Head up the road leading to Les Granges de la Vallée Étroite and park in the car park opposite the Paroi des Militaires.
(S/E) Cross the footbridge over the Ruisseau de la Vallée Étroite. Head left along the bank of the stream; the path is poorly marked at the start but leads easily to the Tour des Rois Mages trail.
(1) Continue along this yellow-marked path; you will easily reach the junction with the path leading to Les Granges.
(2) Continue, keeping to the left bank of the stream, cross a small tributary of the stream before reaching another junction.
(3) Here you have two options:
- turn right to take a short rocky path that’s great fun for children (option shown on the map),
- continue straight ahead to join the Lac Vert trail.
In both cases, continue to the right to reach the lake.
(4) Reach the northern end of the lake and begin a gentle climb through the woods, passing through a mountain pasture. Then continue to the right down a steep descent to reach the Pont de la Fonderie.
(5) Cross the stream via the footbridge; a few short steps uphill will take you to the wide path ofthe GR®® shared routes 5 and 57. Follow this wide path to the left to reach the Granges de la Vallée Étroite.
(6) Stay on the track until you reach the barrier at the large car park, then head left across the fields to reach the junction from the outward journey.
(2) Follow the outward route back to a footbridge, cross it and, via a path on the right bank running parallel to the road, return to the starting car park (S/E).
