itself isn’t described as overly crowded, so expect a comfortable group size that allows for a more intimate experience—something that often enhances the enjoyment of a scenic ride.

Visiting Grotta del Bue Marino

The highlight for many is the Grotta del Bue Marino. This karst cave system stretches over 70 km inland, with the name deriving from local shepherds’ nickname for the monk seals that used the cave to nurse their pups. Inside, the cave is divided into north and south branches, with the southern branch accessible on a well-lit, 800-meter path. The wooden footbridge and artificial lighting make it easier to navigate and truly appreciate the spectacular water reflections caused by the mixing of fresh and sea water.

Guides, like the one mentioned in some reviews, can make the experience more engaging by sharing stories about the seal nickname and the geological features. However, note that access to the caves involves an additional €10 ticket, which some travelers might find inconvenient but understand as a necessary fee for the preservation and maintenance of this natural site.

The Beach Stop at Cala Luna

Post-cave visit, the boat takes you to Cala Luna, renowned as one of Sardinia’s most iconic beaches. Its mixed sand and pebble shoreline and cliffs are perfect for taking photos or relaxing in the sun. The beach gained fame after featuring in a 1970s film, adding a touch of cinematic history to its natural charm.

You’ll have some free time to either sunbathe, swim, or explore the five caves accessible on foot along the shoreline. If you’re feeling energetic, you might opt for a trekking route from Cala Fuili, which can be reached by car. Some reviews mention taking a taxi to and from the beach, which is a nice option if you want to maximize your time.

What Travelers Say

Multiple reviews commend the stunning views and the tranquil atmosphere on the boat, describing it as “a beautiful way to see Sardinia’s coast without the hassle of land-based travel.” One traveler noted, “The caves were better than I expected, with reflections that made the inside look almost surreal.” Others appreciated the audio guides in various languages, making the experience more accessible.

A few reviews mentioned the €10 cave ticket, which is paid separately, as a minor inconvenience, but most agreed that the scenery and experience justified the additional cost. The duration of four hours was considered just right—enough to enjoy both stops without feeling rushed.
