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).
