Park at the Col du Pré (1,703 m).
(S/E) Cross the road, then take the path on the right, which is also a botanical trail. Follow it for about 1 km until you reach a junction.
(1) Leave the botanical trail to your left and continue along the undulating path, which now offers beautiful views of the Arêches valley. You will reach another intersection.
(2) Leave the path and take a dirt track on the left, passing above a chalet. The path is well marked, with several sections laid with wooden decking. After crossing some wet areas, the path becomes a track again. You will reach a Y-junction.
(3) Take the left branch; the route now begins to climb. Follow a few switchbacks along the track, then, after a fork that leads to a chalet, continue climbing along a winding path. Along the way, ignore a path on the right that descends to Lac de Saint-Guérin, then reach the Passage de la Charmette.
(4) The route now continues northwards, facing Mont Blanc. Take a track on the left and leave it shortly afterwards for a path on the left that follows the ridge. The path climbs a little at first, then descends and climbs again to reach the highest point of the circuit at Roche Parstire.
(5) Begin the descent, still facing Mont Blanc with the Roselend dam lake below on your right. The dirt trail can be slippery in wet conditions. It gradually moves away from the ridge. Pass a cubic stele, enter the forest briefly and return to the car park at the pass (S/E).
