The Itinerary Breakdown

First stop: Grotta del Bue Marino
This legendary cave is part of a vast karst system that extends over 70 km inland. Its name, meaning “Sea Ox,” comes from shepherds calling monk seals, which often used the cave for pups. The cave is divided into two main branches—north and south—and you’ll visit the southern branch with a guide.

The guided walk covers around 800 meters, crossing through a well-lit pathway with a wooden footbridge. Inside, you’ll see the fascinating mix where fresh water meets sea water—spectacularly reflected near the entrances. The guide’s commentary, available in several languages, makes the experience educational and engaging.

The Cave Experience and Extra Costs

While the boat ticket covers the boat ride to the cave, you’ll need to purchase an additional €12 ticket if you wish to enter the actual Grotta del Bue Marino. This is a common point in reviews, with some travelers surprised by the extra fee, but many found the cave visit worthwhile, especially given the guide’s insights.

At Cala Luna

Once on the beach, you can sunbathe, swim, or explore the nearby caves accessible by foot—up to five in total. If you’re feeling active, the trail from Cala Fuili to Cala Luna is an option; many travelers opt for a taxi to get there, then walk back to the boat for pickup.

The reviews mention that the beach can get crowded, especially during peak months, which can detract from the peaceful vibe some might be seeking. Still, the views and the chance to jump into the clear water make it a highlight.

Timing and Flexibility

You can choose your return time from Cala Luna, with options in the late morning through the late afternoon. The later you leave, the less time you’ll have on the beach, so plan accordingly if you want maximum sunbathing or swimming.

  • What to bring: sunglasses, sun hat, swimwear, towel, and a light jacket for the boat ride.
