From Foroglio follow the signs for Roseto. After crossing the road, pass to the opposite side of the Bavona river and continue through the floodplain forest towards Faedo and then Sonlerto. From the center of the village, descend onto the road, which you walk for about a hundred meters, then take the path on the left to reach the Gannariente locality. Here is the Oratory of Santa Maria delle Grazie. Continue on the left side of the carriageway until San Carlo.
