The Sentiero del Lupo is an educational loop trail, dedicated to the big predator, the Wolf.  From the parking lot in Vallico di Sotto follow the wide mule track which in about 20 minutes connects to Vallico di Sopra, an ancient medieval village characterized by slate roofs. The path crosses the village from bottom to top and continues following the old mule track indicated with white-red CAI trail no. 111 towards San Luigi, a magnificent mountain pasture still inhabited today by shepherds who continue the preparation of excellent cheese with their flocks. In San Luigi, take the CAI path no. 136 towards Foce Palodina.

From here, with a detour of a few minutes, it is possible to reach the summit of Monte Palodina, where the view sweeps from the Apuan Alps across the entire Garfagnana valley to the green Apennine peaks. The path continues on the slopes of Montaprato among beech, birch and chestnut woods. Turn left, at the intersection with CAI path no. 135 which in a few minutes leads to Foce Pompanella, a place of passage of the wolf, so keep your eyes open! From here, keep to the left, descending along the road, first dirt then paved, through ancient chestnut groves and small hamlets to rejoin the main asphalted road a few hundred meters above the starting point of Vallico di Sotto.
