Starting from the village of San Piero, a small hamlet located in a panoramic position behind Marina di Campo, a trail to discover the millennial use of granite rock on the southern slope of Mt. Capanne. From the modern quarries, where some stonemasons still remain who work the granite as their grandparents did, the route winds through the essences of the Mediterranean scrub, such as Cisto Marino, Ginestra , Lavender, always with a privileged panoramic view of the islands on the southern side of the archipelago, Giglio, Montecristo, Pianosa, and in the distance even the mountainous reliefs of Corsica. Passing by the mill of Moncione, evidence of the rural past of the area, where cereals and chestnuts were ground, and then by the "ancient quarries," a place of workmanship from the Roman era, where we can still see the various stages of workmanship of the columns that departed from here to adorn the monuments of ancient Rome, we will descend to the beach of Cavoli, with its crystal-clear water, an ideal place for a break before embarking on the last stretch towards the return to San Piero, all always surrounded by a spectacular panorama of the islands of the archipelago.
