The starting point is Orpierre. Take the D30 from Eygians between Laragne and Serres to reach it. Once in the village, head towards the campsite and park between the mini-market and the swimming pool.
(S/E) Continue south on the road and cross the campsite, continuing straight ahead on theGR® 946.
(1) After about fifteen minutes' walk from the start, turn right, heading west, at the crossroads (left is the way back). Continue and pass the ruins of the Paturle farm.
(2) Just above the ruins of the Paturle farm, at a fork, turn right, heading southwest, staying on theGR® (white and red markings). You will come to a forest path, which you follow for a few dozen metres.
Turn left onto a steep path that leads to a wider track where you leave the GR®.
(3) Follow this track on the left, heading north-east, marked in yellow.
(4) At the orientation table (a beautiful viewpoint above Orpierre), turn right to reach the summit of Rocher de St-Michel in a few minutes.
(5) Enjoy the 360° view at the summit and descend to the orientation table.
(4) Head west down a steep slope (still marked in yellow) and turn right at the first intersection.
(6) Follow the signs for "Orpierre via the Plaine des Bessons".
The path leads to a wide forest track that takes you back to the junction mentioned above, just above the campsite.
