The start is 4 km from Murs. From Murs, take the D102A towards Joucas. About 500 m from the village, turn right onto a small road (signposted ‘Le Mourre Blanc’ hike) and park at the very end (start of the GR® de Pays Rouge et Jaune trail heading east).
(S/E) Follow the pleasant path for 500 m to the junction (signposted ‘La basse Auvières’).
(1) Turn left (GR® de Pays) and continue for 800 m to reach Baume Brune.
(2) Then head down to the left (south-west) along a winding path to join the Bois d'Audibert track, which you follow for barely 200 m before continuing along the Red and Yellow GR® de Pays, passing through pine woods, olive groves and meadows before reaching the very pretty hamlet of Les Grailles.
(3) Then begin the ascent into the gorges heading due north for about 400 m, continue along the Red and Yellow trail which climbs along a ledge, then turn right at the signpost onto the path that zigzags down to the bottom of the gorges; 300 m further on, you’ll reach the Moulin Cabrier (ruins), which you must go round to the left. The path then follows the superb béal (water channel), carved into the rock.
You then reach a ladder with ten rungs leading up to the Pas de Marie-Hélène, which overlooks the gorge. You will need to use your hands from time to time. Take care on the rocks as they are slippery. Make your way through the gorge, crossing over and following the balcony paths to reach a narrow pass which you must descend, using the steps and cables provided, to return to the gorge floor.
The trail markers lead you back up through the sometimes lush vegetation and emerge into a magnificent, wide canyon (or ravine).
(4) Continue through the wild gorges at this point to reach the ruins of the Moulin Jean de Mare.
(5) Take the path that branches off to the left of the mill to reach the junction of the paths at the signpost, Jean de Marre. Continue northwards to the crossing with the river (about 250 m), which you cross to the right (follow the yellow markings).
(6) Continue along the path to the junction (Lauzière) with the track.
(7) Take the track on the right for about 500 m, then turn left (signposted Les Trois Évêchés).
(8) Follow this path down to the right, through holm oaks, to the boundary marker (Les Auvières).
(9) Continue straight ahead towards the east (Joucas) to reach the La Basse Auvières marker (already passed on the way there).
(1) Continue straight ahead to return to the vehicle left at the start (S/E).


However, I must warn you that the difficulty level does not deserve to be classified as "medium"! The other hikes through the Gorges de la Véroncle, which you can easily find on Visorando, are marked as difficult, and in my opinion, this is much more accurate.
