Le Gouffre-des-Busserailles

The route starts from the hamlet of Crépin, which can be reached by car or on foot along the "health trail" that runs alongside the Marmore stream, passing the cable car base. From here, climb a short stretch of trail and then take the slightly uphill dirt road on the right, marked no. 1, towards Cervinia. You reach the hamlet of Les Prés, and from there, a flat trail crosses green meadows until you reach the small oratory/chapel of Pont de la Sée. From here, cross the small bridge and, with a final uphill stretch, reach the ravine. For an alternative return, follow the trail on the left bank of the stream marked no. 24, passing through the hamlet of Singlin and then arriving at the cable car parking lot (La Glarénaz).
