Start: Take the Aiguille du Midi cable car down to Plan de l'Aiguille, either directly from the valley, or after a climb to the Aiguille du Midi.
(S/E) Turn left from the Plan de l'Aiguille restaurant, and take the path heading North-West.
(1) After about 300 m, turn right and continue along the path, which winds downhill, then uphill. Keep heading North-East, leaving the paths to your left and right.
(2) Ford the torrent de Blaitière and continue straight ahead until you reach an intersection.
(3) Leave the path on your left, go straight ahead and cross the Torrent du Grépont. Then continue straight ahead until you reach a junction, 1 km away. At 2098, take the right-hand path.
(4) At the next intersection, you have two options:
- Continue straight ahead on a narrow, overhanging path to the Hôtel-restaurant du Montenvers.
- As shown on the map and recommended, turn right and wind up the hill. Continue North-East along the edge of the plateau to the top of Signal Forbes.
(5) Continue downhill, with large switchbacks, to the Hôtel-restaurant du Montenvers.
(6) Turn right onto the local road to the Montenvers-Mer de Glace station (S/E).
