Park along the access road to the Pélissier National Forest, just after the signs. There is a car park a little further down, where you can also park, but this will add a little distance and elevation to the hike.
(S/E) Walk back up the departmental road to the Col de la Mort d'Imbert. After about a hundred metres, you will see the start of the hike on your right. There is a sign for the Pétavigne walk. You can't miss it. You will soon arrive at the Carrefour des Acidulés.
(1) At a three-way junction, you will find the start of the circular route. I strongly advise you to do the hike in the direction indicated (you can do the route in reverse, but then you will start with a very significant climb). It is therefore better to start on the right, i.e. follow the track that heads west-southwest.
Take the opportunity to admire the incredible diversity of flora and fauna you will encounter along the way. There is an alternation of deciduous and coniferous trees throughout the route. And there are many signs of foxes. I caught a glimpse of one with its cubs.
Stay on the widest path (keep straight ahead on a fire access road) until you reach a crossroads where, on the right, you will see a fire water tank and, on the left, the clearly visible yellow signs for the Luberon ridge trails.
(2) Follow the small path that goes down to the left (follow the signs). After a short while, you will come across a nice cave on your left that is worth visiting. Feel free to stop, as there is no danger.
(3) Continue along the path, which climbs slightly.
(4) At the three-way junction, you have two options:
- You can turn left and go back down the path you took earlier, or turn right.
- You can turn right and continue climbing to the peaks: this is the option shown on the map and described below.
Turn right and continue straight ahead. Enjoy the superb views from the ridges, with Mont Ventoux on your left and breathtaking views of Manosque and the Durance valley on the other side.
As you descend, you will come to another fire track that leads down to the Carrefour des Acidulés. The descent to the crossroads is very steep.
(1) Turn right to return to the pass, then left to return to the starting point (S/E).
