Located along the majestic limestone cliffs of the Gulf of Orosei at 10 meters above the sea level, the Grotta del Fico is particularly important for the siphons that connect it to the sea and that used to offer access to the monk seal to the inland beaches and small caves where she could reproduce herself.
1 Km long, this is one of the most impressive caves in Europe; still alive (the concretions continue to form), it takes its name from the particular colors and look of its conformations.
