Exploring the Itinerary and Highlights

Visiting Grotta del Bue Marino

The Sea Ox Cave (Grotta del Bue Marino) is the centerpiece of this tour. Its name, meaning “Sea Ox,” reflects its historical connection to monk seals that used the cave for pup-rearing. This cave is part of a vast karst system extending over 70 km inland, which adds to its natural allure.

Inside, you’ll find a landscape shaped by water and time. The cave has two branches—north and south—where the meeting of freshwater and sea water creates shimmering reflections. The southern branch can be visited with experienced guides crossing about 800 meters of artificially lit pathways and wooden footbridges. Visitors have noted that the cave’s spectacular light effects and reflections are truly captivating.

According to a review, “The guide was extremely informative,” which makes the walk both educational and visually stunning. However, keep in mind that exploring the inside of the cave requires an additional €12 ticket purchased separately at the harbor, so budget planning is advisable.

The Scenic Boat Ride

The cruise from Cala Gonone to the cave and Cala Luna takes just under 30 minutes, offering a comfortable ride over calm waters. Many travelers appreciate the relaxing boat journey as a way to see more of Sardinia’s rugged coastline without the hassle of driving. You’ll be seated on deck, enjoying the breeze and panoramic views.

Discovering Cala Luna

Cala Luna is one of Sardinia’s most iconic beaches, thanks to its dramatic setting and history. It gained fame as the set for the 1970s film “Swept Away” by Lina Wertmüller, which adds to its allure. The shoreline features a blend of sand and pebbles, with five caves accessible on foot.

The beach is often busy, especially in summer, and reviewers mention its crowded nature during peak hours. One noted, “There was quite a lot going on, which takes away a bit of the charm,” indicating that if you prefer serene scenes, an early or later visit might be better.

You can reach Cala Luna from Cala Fuili on foot, or take a taxi and walk the trail back, then return by boat. This flexibility allows you to tailor your time on the beach. At the end of your day, you’ll enjoy the chance to sunbathe, swim, or explore the caves nearby.
