From Saint-Laurent-du-Pont, take the road towards Saint-Pierre-de-Chartreuse and after 1 km, take the small forest road towards the Charteuse de Curière.
Park in the large car park 150 m after the last buildings of the convent. Beyond this point, the road is closed to traffic.
(S/E) From the car park, take the beautiful track that starts on the right. This track climbs steadily through the forest to reach the Belvédère de Nonne viewpoint.
(1) From the viewpoint, continue for 100 m to find the signpost for 1200 m, with a cross hidden in the trees. Continue in a south-westerly direction and, after a short descent, the track ends and turns into a rocky path. Stay on the path and you will reach a junction.
(2) Leave the path and take a trail that climbs to the left (steep at first) and continue through the forest until you reach a scree slope. Cross it by following the trail to the left at the foot of the cliff and, once you have left the scree slope, you will reach Cul de Lampe (signpost Alt 1400 m).
(3) Continue climbing through the forest and then into increasingly open terrain until you reach a meadow (signpost 1490 m).
(4) Leave the path that climbs to Col de Charmille on your left and follow the meadow on the right, initially on a flat path. At the end of the meadow, the path climbs gently towards the clearly visible Col de la Sure.
(5) At Col de la Sure, you will rejoin the paths coming from Col de la Charmette and suddenly find yourself in much more company. Take the steep, winding, rocky path on the right. Allow 35 to 40 minutes to reach the summit (panoramic view).
(6) From the summit, descend to Col de la Sure. On the descent, take note of the path you will follow to make a circular route.
(5) From the pass, head left (north-east) towards Col de la Charmille along an almost flat balcony path. Shortly after reaching a more wooded area, you will arrive at Col de la Charmille.
(7) From the pass, turn right onto a dirt path, then a forest track that has been completely destroyed by logging equipment. Descend carefully along this track until you reach an intersection: the "dining room".
(8) Leave the track and take a path on the left. 100 metres further on, ford a stream and continue along a comfortable path until you reach an intersection with a small viewpoint over the Chartreuse de Curière.
(9) Then turn left onto a rocky path with numerous hairpin bends and come out onto a road.
(10) Turn left to quickly return to the car park (S/E).
