The ascent to the plateau can be made either via Oz-en-Oisans, taking the Poutrans 1 and 2 cable cars, or via L’Alpe d’Huez via the DMC cable car.
(S/E) Head down towards the mountain restaurant. Follow the pedestrian signs.
(1) Pass the restaurant on your right and take the footpath on your left. Do not take the cross-country ski trail.
Cross the footpath and head off-piste up the ridges overlooking the cross-country ski trails.
Continue along the ridge, passing between the snow-covered Lacs Noir and Besson.
(2) Descend towards the end of Lac de la Faucille and climb straight up the slope heading north. Be careful of the thickness of the ice; if in doubt, take the track that goes round the lake.
(3) Tackle the steep but short slope. Then head towards the Falaises des Roches, heading south-east. You’ll reach a wide, open track.
(4) Either traverse along the track – though this is rather awkward in snowshoes – or take the track.
(5) Pass at the foot of the ice falls and complete the circular route by staying at altitude for as long as possible. Then descend towards the Poutrans 2 resort via the ski run.
(1) Continue to the Poutrans 2 station (S/E).
Take the cable car back to Oz station.
