At the Col de Porte, park at the top of the resort.
(S/E) Take the road towards the Charmant Som chalets.
(1) After passing the buildings, leave the road and take the track on the left.
The yellow and redGRP® Chartreuse trail markers are clearly visible. Continue to the Y-junction.
(2) Take the left fork and follow the path to the intersection (signposted Plenom), ignoring the paths on either side.
(3) Turn left towards La Pinéa (yellow markings). Go to the top of La Pinéa and back; the final section is steep but not particularly difficult.
(4) Return to the previous junction.
(3) Rejoin theGRP® and follow the ridge path straight ahead.
(5) Pass near the arrival point of a chairlift and continue along the path. The view is slightly off the path. Continue until you reach the road.
(6) Follow it to the left towards the Oratoire d'Orgeval, which is already clearly visible.
(7) Continue along the road to the Chalets du Charmant Som.
(8) Return via the road you took on the way there, with the option of cutting out some of the hairpin bends. The shortcuts are clearly marked but not signposted.
(6) Return to the crossroads you passed on the way out and continue along the road to reach the crossroads you came from.
(1) Turn left to return to the car park (S/E).
Very beautiful hike with well-maintained and well-marked trails climbing up to La Pinéa, with one fairly tricky section. The only downside is the return trip along the road, even if you cut a few hairpin bends. Otherwise, no complaints
