Start at the bottom of the Semnoz ski lift (altitude 1,478 m).
(S/E) Follow the snowshoe trail southwards to the edge of the forest.
(1) Enter the forest, where the slope becomes steeper and the path narrower. Make small turns (good powder snow on this day). At the edge of the forest, continue south, cutting across the slope until you reach the ridge near the alpine chalets (altitude 1640 m).
(2) Pass near the Chalets de Leschaux and under a chairlift, but stay on the ridge (on your left, the downhill run). Continue south-southwest to descend towards the Chalets de Gruffy.
(3) From the Chalets de Gruffy, head east towards Crêt de l'Aigle (altitude 1,646 m).
(4) After a short break at the summit, descend northwards then climb back up towards the ridge to find yourself at the same altitude as on the way up, around 1610 metres. Pass under the chairlift again and head towards the Chalets de Leschaux.
(2) Stay on the ridge line towards Crêt de Chatillon (north-east direction).
(5) Once you reach the highest point at 1702 m, descend towards the forest (still north-east) to find the cross-country ski trail that takes you to the road (narrow and slightly steep passage).
(6) Take off your skis to cross the road and then continue along this trail, which descends into the forest and takes you back to the start (heading north then west). (DA).
