Hike to go from Vaulnaveys-le-Haut to reach the National Nature Reserve of Lake Luitel on the foothills of Belledonne, for seasoned hikers.
The start is near the Café du Centre in Vaulnaveys-le-Haut, taking the Chemin des Chartreux.
Gradually, by gaining altitude, we discover the many meadows occupying a terrace: the Rinjat plan at an altitude of 550m, from where the point of view is already very clear. The path climbs up and skims the road to Chamrousse at the level of the laces of Montgardier and Fujarey.
The route then turns south and becomes forest. Beeches and spruces are everywhere. Continue the forest ascent to Prémol, at 1080m, pass near the remains of the old Chartreuse. Then cross the Chamrousse road for the first time, then a second time to stay downstream from the latter to Lac du Luitel at an altitude of 1250m, the end of the ascent.
Arriving near the chalet of the nature reserve, it is possible to picnic on tables, but also to learn about peat bogs to discover sphagnum mosses, carnivorous plants, hook pines, dragonflies and many other natural curiosities.
The departure by the discovery path on slatted floor will allow the observation of this complex and fragile ecosystem.
The descent will take place on a wide and comfortable track with beautiful views of the Vercors, the Chartreuse and the Grenobloise conurbation. Further down, hikers will cross the charming hamlet of "Montchaffrey" then join the hamlet "Les Roberts" lower down.
Then go down to the Alloues. The descent will take place between meadows and forest, then join a small road at Les Meynards ”.
At the "Les Meynards" post, turn right and then reach the starting point by a small road: "promenade de la mondée", then by the route des penitents blancs and finally the chemin de prè'abé.
