1/ Take the track to the left of the stream through the hamlet of Bise, without crossing the bridge. After a flat area, the track splits in two (at a place called "la Salle").
2/ Turn right towards "Col de Bise" (GR5).
3/ At Col de Bise, head for Col de Pavis. Go around the "Pavis" and down to an intersection. The terrain is uneven, and you need to cross a few small gravel pits. Climb left towards the pass.
4/ Descend to Lac de Darbon. Go around the lake to the left and take the path rising to the left towards the Col de Floray. Follow the ridge and plunge left. The slope is steep.
5/ Then follow the pastures at the start of the hike to reach the Bise chalets.
