Le Roc d'Enfer

Drive to Graydon (about 1,340 m) above Saint-Jean-d'Aulps, reached via Les Gets from the south or Saint-Jean-d'Aulps from the north. Behind the chapel, leave the track that goes right towards the Col de Graydon and head straight across the fields towards a path visible on the hillside (only vague waymarks at first). At a level area, leave the path to the Col Ratti on the left and keep right; at the next fork choose either the traversing path (steep, slippery side-slopes in places) or the steeper direct line. Both lead to the Brèche de la Golette, a notch in the ridge at about 1,971–1,992 m, approached on slippery ground; warning signs stand at the notch. From the notch, turn left onto the path along the crest. It is steep and exposed in places, with sections where hands are needed and rock that stays damp on this side, up to the north summit (Pointe Saint-Jean, 2,209 m). The ridge then dips and climbs again to the main summit (2,244 m); this last section is airy and should be avoided in rain or strong wind. Allow about 2½ hours up and 2 hours down by the same route. The Roc d'Enfer has a bad reputation for accidents: the slopes are steep and high on all sides and a slip can be fatal. Go only in dry weather with good boots. The longer full traverse of the ridges from the Col de Foron (T4–PD, fixed chains in places) is better climbed in that direction than descended.
