The Saint Eynard ridge and the Pré du Plat

A short and easy walk on the ridge of Mont-Saint-Eynard, above Grenoble, offering beautiful panoramic views of the city, the Belledonne mountain range and, at the end, the Sappey valley. This walk is a local classic and can be very busy.

Description of the walk

You can reach the start of the walk by taking a small road that leaves from the entrance to the village of Sappey-en-Chartreuse when arriving from Grenoble and leads to the Fort du Saint-Eynard (signposted).
Park in the small car park 200 m below the fort. A discreet P sign indicates that you should take a small road on the left.

(S/E) Head east towards the rock face. Take the wide rampart walk on the left. Enjoy the view of the city of Grenoble and the meandering Isère river. Reach the end of the rampart walk and note the cave there.

(1) Turn left and climb a small hill to reach theGR®9. Continue to the right, following the red and white markings along the cliff.

(2) Pass Pas Guiguet (sign indicating the direction of Pré du Plat). Stay on theGR® along the ridge. At a fork, turn right.

(3) When you reach the Pré du Plat sign, descend to the left (towards Le Sappey). You will come to a wide track, which you take to the right. This takes you off theGR®.
The track leads you to the top of the Grand Sommard ski lift at a place called Pré du Plat. Enjoy the view of the Sappey valley and the surrounding peaks (from Bec de l'Orient on the far left to Chamechaude on the right).

(4) Return via the same route. Be careful not to pass theGR® on the left. The junction is very discreet. Climb up the embankment.

(3) At the "Pré du Plat" sign, turn right to return to the fort car park (S/E).

Notes

The road to the fort is not cleared of snow in winter. The walk is therefore only accessible after the snow has melted and... before the next snowfall...
There are places to eat at the fort (check opening hours carefully).
Accessing the ridge by car limits the amount of climbing involved.
Although the walk is easy, you should still be careful:
- although the path is separated from the precipice by an embankment and vegetation, there are several points where it runs right up to the edge. Keep a close eye on any children with you. In principle, there should be no problems with vertigo.
- The trail encounters several sharp limestone pavements, which can be slippery.

Worth a visit

(S/E) When it is open, you can enter the Saint-Eynard fort and visit its restaurant
(1) You will have beautiful aerial views of Grenoble and the meanders of the Isère River.
You will also have a panoramic view of the Belledonne mountain range and the Taillefer.
(4) Pré du Plat: enjoy a beautiful view of the Sappey en Chartreuse valley with:
- on the right as you look down the valley, the magnificent Chamechaude,
- on the left, a wooded cone: the Ecoutoux
- on the far left, the Vercors and the Bec de l'Orient.

A lovely walk. Sometimes the ridge line is shrouded in mist, so choose your day carefully.
The cliff is close and the drop is impressive. Watch out for animals and children.

A pleasant hike. The view of the Grésivaudan valley and the Belledonne mountain range is magnificent. Lots of shade, so perfect when it's hot.

A walk at the end of March with elderly people who are not used to walking, which took us a little over two hours there and back. The weather was on our side, allowing us to enjoy the magnificent panoramic views of the valley. The path was a little muddy but also surrounded by flowers: splendid! I will definitely be back! And thank you for the very handy app.

Hiking on a Tuesday outside of the holidays, no one on the trails.
Ascent from Le Sappey-en-Chartreuse via a path that starts at the church and leads to the ridges at point 3 of the description. Once at the top, the landscape is magnificent. We wind our way between the edge of the forest and the cliff edge. Exceptional panorama.

Today's hike took place in very favourable weather conditions: beautiful sunshine and clear skies offering fantastic views from the Vercors to Mont Blanc.

I set off (on foot) from Col de Vence on this hike, which I extended with this one.

At the point (3), I continued straight on along the ridge path to reach the summit at 1,371 metres for a beautiful view of Mont Blanc and the Dent de Crolles.

Another suggestion: go around the fort on the right to reach the end of the trail coming from Col de Vence and take the trail on the right for about a hundred metres to the Croix de l'Izon. There is no cross, but there is a beautiful view of Le Sappey and Chamechaude.

Thank you for taking the time to leave your review.
Regarding snow cover, the practical information states that this walk is only accessible outside of snowy periods.
I don't quite understand why you say that the route on the map is not very reliable. Could you tell us more?
Thank you in advance. Happy walking.

We only made it up to the ridge (our car was stuck in the snow) and did the very beginning of the hike.
Beautiful view of the valley, only the town was in the fog, which made for a beautiful natural landscape.

In winter, the Fort de St Eynard is closed and the snow clearance service does not clear the road. They have also placed a pile of snow at the bottom of the road to restrict access. Once we had got around this pile, we found that the road was no longer passable from the second bend onwards.

Very surprising, I went there three weeks ago...
Could it have snowed again since then, at that altitude...
Good luck next time.
