Access via the CD916 from Saint-Genix or Novalaise. Park at the Chenevières car park (orientation table), above Ste-Marie-d'Alvey, 200 m below the Col de la Crusille.
(S/E) Head north on the path opposite the upper entrance to the car park and follow the switchbacks. Before reaching the power line (deforested area), take a path on the right which, after a threshold, descends to the northeast, passing under the power line. It leads to a major crossroads directly above the Gerbaix road.
Alternative: it is also possible to climb from the path opposite the lower entrance to the area and join the same crossroads.
(1) Take the second path on the left: well paved with stones, it climbs north-west to join the Chenevières ridge and turns right to follow it to a pass on the edge of the forest.
(2) At this pass, leave the forest path and climb up to the right on a path marked by a cairn. It climbs up the steep slope to the summit of Pierre des Millières.
(3) Walk along the summit ridge and, at its end, descend the steep north ridge. Once back in the forest, turn left to reach a forest crossroads.
Alternative: if the descent down the north ridge equipped with handrails seems too steep, descend from Pierre des Millières via the ascent path to the previous pass and turn right to reach the crossroads at the same level.
(4) Leave the path heading west towards the ridge and take the next path on the right heading north-west. This path winds its way through the daffodil-covered hills, passes below the summit (altitude 751 m), leaves a few paths on the right and then on the left, continues in the same direction and descends to a flat area that has been deforested and is now replanted.
Cross this planted area to reach, either upstream or downstream, via a small ramp, a good path coming from the right, from Gerbaix.
Take it on the left, level with the hillside, and go around the Rocher du Gendarme to join a marked path descending from the Col de la Lattaz.
(5) Take it to the left, heading south, and descend, continuing straight ahead at each junction, until you reach a drinking water reservoir.
Turn left, south-east, onto a gravel road that leads back to the CD916, which you must follow for 200 m to reach the car park (S/E).
