0/ Start: La Fétiuère. 1/ Follow the signs for "Chalets d'Oche". Cross the "Ugine" on a wooden bridge and head uphill. At the crossroads, turn right. At the next intersection, take the left-hand path. Climb this steep, winding path. Emerge into a valley and follow the "Chalets d'Oche". 2/ Continue towards "Lac de la Case". Turn left around the lake. Then turn left towards "Château d'Oche". 3/ Turn right uphill. Then climb steeply up a grassy spine, which requires great care. Continue along a narrow path. The path is not vertiginous, but you must not stray from it. Reach a collar on the right overlooking the Col des Portes d'Oche. 4/ Follow the path as it twists and turns through a vast pasture. Turn right to approach the ridge. Turn left to follow the ridge, while staying below. Pass a small natural stone arch and climb a small rocky corridor. At the exit, turn right and make a few short hairpin bends to reach the summit, on which two small crosses stand. 5/ The descent follows the same path. At the bottom of the grassy spine, ignore a path that goes off to the left to join the "Col des Portes d'Oche" path. 6/ At the fork in the road, turn left towards "Lac de la Case". Continue on to the Chalets d'Oche. Then descend the valley. Turn left to reach the wooden bridge. Follow the gravel path back to the starting point.
