Description of the walk

At Pont-du-Fossé, park in the car park in the centre of the village (location of the ice rink in winter).

(S/E) Walk along the Drac (torrent) and cross the bridge that leads to Pont-du-Fossé, then turn left immediately after the bridge.

(1) After 100 metres, turn left onto a dirt road and follow the Drac as closely as possible. Continue along this road until you reach the forest, where you will have to climb a steep slope until you reach a flat path. This path runs alongside a canal.

(2) Turn right onto this path and follow it westwards through the forest.

(3) Turn left onto a path that climbs the mountain. Pass the hamlet of Le Costillon and continue until you reach Coste Belle.

(4) Cross the ruins of the old village of Coste Belle until you reach a wide path that turns into a forest road and continue climbing.

(5) Turn right onto a beautiful forest road that continues steadily uphill through the forest.

(6) You will arrive at a crossroads of forest roads, the highest point of the route. Turn right and begin the descent, still on a forest road. The village of Saint-Léger-les-Mélèzes becomes visible at certain bends. Continue until you reach a tarmac road, where you should turn right for 50 metres.

(7) Leave the road on the right and take a path. Follow the yellow markings. The forest path down the valley is very pleasant.

(8) At the intersection, head towards Bois la Barbe, staying on the path until you reach a larger path, where you should turn right. Cross a road and continue until you reach the canal path.

(9) Walk along the canal, turning right (do not take the nearby tarmac road). You will pass a very pretty waterfall.

(3) At the crossroads, turn left and descend to the village of Pont-du-Fossé. Return to the intersection you passed at the start of the route.

(1) Follow the route in reverse to return to the car park (S/E).

This route has two very different sections that, in my opinion, are suited to two different types of hikers. The first section is a steep, pretty trail that leads to meadows with ruins. This is followed by several kilometres of monotonous forest road. Fortunately, we followed a tip and took a small downhill trail, which is very pretty, but be careful as the leaves cover the ground and walking sticks are useful. Apart from the uphill trail and this unmarked downhill trail, the rest is of little interest.

moderate hike with a slightly steep climb to the ruins of Costebelle when you leave the path along the Gap Canal, then no major difficulties. Beautiful view of the Champsaur region
duration: 3½ hours in a group. Allow an extra hour

A lovely, enjoyable walk on 15 August 2023, lasting just over three hours, covering 11 km and 720 metres of elevation gain there was a slight climb to reach the village, but nothing too difficult, with some lovely views along the way. We picked lots of raspberries and passed a car at the highest point, a fire engine on call, and three hikers, two trail runners and a berry picker on our way, so not many people.
Almost entirely in the shade, very pleasant, good for getting in shape.

Thanks to the author for mapping out this hike.
We do not share the enthusiasm of previous hikers.
The climb to Coste Belle is indeed quite steep in places (however, it is not difficult – we completed the hike with a 5-month-old baby).
The scenery up to Coste Belle is beautiful.
Once past the village, the climb becomes very gentle.
The forest track is of no interest.
From point 6 onwards, the forest track turns into a motorway! We passed at least fifteen cars. This is not at all what we were looking for.
My watch shows a distance of 11 kilometres and 623 metres of elevation gain. My companion's watch shows the same. Yet our GPS tracks are identical to those of the author.
Much of the hike is under the trees, which is perfect when the sun is beating down or when it's raining.
Unfortunately, we couldn't enjoy the raspberries due to the drought.
In short, it was nice at the beginning, but a little less so after Coste Belle.

A very pleasant walk in the shade in the morning, which is important given the current heatwave
The climb is steep, so take your time and go at your own pace.
Very pretty views of Champsaur.
Worth doing again and again

A beautiful walk in the mid-mountains, pleasant on a sunny day as it is mostly in the shade. The landscapes are varied, the ruined hamlet is charming, and there are raspberries and wild strawberries along the way...!
We highly recommend it.

A lovely hike without any major difficulties. The climbs are steep, but with breaks to enjoy the panoramic views, they are fairly easy to manage.

The descent is pleasant, passing close to some very pretty chalets.

Very few people encountered on this route!

a fairly easy walk with a stop at a promontory where you can admire the view of the village of LA BREOLE and the Durance valley on the ESPINASSES side. The trail then takes you to the Serre Poncon dam at a place called Coste Belle, where the view is breathtaking if you are lucky enough to have blue skies and no wind. The return journey is partly through woodland and then leads onto a tarmac road back to the village. A pleasant hike for the whole family, even with children.
