Start at the first junction on the D538, after leaving Dieulefit, heading towards Bourdeaux, at the Source du Jabron campsite, on the right (Chemin du Brachet). Park in the car park next to the recycling bins.
(S/E) Take the D538 uphill and join the Chemin de la Calade at the second hairpin bend on the left.
(1) Take the track on the right and follow it to the junction at the Col de Ventebrun.
(2) Continue right on the D538, towards Bourdeaux, until you reach the Col de Boutière.
(3) Take the path on the right. At the three-way junction, keep left, leave the woods (view of the Col de la Chaudière, the Trois Becs and the Montagne de Couspeau) then quickly turn right and continue through the undergrowth.
(4) At the four-way junction, take the path straight ahead. This becomes a little rocky but then easier on the descent. At the small road, continue downhill to the left and, at the end of Chemin de Grimolle, turn right until you quickly reach the next junction.
(5) Turn left onto Chemin de la Motte and continue uphill to the farm, at the end of the tarmac.
(6) Pass between the buildings and, immediately afterwards, take the path on the right, uphill. Follow the ridge line until you reach a road junction.
(7) Continue straight ahead on the D223 towards Vesc, for a return trip to the Col de Vesc.
(8) After taking in the views, return to the previous junction.
(7) Continue on the D223 towards Comps until you reach the second left-hand turn, Chemin des Combes.
(9) Take the hairpin bend onto this track, then continue along a path near the Refuge des Combes. After a winding descent, you’ll reach a road with a picnic table on the left.
(10) Turn right and follow the D547 until you reach the Romanesque church at Comps, after turning left onto Chemin de l'Église.
(11) Continue along the track and, at the bottom of the descent, turn right onto the forest track. Carry on, initially on relatively flat ground then downhill, and continue along the tarmac to the next junction, at the end of the Chemin des Vernets.
(12) Continue to the left and you will soon reach the Source du Jabron campsite (S/E).
