From Les Barnets car park, head towards the Pic Saint-Michel by following the 'GR® de Pays', 'Tour des Quatre-Montagnes' (yellow and red markers). At the Collet du Furon, take the path up to Combe Oursière, and follow the yellow-and-green markers from then onwards. The path continues, winding between the boulders to end up at the Pic Saint-Michel, which offers views over the Grenoble valley and the Alpine mountains.

The hike continues just below the ridge, descending steadily to eventually join the Col de l'Arc. Keep descending until you reach Font Froide, then take the 'GR® 9' path (white-and-red markers), to end up at Salière and the Collet du Furon. From there, head back to Les Barnets car park via the path you took at the beginning of the hike.
