Parking in the main parking in Névache (The road is normally shut from here in early winter). Follow the closed road now a ski de fond track, as it heads uphill to a small plateau with a chapel, as the road starts to lose height you ski off south-ish to the bridge at 1749M. Follow the tracked path up to the Chalets du Buffere. Head along the GR57 a short way and then bare west towards the 2170m point, from here head NW up the easier angle slopes to the Crête de Baude.
Ski back the same way, after the Chalets Buffere you can stick to the tracked path but this is very steep in places and not very wide, it is easier to stay in the trees near the path. Once down at the bridge at 1749m its easier to walk or skin back up to the ski du fond track
