Laguna Di Cala Luna
For around 15 euros extra per person, you can combine the boat trip to Cala Luna with a visit to the Grotta del Bue Marino (the "Cave of the Sea Cow" – a reference to the monk seals that once lived here). This huge sea cave has stalactites, stalagmites, an underground beach and traces of neolithic rock carvings.
