Long loop of the Gobert trail

The Gobert trail is very popular with hikers for its rich flora, which can be discovered all along the way between the Pic Saint-Michel crossroads and the Roybon hut. This almost horizontal section also offers a remarkable view of the Vercors plateau between Lans-en-Vercors and Villard-de-Lans.

Description of the walk

Park in the Conversaria car park.

(S/E) Leave the car park on the left and follow the sign for Col de l'Arc. Then take a wide track marked Vert Jaune, enter the woods and head for the Machiret fountain on the right of the track.

(1) Continue and begin a steeper climb, finding the Issarts trail at the cattle park. Continue to the right, following the green and yellow markings, and you will reach theGR® Tour des Quatre Montagnes crossroads.

(2) Take it on the right; this is the start of the Sentier Gobert. Now almost level, walk along the balcony path. After a very short climb, you will reach the Combe de Chaulange crossroads.

(3) Continue on theGR® trail, leaving the path through this valley on your right. At the place called Les Côtes, you will come to another trail junction that takes you down to the Croix des Plâtres.

(4) Stay on the GR® trail. Now walk through the woods and follow a remarkable path to reach the Cabane de Roybon.

(5) Begin the descent along the track that follows theGR® trail, leaving it at the junction of two tracks and keeping to the right (signposted Les Plâtres). Pass the Fontaine Magdelen fountain and a few metres further on you will come to another junction of tracks.

(6) Stay on the right-hand track, pass the Les Cochettes sign and continue to the right. When you reach the road, turn right again to return to the Conversaria car park (S/E).

Hello and thank you for your message. However, I would like to point out that you rated the ease of following the route as "moderate". This is understandable, given the snow that fell during the night and the conditions you encountered during your hike. This hike was described following a visit in the spring, and I can assure you that the route is particularly easy to follow and presents no difficulty whatsoever.
Have a nice day and enjoy your future hikes.

60cm of snow had fallen during the night, completely blocking the path, with tree branches bending down to the ground.
We were alone, completely alone. At one point, we had to turn back, faced with a wall of snow and sinking more than a metre despite our snowshoes. It felt like the far north of Canada in our beautiful Vercors. It was magical.

I recommend this fairly easy hike with a few exposed sections but on a fairly wide trail. You still need to be careful when walking.
I would not recommend it if the trail is slippery due to bad weather or if you have young children.
Beautiful views!

This is a hike that should be described as not recommended for people who are afraid of heights, as some sections are very vertiginous.

Hike done in beautiful sunshine. Easy to follow with very good signposting.
The hillside trail is a bit dangerous, so watch where you put your feet. Be careful with children as there are steep cliffs in places.
Otherwise, beautiful views of the Vercors

A very pleasant walk in a fantastic setting. The Gobert trail is very easy to follow and the view is splendid. I completed this route with a return trip to Col Vert, which was a little more difficult going up but really beautiful.
Many thanks for this very well-marked route.

A beautiful loop with lots of people until Combe Chaulange, where hikers descend via the alternative route leading to Conversaria. After that, there is no one else until Roybon's cabin in the forest. The path is very slippery. From the cabin, we saw quite a few people descending and ascending. We arrived at the car park just before the rain forecast for 4pm. Otherwise, it was a beautiful hike.

Very pretty Gobert trail with a balcony view where I could admire the view of the Villars de Lans valley and a few chamois. Easy hike, gentle climb, half flat, half in the woods. Hike done in April, the little flowers were missing!

A beautiful hike on the Gaubert trail, overlooking Villard de Lans. No particular difficulties on the route described. We added the climb to Col Vert from the Roybon refuge, which makes it more difficult as the slope is steep. Unfortunately, the summit was shrouded in mist! In clear weather, there is a beautiful view of the Grenoble valley and the Alps from the pass.

A magnificent, very easy walk. There is a short climb at the start, but it is easy and steady. Then you follow the contours of the land, admiring the scenery. There are few other walkers. It is very windy on the plateau, but most of the walk is sheltered.

The trail is very pleasant and lined with willowherb. The view is unobstructed in some places and offers a beautiful panorama.
Please note: one of the fields is bordered by a plastic mesh fence, which is a real trap for small deer. We found one struggling, completely tangled in the mesh; it was strangling itself. We managed to cut its bonds and free it. This type of fence, which I had never seen before, should be banned.

A very beautiful hike with magnificent views of Villard de Lans and the surrounding mountains. We did it in 4½ hours, with several short photo breaks and a picnic stop.
There are a few tricky sections (scree and some steep slopes) but otherwise it's a very pleasant hike with plenty of shade, which is very welcome in hot weather.
Only the end of the hike after the Roybon hut to reach the Conversaria car park is not very interesting, on a stony path that is not very pleasant.

Given the lack of snow this year (2024), we decided to hike on foot and leave our snowshoes at home. We did this hike on 25 March without any problems. And what a wonder when we spotted a group of chamois in the Chaulange valley. This balcony trail overlooking Villard-de-Lans is very pleasant and does not present any particular difficulties.
