From Les Plans-sur-Bex, follow the road past the chapel to Mamont, then take the signed path toward Pont de Nant, climbing beside the stream, through a short rock tunnel, and crossing the water twice before reaching the car park at Pont de Nant. From there head east on the Le Richard trail, bear left at the junction near P.1372, and zigzag up through the forest. Beyond the fourth switchback, follow the path left toward the Le Lavanchy chalet, passing a large tree atop a boulder, then branch right through the trees to reach the base of the wall and the via ferrata start around 1490 m.
