Grotta di Pizzo Corvo

Coming from Narni, follow Strada delle Pretare SP64 until you pass Lago di Recentino. Then turn right onto Strada di Colombata up to the house at the edge of the bosco, at the height of which the dirt road turns sharply right. After about 50 m there is space to leave the car. From here go back in the direction of the house. On the left you see a metal bar that can be crossed on foot to take the path that runs alongside the bosco (Strada di Colle Rosso path); follow it keeping the house on the left and the bosco on the right. On reaching a junction, turn right and then, after a few metres, immediately left along an evident track that leaves the methane pipeline route on the right, entering the bosco uphill. Follow the path for about 100 m to the disused fence with an old danger sign that runs along the overhanging rim of the doline. Route: 300 m, 10 min. on foot. Route information: Scrub or bushes, Walkable path.

Entrance: wide overhanging doline opening on the wooded slope. Entrance setting: Natural, Slope. Access: open, fence with barbed wire, damaged; beyond the fence the wall is immediately overhanging. Location: Casa Colombaia, near Villa Eroli.
