Park in the car park at the Ruchère ski lodge.
(S/E) Head due south and follow the snowshoe trail. This wide path forms part of theGRP® Tour de Chartreuse, whose red and yellow markings are visible on the trees. You’ll reach a junction facing a cliff.
(1) Turn left, pass through Tracol, stay on the track and reach the Col de la Ruchère. Once you reach the pass, do not venture towards the Petit Som as there is a fairly high risk of avalanches...
(2) Follow the snowshoe tracks to the right heading south-west, leaving theGRP® markings here. At the end of the descent, reach the Habert du Billon.
(3) Resume the ascent to the right; at the start of the Col d'Arpison, leave the tracks to climb due north across a meadow. This will take you to the Col d'Arpison.
(4) Head west to reach Habert d'Arpison. Turn left into the clearing, follow the edge of the woods to reach the Belvédère d'Arpison.
(5) Then turn 180° to the right, follow the edge of the woods to reach the Ruisseau de Courbière.
(6) Cross it, taking two bends – first to the right then to the left – to approach the Rochers de Pertuis. Reach the junction with the path coming from the Riondette car park.
(7) Turn left here to quickly reach the Belvédère de Pertuis.
(8) Head northwards and, at the start of the Rochers du Quartier, you’ll reach another viewpoint.
(9) Head slightly north-east and walk along the Rochers du Quartier. Then move away from them to reach the area near the car park of the Ruchère ski centre.
(10) Here you have two options:
- turn right to reach the car park (S/E).
- turn left onto the slightly uphill track leading to the Rochers du Frou, then the Pointe du Frou.
(11) Turn back and continue left to return to the car park at the Ruchère ski lodge (S/E).
