(S) From the car park at Saint Nizier du Moucherotte, head towards Les Trois Pucelles.
(1) Then head towards Tourbière du Peuil.
(2) You’ll come out onto a wide track suitable for vehicles; turn right uphill and continue, following the contour line.
Join a forest road.
(3) Take the path running along the ridge of the Col de l'Arc, known as the Pas de l’Âne trail. Turn right; the climb is quite steep, and you will reach the Col de l'Arc.
(4) Continue beneath the cliff to the Col Vert via the Sentier des Deux Cols (Caution: this section is a bit tricky, so take care!).
(5) At Col Vert, cross over to the other side (west) and descend to the Cabane de Roybon, the end of today’s stage (E).
