To reach Punta Pilocca drive to the Tempio di Antas and carry on along the dirt road. After 4,5 km turn left and drive 2,5 km more then park after a small picnic area with a fountain. From the road or is impossible to see the crag as it's sheltered by the thick vegetation, anyhow is 7,0 km from the Tempio di Antas.
Google Maps may show 2 shorter roads, one from Domusnovas and the other from San Benedetto. Don't! They are in terrible shape and would get you in trouble.
Zona ZTL / Muro dei Folletti: The sector is located just below the large cliff of Punta Pilocca. Continuing along the path it is possible to reach the Muro dei Folletti
Amante Stregata: follow the road uphill, turning left before a group of houses. After 50 meters a road turns sharp to the left, going west, in the direction of the crags. Park your car at the very first bend to the right, and find a path on the left of the road.
