■ Type of route: mid-mountain loop hike, ridge route
■ Distance: 14.5 km
■ Cumulative elevation gain: +875 m
■ Cumulative negative altitude gain: -875 m
■ Estimated total time:
■ Min and max altitude: m / 2016 m
■ Marking: the ascent to the cliffs, the sentier de ronde (GR de Pays) and the crest (PR) are marked. The route to the base of the cliffs is off-piste and requires you to make the best possible progress, avoiding obstacles (boulders, Natura 2000 protected areas). The descent of the crests via the cascade to the junction with the sentier de ronde is the trickiest, because although marked with a double yellow line, the trail is overgrown and the markings are not clearly visible.
■ Equipment in place: 2 equipped passages: at the Pas du Loup with 2 roped sections and on the descent from the waterfall with 3 sections of knotted ropes.
■ Equipment required: helmet for passages under cliffs, GPS track recommended.
Difficulties: the Pas du Loup is equipped with a rope on 2 short aerial sections, one of which includes a few steps of III climbing. The descent of the ridges to pass under the waterfall at the end of the route is tricky, steep and unstable in places, equipped with a few knotted ropes.
Access to the place
Map & topo
Hiking to the start 45 à 1h
From the road or campsite, follow the path straight up to the cliffs. You cross a track and continue for 2 long hairpin bends through the forest, coming out just below the base of the first walls, on the round path. On the left is the return via the waterfall, on the right the start of the loop.
Course 3h30 à 4h30
Part 1: the base of the cliffs to the east (1h to 1h30)
Follow the path gradually upwards towards the base of the cliffs, and fairly soon you'll find a small, steep path leading up to a part of the cliff that's bulging with long streaks of orange and black: this is the Biographie sector. Climb up to reach the flats at the base of the route starts. You can see the incredible overhang. The view over the valley is superb.
From here, the idea is to walk along the base of the walls, heading east and up all the climbing areas and beyond. You'll find a path for a good while, then, as you pass the last equipped areas, continue on, trying to keep as close to the rock as possible. The route gradually turns northwards, following the arc of the Céüse massif. We pass under the Pic de Céuse. There are a few easy climbs over boulders, 1 large finger leaning against the wall, which you can sneak under, and 2 enclosures, also to be avoided, which protect the Benoîte à fruits divers, Céüse's unique plant (Natura 2000).
Finally, after a long progression further and further north, the Dévoluy massif comes into view and, at the level of a last large boulder leaning against the wall, we are obliged to descend a little to return to the path below. Follow it, this time descending along the gradually diminishing wall. This is where the sign for the start of the ascent to the Pas du Loup crosses.
Part 2: Pas du Loup and ridge to Pic de Céüse (30' to 45')
At this point, retrace your steps almost back to the south, following a steeper path that climbs diagonally. Immediately afterwards, there's a first cabled section on a mini rock lip, a very aerial passage, more impressive than difficult. This is followed by a very narrow switchback to take a second small ledge that heads back north to the second equipped passage. This time, you have to climb (III) over a spur and then exit fairly quickly onto the wide ridge.
All that's left is to head due south on the yellow-marked path to the summit of Céüse at 2016m, where one of the ski resort's chairlifts arrives.
3rd part: the ridges to the west and return under the cliffs via the waterfall (1h30 to 2h)
The next part consists of following the edge of the cliffs to enjoy the aerial atmosphere and admire the spectacular rock formations. In some places near the summit, you can walk on suspended intermediate ledges (photo on top). Continue south-west to pass a second summit, then traverse more ridges following the relief formed by the walls. The ridge then descends, this time over slabs, before reaching a grassy flat where the via ferrata ends.
From here, follow the yellow-marked path as it descends slightly through a grassy inner valley, to emerge further on and join the ridge and cliff edge again, this time on the south-west side. Follow the ridge path for a while, veering increasingly to the west and then north-west, crossing the torrent la Lumineuse (dry in summer) until you reach the descent. The path then heads south, past a large boulder, and the waterfalls begin.
Follow the double yellow line markings. The path, which is rather overgrown and not very visible in places, weaves its way between the rocks, with a few easy climbs, and then passes under the Lumineuse torrent, which forms a pretty waterfall at this point, unfortunately dry at this time of year. A little further on, the "sentier des rondes" joins the path, which we take to the left to return slightly uphill to the junction at the start of the climb.
Exactly the same as the outward journey in the opposite direction.
