Departure from the free car park at the Museum of Prehistory in Quinson, Allée des Près du Verdon.
(S/E) Leave the car park and continue straight ahead towards the Verdon. When you reach a track alongside the Verdon, turn right and continue straight ahead towards the bridge.
(1) Turn left to cross the Verdon. After the bridge, take the path immediately downhill to the left, reach a car park and follow the track uphill to the right which joins a small road, Chemin du Pont.
(2) Take this road on the left. At the next X-shaped junction, continue straight ahead. Pass a multi-path junction and continue straight ahead on the track, Chemin de Saint-Maime, to the top of the cliff at an altitude of 483 metres.
(3) Continue slightly to the left, pass the picnic area, then on the left side of the building and continue straight ahead to the X-shaped crossroads at an elevation of 511 metres.
(4) Turn left, then 20 metres later take a small path downhill to the right. At the Y-junction, turn left, pass through the bottom of the Sousville valley and join a track.
(5) At the Jaubin 265 signpost, turn left towards the viewpoint. At the T-junction, turn left. At the top of the hill, turn onto a small path on the left to reach a viewpoint, return to the track and turn left until you reach the Route de Saint-Laurent.
(6) Immediately take the track on the left. After 50 m, turn onto a small path descending to the right towards Lac de Gorge Longue. Join a track.
(7) Turn right along the Verdon until you reach the nearby fork.
(8) At the junction with a small path, turn left onto the small path but just before you do, head towards the Verdon for 10 metres for a view of the Verdon and the bridge, then return to the small path to join the Route de Saint-Laurent, passing through the bottom of the Vallon de Grignolets.
(9) At the D471, turn left and cross over the Verdon. After the bridge, turn left onto a small path towards the Notre-Dame Chapel. At the junction at an elevation of 410 metres, continue straight ahead to the end of the small path, opposite the pine forest at a place called Notre-Dame.
(10) You can also take an 800-metre round trip to reach the Notre Dame Chapel on the right.
Take the track on the left and 50 m further on, at the end of the woods, follow a track on the right which turns into a small path and continue straight ahead to join another track.
(11) Turn left, join a sandy track and turn left. At the Y-junction further on, turn left and you will come to a junction with a cistern.
(12) Turn left at the junction of two grass tracks, continue left and arrive at a junction with a small path marked "grotte" (cave). Continue straight ahead on the grass track. I do not recommend this path, which leads directly to the cave, as I find it too dangerous. Arrive at a T-junction of two small paths.
(13) Turn right and, at the next junction, turn left to join a track in front of a metal electricity pole. Take the track on the right which joins a large track.
(14) Turn left until you reach a Y-junction of two tracks.
::15:
Turn left, reach a small clearing and continue straight ahead on the yellow marked path to descend towards the Baume Bonne cave.
(16) Retrace your steps, descend a few metres and turn right to reach the Verdon and see the Quinson dam. Retrace your steps to return to the start of the small path, taking care to turn left at the bend.
(15) Go back up to the main track and turn left. Take an old track on the left for 100 m to see the dam and return to the track above to turn left towards the antenna for the viewpoint over the Quinson valley.
(17) Retrace your steps to return to the previous fork.
(15) Continue straight ahead on the track and go back up to another fork, which you also passed earlier.
(14) Continue straight ahead on the track until you reach a small path on the left (signpost).
(18) Turn left towards Quinson. At the T-junction at the start of the series of information signs, turn right, walk alongside the signs and follow the yellow markings to descend the very steep slope towards the valley. Join the dam road.
(19) Turn left, then right to reach the car park of the Museum of Prehistory (S/E) further on.
