The start is from Saint-Pierre-d'Entremont (Savoie), which can be reached from:
- Saint-Pierre-de-Chartreuse via the Col du Cucheron,
- Les Échelles via the Pas du Frou,
- Chambéry via the Col du Granier.
The return journey requires you to start from the bottom of the valley. The most convenient parking is in front of the church in Saint-Pierre-d'Entremont (Savoie).
(S/E) Cross the Cozon, opposite the car park, and turn left towards the valley. Quickly veer right to start climbing a housing estate road and turn immediately before thefirst house on the right to climb a path for about a hundred metres. Turn left to climb a circular section of the housing estate road. Above this circular, climb to the right up the historic path that winds through the hedges to reach the last circular of the Roche Veyrand housing estate.
(1) Turn right off the road onto a path that heads west at first and then gradually north into the forest.
Near some old buildings, turn left (you can also turn right, but logging has severely damaged the area). At the crossroads of paths on the climb, leave the Col de la Coche path towards Corbel and turn right to return east to a place called Sous la Roche in the clearings, where you will find the last building.
(2) Turn left to begin the steepest part of the route. The trail climbs straight up the slope, then winds its way up fairly steep slopes, sometimes close to the cliffs. Pass the access to the Via Ferrata on your left, which leads to the Himalayan footbridge further on.
After a steep and rocky detour to the right, the trail returns above the cliff at the end of the Via Ferrata.
(3) Then climb back up into the forest for the last part of the ascent, which remains steep but is no longer exposed, until you reach the summit and its cross on the edge of the cliff.
(4) Descend the eastern slope into the forest, following a path that gradually becomes a logging track and, at the end, a forest road at a clearing known as Le Grand Jet.
(5) Leave the road, which continues on level ground towards the Col du Cucheron, and take the path that descends to the right. After following the forest road for a short distance, it plunges towards the Monts where it rejoins the meadows. Continue along a small ridge and descend to the buildings of the Hameau de la Tournette.
(6) Turn sharply right to descend southwards, pass the buildings of La Tronche, and leave the descent to Les Courriers on your left. The path gradually emerges from the forest to follow a ridge where crumbly rocks (fossils) outcrop and joins the tarmac road at Le Crêt.
(7) Turn right to descend and cross the dense hamlet of La Fracette.
(8) Before leaving the hamlet, at the fountain, turn right onto the small road that leads back to the main town of Saint-Pierre-d'Entremont, along the right bank of the Cozon. (S/E).
