Situation

The route involves 480 m on foot, 25 min. Once you reach the settlement of Opedaletto along the SS317 that leads to Monte Peglia, take the SP109 that leads to Ripalvella and Collelungo, proceed for about 6.7 km along the dirt road and park in the clearing on the hairpin bend near a gate at the locality Sorbare di Sopra. Proceed on foot through the open field on the South side of the road, making your way among the shrubs without a clear track. After about 200 m you enter the bosco (woods) to the right of the field and ford the stream, following it downhill always on the right side. After about 170 m the bosco (woods) thins out and you walk on bare rock with a slight slope in a Southerly direction; after about 100 m you reach the cave in the scrub, near the orographic right of the stream.

Route information: there is no beaten path; scrub or bosco (woodland); dangerous access.

Entrance: a wide floor entrance of about 2x2 m protected by a grate, located slightly above the orographic right of the Fosso del Pozzo, also protected by a fence with barbed wire. Entrance setting: natural. Access: fence, door/grate; closed cave; protective grate and barbed wire. Locality: Ospedaletto, Podere il Pozzo.
