From the parking, go up the road for 200 m until the post "Montchaffrey". Turn left on the Oeilly path which goes up in the forest and joins a wide track. Shortly after the post "Fontaine du Mulet", turn on a path that goes down and continue on a small road that leads to the site of the old chartreuse de Prémol [Ruins and forest house, place of relaxation and picnic]. Continue until you reach the road to Chamrousse (D111). Go along it for 80m and take on the left (caution) a path that rises above the road, intersects it higher [caution] and leads to the post "l'Exutoire". [It is possible to walk around the Luitel lake on a discovery trail passing by the park house 400m to the south. Respect the regulations of the Nature Reserve and the indications on the site]. From then on, the itinerary follows the GR®738 Haute Traversée de Belledonne for more than 5 km on a wide forest trail. Shortly after the baraque Pagnot, turn right on a downhill path. Turn left under the high tension line. The path is quite steep and leaves the forest to reach the Madeleine pass [orientation table for the panorama extending from Taillefer to Vercors]. Continue to the right on the track between the meadows until the post "la Croisée" where you leave the GR®738 by turning to the right in direction of Montchaffrey. At the post "Chenevier", take on the right a very stony path, pass the millstone, vestige of the mill of Chenevier and go up to arrive on a beautiful path lined with big stones in sight of Montchaffrey. Join the parking lot.
