Not far from Cala Sisine appears Cala Biriola with its distinctive natural rock arch.

This earthly paradise is situated under a dense wood which hides the charcoal burners’ old paths and tracks. Still today, you can find the traces of that hard business. In fact, scanning the cliff with attention, you can still notice the remains of the rails which were used to transport the coal to the beach where it was loaded on sailing ships.
