Parking is available below the Chaillol Tourist Office at 1600.
(S/E) From the Tourist Office, take the track opposite and pass under the ski lift.
Head towards Col de la Pisse (GR® signposting) on the track on the right. Continue along the track, pass the signs for Coustaille and Lou Dévès, then continue straight ahead towards Col de la Pisse via the Cabanes forest road. When you reach the first sign for Les cabanes, turn right.
(1) Turn right and cross the stream to find another Les cabanes sign. Turn left towards Col de la Pisse on the yellow and red marked trail, which winds through the forest on a gradual but not too steep climb.
(2) Reach the Grande Baume crossroads and continue right towards Col de la Pisse. 300 metres further on, at a crossroads, turn left. The trail climbs to Col de la Pisse, which offers a beautiful view of the Champsaur valley.
(3) From the pass, turn right onto the stony path and follow the old Mal Cros canal for a while. There will then be no more signposts, just cairns. Try to follow the cairns and the numerous and varied tracks, which all lead to the Col de Côte Longue. This section is very stony in places, but higher up it rejoins the old canal and arrives at the Col de Côte Longue.
(4) From the pass, take the path on the left indicated by a sign for Le Vieux Chaillol. Continue climbing for about 500 metres to reach La Cabane des Parisiens, the last barrier before the summit.
(5) Turn left at the hut and begin the climb to the summit. It is quite difficult, as there are many cairns and traces that are more or less visible at times, but also many rocks and stones. You will need to find a way through, trying not to follow the cairns that go to the left, but rather those on the right.
The summit section is easier and, once you reach the summit, there is a small shelter on the left with a hiding place for the guest book. A few metres further on, the true summit (3,163 metres) offers breathtaking views.
(6) Descend by the same route (if you can find the same cairns) or by another trail to La Cabane des Parisiens.
(5) From the hut, turn left onto the path along the mountainside that passes the remains of the canal and leads to Lac de Mal Cros.
(7) From the lake, return to La Cabane des Parisiens.
(5) Descend to the Col de Côte Longue (4) and then to the Col de la Pisse (3) via the same route as on the way up. Begin the descent towards Chaillol Station - Le Chevalet, still following the same path as on the way up.
(2) At the Grande Baume junction, turn right towards Le Chevalet and continue downhill.
(8) When you reach the Le Chevalet junction, turn left towards Chaillol Station - Les Cabanes. The descent continues along a beautiful forest trail and returns to the Les Cabanes crossroads.
(1) Turn right onto the track that leads back to Chaillol station and the car park (S/E).
