Park in the stream Fourchu car park.
(S/E) Walk back up the track for a few dozen metres, then cross the Chéran via a footbridge.
(1) Climb up into the forest via a winding, sometimes steep path, ford the Osier stream several times and you will arrive at a more open space at Combe Fort.
(2) Continue north along a balcony path that rejoins the forest before reaching an intersection.
(3) Turn almost 180° and take a narrow path for a steady climb up a ridge. This will take you to Pointe de la Fougère.
(4) Descend via the steep path that heads north along another ridge and leads to a junction.
(5) Here you have two options:
- if you go left, you can make a quick descent through the forest to return to the starting point,
- for a longer hike, continue for 300 metres to reach the Col de la Fougère (1,680 metres).
(6) At the pass, leave the path on the right leading down to the Isère valley and continue north on a balcony path beneath the cliffs of Grand Roc and Mont d'Orisan. This will take you to the junction with theGRP® of the Massif des Bauges (yellow and red markings).
(7) Before taking theGRP® downhill to the left, you can make a short detour to the Fontaine de la Croix de Fer.
Then descend for a long time through the forest. The trail will soon follow the Chéran valley to reach an intersection with the trail that descends directly from Pointe de la Fougère. Continue descending, cross the Chéran and join a wide track.
(8) Descend to the left to return to the first crossroads.
(1) Follow the same route as on the way up to return to the car park (S/E).
