The starting point is in MontBrilland (on the D436 between Saint-Claude and Septmoncel, just before a mill.
(S/E) Follow the D436 towards Septmoncel for about 700 m (be careful!)
(1) After a tunnel, take a path leading down to the right towards the valley floor and the River Flumen. Pass a track on your right and head down to the river.
(2) Once you reach the river, you can access the Flumen waterfalls via a short detour to the left (shown on the map). Turn back and continue straight on towards the power station overlooking the River Flumen.
(3) At the power station, take a path on the left towards La Roche Blanche. About 300 m further up, take the path on the left, which is quite steep for the most part. You’ll reach the La Roche Blanche viewpoint (1140 m), which offers a stunning view of the valley and Saint-Claude.
(4) After admiring the scenery around La Roche Blanche, continue along the path on the right; please note that the route has been altered (the yellow markings provided will help you find your way). Once you reach a tarmac road, follow it to the left for about 300 m, then turn left (following the yellow markings).
(5) Turn left, then left again just before the road (D25) onto a fairly pleasant track, which will take you to Les Moulins after a short while
(6) Follow the road (D436) to the left downhill for about 250 m. Take a path leading down to the left which rejoins the road a little further down. Turn right onto the road, heading uphill. After a hairpin bend, take a path on the right which rejoins the road a little further up.
At the road, head right for a few metres, then take a path on the left towards Septmoncel and the Chapeau de Gendarme (you can actually see the latter by taking a short detour, continuing along the road for 300 metres there and back).
(7) At thefirst junction, take the path on the left towards Sur les Grés. The fairly direct ascent takes place mainly through pastureland.
(8) At the summit (1,089 m), take in the view, then continue along the path to the right towards Septmoncel and the “Chemin des Moines”.
(9) At thefirst junction, turn left onto the Chemin des Moines (the main route between Saint-Claude and Septmoncel until 1884). It descends towards Montbrilland (no particular difficulties).
Once you reach a building, turn right and join the D436. Turn right to return to the starting point (S/E).
