Access: To get to the start of this hike, at the roundabout at the northern entrance to Sisteron, head towards La Baume, cross the Durance and turn right. Head towards Entrepierres then Vilhosc; continue on the D17 road to the Pont de la Reine Jeanne (end of the tarmac road). Continue on the track opposite for 3.7km (this is still the D17, but it is awaiting resurfacing) and leave your vehicles in a lay-by on the right after a steep climb.
(S/E) Retrace your steps for about 100 metres and take theGR®6on your right, climbing through the forest to Rocher de Sivayau, continuing on the GR®.
(1) You will see a renovated house on the right and reach a track with a wooden sign forGR®6Saint-Geniez. Once on the Saint-Geniez plateau, you will have a view of the Trainon mountains, the Jouère mountain and the Monges.
(2) Continue along this track until you reach the tarmac road, which you follow for 500 m to point 1103 on the map.
(3) Leave the road on the right and continue for 500 m until you reach the PR®.
(4) Turn right and walk for just under a kilometre to reach Chabert.
(5) Go behind the house and follow the track for 500 m. A path branches off to the right, keeping roughly level for a kilometre before descending towards the ruins of La Grange Neuve.
(6) A path branches off to the left. Follow it and, at the next fork, continue to the right.
(7) The path becomes very steep; this is the only part of the hike that requires a little caution (hiking poles are recommended). The slope levels out to join a forest track that passes through Abros and leads back to the cars (S/E).
