(S/E) Head towards Les Rousses, opposite the school, and climb to the left towards the town hall.
Turn right onto Rue du Pont Perroud and follow it to the end to enter the forest via a path that leads to a property. Go around it to the right of the electricity pole (yellow mark), follow the wall to return to the woods. Follow the path downhill to the road. Take it to the left for a few metres to reach the crossroads of a path.
(1) Descend to the right along this unmarked path. From here, take great care as the path becomes very unpredictable, with many fallen trees blocking the way and making it difficult to follow. Head slightly to the left to find a path a little further down that leads to the track (yellow markings). Descend to the right to reach Pond Perroud.
(2) Cross the bridge and head left towards Les Rousses (yellow markings). Follow the path uphill to a place called Le Bonzon.
(3) Turn left onto theGR® (red and white markings), still heading towards Les Rousses. You will reach the road at the hamlet of Sagy Haut.
(4) Cross the road following the GR®. Continue to Les Rousses, Rue de la Porte de France.
(5) Turn right onto this street and immediately take the small path on the left that runs along the ramparts of the fort. You will arrive at the start of the Commandos Games.
(6) Continue right on the ramparts to reach the entrance to Fort des Rousses at Porte de Suisse. Stay on the path in the moat. At the next crossroads, climb back up the ramparts via a stone staircase. Be careful here: some steps are missing. Continue to the signpost and follow the yellow markings down into the woods. You will reach another crossroads.
(7) Continue straight ahead, taking the path marked with a yellow cross. The path on the right goes around the fort. Follow the path that descends into the forest, keeping to the edge of the meadow on the right. Once on the tarmac road, turn left and continue for about 100 metres until you reach the hairpin bend.
(8) Turn right onto the small path that leads to the GTJ (Grande Traversée du Jura trail). Take it to the left to reach the footbridge over the leat de la Chaille.
(9) Cross and head uphill towards Prémanon. You will arrive at the tarmac road in Prémanon d'Amont. Follow it to return to the entrance of the village via the Route des Rousses and continue to the car park where you started (S/E).
