Walk in the Jean-Jacques Rousseau Desert - Les Vouillants

The perfect family walk: easy, fun, with trails that all lead to the same place, Pré Faure.
This circuit is unique in that it passes through the "Désert Jean-Jacques Rousseau", worthy of the greatest romantics, climbs up to the Ferme Froussard, a historic site linked to the Resistance, and returns via a viewpoint offering a superb view of Grenoble and its valley.
More challenging access from the town of Fontaine via the "Coup de Sabre"

Description of the walk

Access: Drive from Seyssinet to the new car park, avoiding the hairpin bend (the usual access route to Les Vouillants) and the Désert de l'écureuil (Resistance memorial). This recently built car park is impossible to miss on your right, opposite the Château de Beauregard.

(S/E) From the car park, head north towards the undergrowth 30 metres away to reach the entrance to the Parc Jean-Jacques Rousseau, protected by a wall with a large brown gate.

At the park entrance, there is a sign on the wall inside the enclosure: "1.20 km, le Pré Faure". It is best to follow the path on the left, as the views are prettier. However, all three paths lead to the same crossroads.

(1) At the bottom of the descent, you will arrive at a crossroads of wide paths, with a green barrier about 100 metres ahead. Turn left and go downhill. A little further down, stay on the widest path, leaving the small paths on the left and right. A few posts about 1 metre high support a white sign with yellow arrows. Follow these few yellow arrows and the yellow paint marks on the trees.
Go up this wide path called Chemin du Génie for about 1 km until you reach the Froussard farm, which was destroyed during the Second World War for acts of resistance. Be careful, as there are beehives here during the season. Do not approach them.

(2) 50 metres above the farm, you will find yourself at a crossroads of paths at an altitude of 480 metres. Take the road downhill on the right, signposted "Parc Karl Marx 3.20 km - Les Vouillants 1.80 km".

(3) At the bottom of this new 450-metre descent, you will find a sign for "Pré Faure 0.95 km". Go slightly uphill opposite to reach a new barrier with a shooting range.

(4) Follow the road to the right and go up towards Pré Faure on this partially paved road, passing above the Raymond Farm.
At the fork, turn right. A few hundred metres further on, you will arrive at the Pré Faure car park: stay on the path until the next crossroads. Turn opposite, where you will see a signpost on your left, slightly hidden, indicating "Seyssinet Village 3.10 km - Désert J-J Rousseau 1.40 km".
Go back up this path above the "Désert de l'écureuil". During the climb, avoid the only path on your left and follow "Seyssinet Village 2.40 km - Désert JJ Rousseau 0.70 km". Go up to a beautiful open space and leave the path to cross over to this one.

(5) Enter this area overlooking Grenoble, with the Saint-Nizier road below. On your right, there is a path that climbs back up to the main path you have been following. If you are unsure, go back to the path you left.
Continue along this path back to the barrier. Avoid it, as the path literally drops down onto the paved road. Instead, climb the path on your right, which leads back to the car park where you started (S/E).

Waypoints

  1. S/E : km 0 - alt. 452 m - Parking near the Château de Beauregard
  2. 1 : km 1.1 - alt. 417 m - left at the bottom of the descent
  3. 2 : km 2.17 - alt. 482 m - turn right at the crossroads
  4. 3 : km 2.58 - alt. 395 m - Bottom of the descent
  5. 4 : km 2.88 - alt. 402 m - Go back up the partially paved path
  6. 5 : km 4.45 - alt. 442 m - View of Grenoble
  7. S/E : km 4.9 - alt. 452 m - Parking at the Château de Beauregard

Notes

Sometimes very busy during the summer.
There are no water sources, so bring light equipment such as trainers or mid-range hiking boots. The only slightly unusual section isbetween 2 and 3
There are benches and areas for resting, picnicking (fires are prohibited) and playing throughout the area.
If you are unsure about crossing from (4) to Pré Faure on this road frequented by cars, turn at the bottom of the descent (3). This will take you back to (1) along the fields. Once you reach (1), go back up to the Pré Faure car park or cross the hill via any path to reach the return trail.

Worth a visit

All along the descent from the Parc du Désert Jean-Jacques Rousseau, enjoy the information panels about the flora, fauna and geology.
Above you, you will see the "La Tour sans Venin" radio relay station several times.
The more adventurous can climb up from Fontaine via the "Coup de Sabre", a geological curiosity. Regulars climb up this way, turn as indicated in the description and (2), climb back up towards "la Ferme Durand" (2.65 km) to descend to Sassenage (8.66 km from this point). A beautiful, long walk already described on Visorando.
This is a place of resistance, so do your research beforehand to make the most of your visit to the Froussard farm: only ruins remain. Be careful of the beehives and do not approach them, as the bees will defend themselves and we must respect the work of the beekeepers.

A relaxing route with no difficulties (completed in dry weather). Very wide, well-maintained paths. Lots of trail runners and joggers out training. Probably very busy in summer and at weekends as it is mostly shaded. Beautiful view of Grenoble and the surrounding area at the end of the route. Note: drinking water and toilets at the start and end of the route. Rare...

A fairly shaded loop that is easy to access.
The path is fast-going and suitable for brisk walking/trail running.
Very pretty views of the Y Grenoblois and the mountains.

A classic and easy walk near Grenoble.
It offers beautiful views of Grenoble and its suburbs with the mountains in the background.
Please note that there is a steep, stony descent of 200-300 metres in the middle of the walk.
There are picnic areas.
Ideal for children! Or amateurs like me.

Thanks for the route!

Parking is not very busy at this time of year (outside French school holidays). Toilets at the start. Very pleasant, well-signposted route. Stunning views over the Grenoble conurbation.

A very beautiful walk; we do it regularly two or three times a year, changing the route depending on the weather; either the loop to the Froussard farm or via the tower without venom and back to the Vouillants
accessible to all

I was charmed by this lovely, very accessible walk. I particularly liked the section at the start of the hike through the Jean-Jacques Rousseau Desert, which is a really pleasant and unusual setting.

I have lived in Grenoble for over 30 years and had never set foot in Les Vouillants! I had a very negative image of the place, which used to have a reputation for being dirty and "unsavoury"!
In fact, it's nothing like that (absolutely nothing)! Not only is it clean, but it's also very pleasant and fun, thanks to the information panels explaining the different sites and ecosystems you come across.
There are lots of signposts at the crossroads, but it's best to know the area and where you are to find your way around!
A very beautiful, easy walk that is accessible to all and perfect for a half-day outing. I can imagine that it must be very busy on weekends and during the holidays...
