The Via Cava di San Rocco is one of the most impressive Etruscan paths in the area. The trail is entirely dug into the tuff, with vertical walls reaching up to 20 meters high, hosting lush vegetation of ferns and mosses. The route connects the Lente river valley with the plateau above. Along the ascent, you will encounter ancient water channeling systems and stairs carved into the rock. Once you reach the upper end, you arrive at the panoramic area of San Rocco, from which you can enjoy the most iconic view of the settlement of Sorano and the Orsini Fortress. The ground can be damp and slippery due to the cool microclimate of the walls.

The Via Cava di San Rocco goes up the opposite side of Sorano, skirting the remains of the church of San Rocco, a religious building in Romanesque style now reduced to ruins that maintain sections of the original wall structures. Behind these remains extends a vast Etruscan necropolis with tombs dug into the tuff. The Vie Cave, dug by the Etruscans about 3000 years ago in the tuff, are still shrouded in mystery regarding the technique used to sculpt the rock so precisely and vertically. This street represents the most important of the Vie Cave around Sorano, as it guided the Etruscans to their necropolis. Incredibly, for over six centuries, from the Middle Ages until 1940, it was the only road that connected the city of Sorano to Sovana. Every horse, cart and traveler had no choice but to travel this steep, damp road between its high walls.

This exciting spot is not easy to find despite the signs and it is definitely worth looking a little further. After the last small sign, a narrow, steep branch leads to a small plateau with a thick wall and two rocky bulges. If you continue, you will discover the remains of old stairs and two collapsed caves. But the stairs bend and lead to the next plateau. Here you can discover some holes in the ground that belong to chimneys and cave openings below us. If you go slightly down to the right you will reach the cave with a fireplace that is open to the slope. If you continue straight ahead and take a little scramble down to the left, you will discover two more chambers.
