This trail is a branch of the E 201 one. It has a length of about 500 meters and leads to the romanesque basilica of San Pietro di Sorres. Halfway along the trail there is an access to the SIC (sites of Community importance) area of Sa Grotta Ulari, an important bat nursery that can be visited accompanied by guides.
The trail ends at the entrance to the churchyard of the basilica home to the Benedictine monastery where is possible to carry out numerous activities and find hospitality.
