From Nantes-en-Ratier, follow signs for La Valette on the D114. At the Col de Malissol, turn left towards Le Poyet, ignore the first junction (on your right) and park at the second junction.
The starting point has parking for 2 or 3 cars. If this is not possible, there are other parking spaces available in the vicinity.
(S/E) After passing through the ONF barrier, follow the track all the way to the Cabane du Poyet. There are no markings on the track, but the route is very clear.
(1) Veer slightly off the track to your left and admire the panoramic view of the Matheysin Plateau, the Vercors range and, on the far left, the Dévoluy.
Continue the climb along the track.
(2) At the Cabane du Poyet, you can top up your water bottles, visit the chalet and enjoy the peace and quiet of the spot.
When you set off again, in front of the hut, take the yellow-marked path straight ahead, ignoring the one leading down to the left. Follow this path as it climbs all the way to the Col de la Grangette.
(3) At the Col de la Grangette, at the Fontaine de Bigasset, take in the 360° views.
The return journey will be via the south-facing downhill path (signposted “Les Aigles”). This route is particularly steep and requires good footwear (at least mid-cut, if not high-top) to protect your ankles; descend until you rejoin the track taken on the ascent.
(1) There are then two options for getting to (S/E):
- take the return route via the main track used on the way up, which is slightly steep.
- take the direct route, which is quite steep.
