Description of the walk

From the N85, 500 metres north of Col Bayard, a small road branches off to the left (west) (wooden sign) towards Col de Gleize, where you will find the Col de Gleize car park.

(S/E) The trail starts to the north, behind the forest house. Follow the signpost. The trail climbs very quickly in switchbacks through the forest, mainly pine and larch, to reach an alpine pasture.

(1) At the "Le Forest de l'Amouty" signpost (1,830 m), continue straight ahead, following the direction of Pic de Gleize.

(2) At around 1970m, a small, inconspicuous crossroads marked on the ground by a yellow mark on a rock gives you two choices:
- the first on the left, which is rather exposed, climbs up the ridge on the mountainside.
- The second one on the right goes through a pass.
We chose the first option (left), which is certainly more fun and joins the ridge of Pic de Gleize. You have to climb this ridge almost to the summit.
You will pass small rocky outcrops where you may need to use your hands. Then, follow the ridge to reach the summit.

(3) From there, take a moment to enjoy the view. Then head west towards Pic de Chaudin. Descend and then quickly climb back up to the summit. The peak looks impressive in the foreground, in front of Pic de Bure.

(4) From Pic de Chaudin, retrace your steps.

(5) In a hollow and before climbing back up, look for a path that follows a contour line and follow it to the pass.

(6) At the pass, continue straight ahead, keeping Pic de l'Aiguille in your sights, and walk along the ridge. Please note: as you walk, the path becomes narrower and steeper... The end is very exposed, so it is best to stop a little before you reach it.

(7) When you decide to turn back, you will need to retrace your steps to return to the pass.

(6) Back at the pass, descend to the right and continue to follow the yellow markings. The descent is quite steep but easy, with just one rocky section that is a little tricky to navigate before you come out onto a mountain pasture. From there, you will need to be careful as the path disappears a little in the grass of the mountain pasture: keep an eye out for the yellow markings, which occasionally disappear; the important thing is to stay on course: north-west. Continue the descent to the crossroads of paths in the valley near the sources of the Buech.

(8) When you reach a wide path, turn left. You will find a clearly visible path marked with yellow signs. This path remains on a ledge for a long time. Notice the ruins of the old village of Chaudun below. Continue along this ledge path. Go around the Montagne de Chaudun to reach
the Col de Chabenottes (sign).

(9) Continue straight on towards the Col du Milieu.

(10) When you reach the Chaudun forest road, continue straight ahead to return to the car park (S/E).

Worth a visit

The village of Chaudin, which can be seen on the way back, was founded by transhumant shepherds. Known since the 12th century as the fiefdom of the chapter of Gap, it was abandoned in the 19th century.
The entire area is now classified as a Natura 2000 site.

This superb hike is for experienced hikers because, as mentioned by others, access to the summit of the Aiguille peak is difficult (but you don't have to climb to the summit to enjoy the scenery). However, the descent is very difficult and, on the bright side, it will certainly be equipped with chains very soon

Very beautiful hike.
A bit crowded at Pic de Gleize, but the other two peaks and the tour of Chaudun Mountain were really peaceful.
As for Pic de l'Aiguille, we didn't quite make it to the summit as we weren't very comfortable on the ridge at the end. Otherwise, there were no difficulties.

A very pleasant and accessible route on the way up. Rich in biodiversity.
Be careful on a very tricky section of the descent near a rocky outcrop.
Caution is advised with children or people prone to vertigo on the return trail.

A very beautiful route with superb views. Only frequented up to the first peak.
However, the route is reserved for hikers who are experienced in mountain walking, particularly towards the Pic de l'Aiguille.

A magnificent hike with views (and what views!) along almost the entire route.
What's more, the paths are well marked and the gradient is steady, making it almost ideal for an old man like me.

A few comments:
- In the description, "waypoint" no. 9 * is called "Col de Chabanottes (1663 m)." In fact, the route does not pass through the Col de Chabanottes, but remains above it. At point 9, there is only a sign indicating the direction of the pass. But I think it is clear to everyone that you should not go down there and stay on the "sentier de ronde" (patrol path).
- The description mentions a "slightly tricky rocky section" on the descent between points 6 and 8. It has been equipped (recently, it seems) with two bolts/plates (to secure the passage? To install a handrail?). However, you still need to have brought a piece of rope and a few carabiners, and therefore have been informed of the existence of this equipment, in order to be able to use it. Please note for those interested.
- After point 8, the trail crosses several ravines corresponding to the headwaters of the torrent. In the last one, the path is very damaged and the passage is "tricky", even though slipping is impossible due to the slope. It would be a good idea to re-cut or equip this passage, as was done, for example, for the crossing of the scree on the Bancs path (here it is much shorter).
- Although the "sentier de ronde" trail around Montagne de Chaudun is otherwise very well marked and very safe, it is worth noting that it includes passages that may be daunting for "people prone to vertigo", as the guidebooks say.

The only major difficulty is reaching the peak of the needle (a bit dizzying).

The route description is perfect. A beautiful hike.

A beautiful, fairly popular hike, as it can be adapted in terms of route and elevation. You can avoid the exposed sections at the top of the three peaks (alternative route below Pic de Gleize and optional access to the other two peaks) while still enjoying the surrounding views
.
