You’ll meet at the port of Cala Gonone, picking up your boarding pass at least 30 minutes before the scheduled departure. The tour is operated by Nuovo Consorzio Trasporti Marittimi, which is known for its reliable, well-organized maritime trips. The meeting point at the ticket office is straightforward, and you’ll be given an audio guide in several languages, including English, Italian, French, and German—handy for those who want to absorb a bit of local color or scientific background during the trip.
The tour lasts about 5 hours, which balances enough time for each stop without feeling rushed. Departures are seasonal, running from about 12:30 to 18:30, with the exact schedule depending on the time of year. It’s worth noting that passenger safety is prioritized, and the captain may change routes or stopovers if conditions warrant it—something to keep in mind if you’re a meticulous planner.
The highlight for many is the visit to the Grotta del Bue Marino (Sea Ox Cave), a site that has fascinated visitors since the 1950s. The name refers to the monk seals once common in the area, affectionately called “sea ox” due to their shape and gentle nature. The excursion inside takes roughly an hour, during which expert guides share insights into the cave’s history, geology, and its unique fauna.
You get access to the southern branch of the cave, which is accessible via an easy walkway. The interior is a marvel—stalactites and stalagmites adorn the rock walls, and the atmosphere is cool and slightly humid, offering a refreshing break from the Sardinian sun. Guides like the ones praised in reviews (though not always name-dropped) are knowledgeable and engaging, making the scientific commentary accessible and interesting.
The entrance fee for the cave isn’t included in the tour price, so be prepared to pay a small additional fee (not specified exactly here but something to budget for). The cave’s interior really showcases nature’s artistry—a must-see for anyone interested in geology or natural history.
After the cave visit, the boat continues through the Gulf of Orosei, revealing spectacular coastal vistas. Expect to see dramatic cliffs, sea caves, and pristine waters. Swim stops are part of the itinerary, giving you the chance to dip into the clear, inviting waters—perfect for cooling off after the cave exploration.
The boat’s size and speed are designed for comfort and scenic viewing, with plenty of space to relax or take photos. The audioguide enhances the experience, providing context about the coastline, local wildlife, and the geological features. According to reviews, the crew is friendly and attentive, often giving tips about the best spots to swim or snap photos.

The 800-meter-long crescent of white sand is framed by six large caves and backed by a lush oleander forest, offering a picture-perfect scene. The beach is protected from the treacherous sirocco winds by a rock wall, allowing calmer waters perfect for swimming.
Walking through the oleander forest, you can access the “codula,” a trail that takes you into the surrounding dense Mediterranean scrub—an exciting hike that might reveal rare birds of prey, wild boar, and goats. Some travelers, like one reviewer, mentioned that the crowds can be overwhelming at Cala Luna, especially when multiple boats arrive during the peak season. However, the expansive sands typically offer enough space for everyone to find a spot.
In the afternoon, boat departures from Cala Luna to Cala Gonone are hourly, depending on the season. Many travelers appreciate the flexibility, allowing you to linger at the beach or explore the surroundings at your own pace before heading back.
At $47 per person, this tour offers good value considering the boat trips, the guided cave visit, and the scenic nature of the experience. The cave visit alone would be worth a small extra fee, and the opportunity to relax at Cala Luna adds significant appeal. Keep in mind, food and drinks aren’t included, but there are plenty of nearby spots to grab a snack or drink after the tour.

This tour is best suited for travelers who enjoy a mix of cultural, natural, and leisurely experiences. Families, couples, or groups wanting an accessible way to see Sardinia’s coastal highlights will find it particularly appealing. The knowledgeable guides and the stunning scenery consistently receive praise, making the experience feel both educational and visually rewarding.
However, those seeking peace and solitude might want to visit Cala Luna early in the morning or later in the season, as it can become quite crowded. The cave visit, with its fascinating formations and wildlife, is genuinely a highlight and a chance to step into a natural world few get to see.
This tour combines value, scenic beauty, and cultural depth in a way that captures the essence of Sardinia’s coast. It’s a memorable outing for anyone wanting a compact yet enriching experience of the Gulf of Orosei.
