Park in the car park near the Museum of Prehistory on the D9 road.
Yellow signposts.
(S/E) From the car park, head north on the D9 road, pass the cooperative winery and turn right when the yellow sign indicates.
Stay on this small road, ignoring the side paths. Further on, the road will turn into a track before joining a mini tarmac track.
Follow this track downhill to an intersection.
(1) Turn right to reach a new intersection of tracks at a three-way junction.
(2) Continue straight ahead. A few dozen metres later, you will cross some undergrowth which will lead you to the D9 after a steep and fast descent.
(3) Take the D9 on the left, then leave it immediately by turning right to reach the edge of the Verdouble. You will come to a trail intersection.
(4) Cross the Verdouble and stay on the main path, which winds its way through the vineyards. Ignore all side paths and stay on the main route, which will take you to Avenue du Verdouble.
(5) Stay on this avenue until you reach an intersection with a ford.
(6) Cross the Verdouble and continue along Allée Jacques Respaud until you reach Rue Anatole France. Turn right, then left onto Rue Louis Torcatis before rejoining Avenue Jean Jaurès (or Route D9) on the left. Continue along the road until you reach the car park (S/E).
