Park in the car park after the bridge, on the edge of the D40, 400m after Saint-Léger-du-Ventoux.
Yellow signposts
(S/E) From the car park, with your back to Mont Ventoux, take the small road on the left (north-west). After following the Toulourenc, the road comes to a footbridge on the right.
Red and white markings
(1) Continue left through a right-angle bend. After almost two kilometres, the road crosses the stream via a beautiful little stone bridge and turns left to pass in front of a car park.
(2) Turn right and look for the signpost 10 metres further on the left on the rock. Leave the road and take the path that climbs up the rocks at the start (at this point, the signpost on the map is no longer valid as it crosses private property).
At the first crossroads, turn left to descend towards the stream. When you reach the banks of the Toulourenc, take the path on the right which runs alongside it for a while.
About 600m further on at the fork (not shown on the map), turn right to begin the climb above the Gorges du Toulourenc. The trail climbs gradually for about two kilometres to reach the Gorges du Toulourenc signpost. Continue straight ahead for another 10m.
No signposts
(3) Leave the trail and take the track on the right that continues uphill. This track is not marked but is clearly visible on the ground and has no forks, contrary to what can be seen on the map. Join the D40, cross it with caution and head slightly to the right.
Yellow markings
(4) Continue for 50 m and turn right or left (both paths join up) then continue to the next junction. Leave the main path and take the path on the left. Further up, the path gives way to a trail cut through the vegetation but not clearly marked on the ground. When you reach a wide path, turn left and continue for 50 m.
(5) Leave the path and take the trail on the right, which will start to climb steeply. The markings are less visible, but the trail is very clear on the ground. After crossing the Vallat du Pas du Loup, the trail climbs steeply for the last 300 metres to reach the ridges.
(6) Continue to the right, but be careful of the cliffs, which are not secured. The trail alternates between open sections and sections in the forest, sometimes uphill, flat or downhill for about 4 km.
At times, you will be able to see the Ouvèze Valley and the Baronnies to the north and Mont Ventoux to the south.
Ignore any tracks that leave the main trail and are not marked.
At one point, the trail will veer slightly away from the ridges and appear to begin the descent, but it will rejoin them further on at a crossroads.
(7) Continue to the right and after 700 m you will come to a crossroads. Leave the path on your right at a water reservoir and shortly afterwards leave the path on your left.
(8) A few metres further on, the signposts indicate that you should turn left onto a very steep section that joins a path. When you reach this path, continue to the right for a little over 200 m, then turn left heading north.
When you reach a crossroads, turn right and continue a little further until you reach a crossroads with signposts.
Red and white signposts
(9) Turn sharply right to rejoin theGR®91and gradually begin the descent.
The path is not particularly difficult, but there are lots of stones, and it leads back to the starting point.
(10) When you reach the cemetery, go down the small tarmac road that joins the D40. Turn left onto the road and follow it for 200m to cross the bridge (be careful) and reach the car park (S/E).
