Description of the walk

The start of this route is at Les Signaraux above the small village of La Motte d'Aveillans (about 35 km from Grenoble towards La Mure on the D529). Les Signaraux is a small family ski resort with two or three ski lifts and cross-country ski trails that wind through the mountain pastures. The route starts from the car park located at the ski lifts, so do not stop in the hamlet, as the hike will be a little longer from there.

(S/E) From the car park, join a wide path below the ski lifts (signposted). This path is almost flat at the start, even descending slightly, then after about half an hour on this alpine path, which climbs gently southwards, you will arrive at the foot of the Col du Sénépy.

(1) Turn left, the slope becomes much steeper and you first climb up a path, then through the mountain pasture to the Col du Sénépy (1,526 m), where there is a refreshment stand for cows.

(2) To reach the summit of Sénépy, a very wide track winds its way southwards. It is not advisable to take the shortcuts that seem obvious, as they contribute to the degradation of the mountain pasture by accentuating erosion due to the fairly steep slope.

(3) Once at the summit, enjoy the 360° view of the entire region, including Trièves, Oisans, Taillefer, Belledonne, Chartreuse and the entire Vercors mountain range as far as Mont Aiguille. You can also see the magnificent Monteynard dam lake on the Drac river.
To return, descend to the Col de Sénépy.

(2) Take the path through the mountain pastures that more or less follows the summit ridge towards the east. Pass the summit of Serre de l'Horizon and continue along Serre de la Combette. The path turns north until it reaches a fork.

(4) Keep right, heading northeast, and reach the summit of Pierre Plantée (1,559 m).

(5) Enjoy the view, then return to the previous fork.

(4) Continue right downhill towards the north-west, cutting across a bend in the track and then rejoining it below (elevation 1,421 m). Turn left and rejoin the path taken on the way up. Continue downhill and return to the ski lift car park (S/E).

Notes

The route is marked (small yellow signs) and it takes about two hours to reach the summit and climb the 550 metres of elevation gain.

Very important: this mountain pasture is occupied by numerous cattle. Please respect the fences, use the designated passages for hikers and close the gates behind you. The farmers share this place with hikers for our enjoyment, so please respect their work.

Worth a visit

From La Motte d'Aveillans, on the opposite slope, you can reach the Pierre Percée, one of the seven wonders of the Dauphiné, the subject of a legend featuring the Constable of Lesdiguières and the Devil (brrrrr).
Also worth noting are the Laffrey lakes (about 10 km away) for a session of pedal boating, rowing or simply swimming if the weather permits.

This hike is simply magnificent!

The views from the pass or the summit are sublime! A breathtaking 360° panorama of beauty!

Be aware that there is very little shade on sunny days. There are several routes, with flat sections and some fairly steep climbs in places. The paths are narrow in places but mostly quite wide.

I said it was very busy, but I did it on a Sunday in October when the weather was glorious and therefore an ideal day for hikers... but in the end, it wasn't that crowded!

Walking at my own pace, rather leisurely and contemplatively, I left the Signaraux car park at 10.15 a.m. and arrived at the summit at 1 p.m., with breaks and chats with other walkers...

Very beautiful route, with 360° views of all the surrounding mountains (Vercors, Chartreuse, Dévoluy, Écrins, etc.). However, it is very windy, so remember to bring a windbreaker.

A superb walk among the cows. Unfortunately, it was overcast, with almost no visibility, and the clouds and cows in the middle of the paths made it a little difficult to find the right trail at times.
To be repeated on a clearer day!

Did it "backwards". Pierre Plantée, crêtes, Sénepy via the switchbacks, then straight back down the slope and back to Signaraux. Quite a lot of snow. Started with crampons, then switched to snowshoes. Easy route. More people at the top, some with paragliders.

Magnificent 360-degree view from the summit, and the return trip along the ridges and stone formations was also very nice.
There was a slight hesitation in finding the way down at the top of the ski lifts.
The trail markers are helpful! You also need to be careful at the very end of the hike and not get carried away by the path descending to the left, but stay on the one that remains level until you reach the car park.

Hello, the only problem is that there are no signs at the car park indicating which direction to go to head south.
Best done in good weather as there are beautiful views from the summit and on the way back via the Pierre Plantée.

A beautiful route, winding through wide mountain pastures enlivened by the incessant music of cowbells.
No technical difficulties. However, overnight rain had turned the dirt tracks into mud in places.
From the summit of Sénépy, reached in two hours, the 360-degree panorama is remarkable.
On the way back from the summit, when you reach the pass (checkpoint 2), take the path that follows the ridges as closely as possible, heading east. If necessary, use the GPX route on the Visorando app to make sure you're on the right track (which is what we did).
At waypoint 4, visibility was poor, so we did not climb to the summit of Pierre Plantée. Instead, we abandoned the path and returned to the car park by descending straight down the ski slope, which shortened the return route slightly.

Thanks to Polo381 for posting this enjoyable hike online

Beautiful hike, gradual climb, superb landscapes, lots of flowers including magnificent blue gentians. Bring a windbreaker as it is windy at the summit.

Very beautiful hike. Easy. Starts in the forest, then passes through pastures, sometimes occupied by herds of cows. Not much shade. At the summit, magnificent view to the west over the Vercors and Lake Monteynard, and to the east over the Oisans. Ideal hike for autumn (even if it's still warm)?

A very beautiful walk, easy and enjoyable.
The approach through the woods is a bit long.
Magnificent view from the summit.
The only problem in my opinion is the large number of paths, which can sometimes make it difficult to find the right one. Fortunately, the Sénépy is visible from a distance, so you can't go wrong.
