From the village of San Peretto, continue uphill on the left as far as the Crosetta-Calcarole junction.

Keeping to the left, you come to the hamlet of Castel where there is an attractive wash-house.

From Castel, proceed to Ara, then Preperchiusa. Follow the path on the left to the hamlets of Siresol and, further down, Concole. Near Trentin, leave the provincial road and continue downhill to Bressa. From here, keep on going down until you return to the starting point.

The walk takes about 2h and is of medium difficulty.
