Head to the village of Cléry, above Frontenex; pass through the hamlet of Vers le Stream and take the road on the right towards Le Raffort. Park in the car park alongside the track (signposted ‘Réserve Naturelle des Bauges’).
(S/E) Take the track southwards for about a hundred metres to reach the start of the track on the right (signposted ‘Col de la Fougère’). Follow this track for 150 m to reach the bend.
(1) Follow the path, which climbs quite steeply atfirst but levels out afterwards. Ignore the path branching off to the right; follow the winding path and, after a long climb, you’ll reach the Chalets Forestiers de la Balme.
(2) At the Chalet de la Balme, take some time to rest and recover, then continue northwards, still following the switchbacks, to reach the Col de la Fougère.
(3) Ignore the path on the left and head towards the Chalet du Haut du Four and the Chalet d’Orisan.
Follow a descending path, passing beneath the Grand Roc, to reach a crossroads at La Monêt du Haut (signpost).
(4) Continue to the right, keeping in the direction of the Chalet du Haut du Four, until you reach a track that is currently under construction.
(5) Follow the track for about 400 m, then continue along the path on the right-hand side (the start is not very clearly marked due to the new track) and reach the Col du Haut du Four, passing below the chalets of the same name.
(6) From the pass, turn right onto the footpath towards the Grand Roc and reach the La Charmette junction.
(7) Stay on the ascending path, pass Mont D’Orisan and arrive at a three-way junction.
(8) Continue straight on to reach the summit of the Grand Roc via a flat path.
(9) Retrace your steps to reach the previous fork.
(8) Follow the clearly visible descending path to the right, pass by some ruins, take a hairpin bend to reach the Chalet D’Orisan – clearly visible from above – and head to the cross to enjoy the view.
(10) Head back to rejoin the path leading down to the left and, after a long descent, cross the track to meet up with it again further down.
(11) Continue along the track which leads directly back to the car park (S/E).
