The hike starts at the car park on Rue Louis Dumont, right next to the railway viaduct. There is a sign with a map of the various walking, cycling, mountain biking and skiing routes of the Grande Traversée du Jura (GTJ).
(S/E) Facing the sign, turn left and follow a few steps down to the banks of the Valserine, which you will follow to a metal footbridge that you will use to cross the river.
(1) Once on the other side, continue to your left until you reach a place called Métral. There is a building here with an old pump. You can cross the footbridge to see the old installations and then return to continue up the Valserine.
(2) Near the dam, there is a facility that allows fish to swim upstream (fish ladders). Continue along the path to Pont des Oules.
(3) Cross the bridge to change banks again and turn right. You will have previously ventured into the area where you can observe the erosion of the limestone rock by the water.
The path, which sometimes runs alongside the river and sometimes overlooks it, must be taken with great care, especially if the ground is wet. Continue to a tarmac road with a pumping station below.
(4) Take this uphill road to the signpost.
(5) At the sign (direction indicated: "Pont de Coz"), leave the road by turning right. You are still walking along the Valserine.
(6) At the sign (direction indicated: "Pont de Coz"), continue on your right until you reach the bridge, which you cross, then take the road on your right.
(7) At the sign, continue along the tarmac road, leaving the direction "Pont de Confort" on your right.
(8) At the sign, leave the tarmac road by turning right and continuing towards Pont des Pierres. Before you reach it, you will pass a viewpoint from which you can see the bridge and the gap beneath it.
(9) After leaving the viewpoint, join the D14A departmental road and continue to Pont des Pierres, which you will cross.
(10) At the sign, leave the road by turning right, then stay on the path along the edge of the road. Shortly afterwards, the path leaves the road and joins the 535-metre-high point, marked on the IGN 1/25000 map.
(11) At this point, turn right towards Pont de Confort.
(12) As you approach this bridge, at the signpost, follow the direction indicated for "Confort par retour du Pelant". Do not head towards the bridge.
(13) Continue straight ahead, leaving the path on your right, and follow the road to the village of Confort.
(14) You will find yourself in front of the tram, bright red and transformed into a bar to welcome you. Cross the village via the main street.
(15) Leave the main street and turn right onto the "Voie du Tram" to join theGR®9-GR®509-GTJ.
When you come to a signpost, continue straight ahead.
(16) At another sign, cross the road and continue straight ahead on the path until you reach the junction with theGR®, which you will follow by turning right.
(17) Continue on your right on theGR®, towards Pont des Oules.
(3) Just before reaching the bridge, turn left to retrace your steps along the route you took at the start of the hike, which will take you back to the starting point (S/E).
