To reach Le Groseau, take the D974 south-east of Malaucène. Park in the car park before the restaurant.
White and redGR®4markings
(S/E) From the car park, turn left onto the D974 and look for the Notre-Dame du Groseau chapel 300 metres further down on the left. This chapel is not often open, but you can enter the small park.
(1) Return to the road and continue left until you reach the crossroads.
White and redGR®91markings + yellow markings
(2) Turn left towards Les Aréniers, following the small tarmac road. At the next crossroads, marked by a very large Italian poplar tree, turn left to enter the disused site of the Papeteries de Malaucène. 50m further on, a wooden cross marks the start of the Way of the Cross trail. Turn right and follow this path, which joins a track further on. Turn right onto this track, which runs alongside the D974 below. At a fork, take the path on the left, which climbs back up to the road.
(3) Cross the road with caution, ignore the first path on the left and take the next one, which climbs up the hill via steps.
Continue along the path through the box trees and pines. Higher up, a few switchbacks allow you to pass through a rocky area. On a flat section, the path turns left and offers views of Malaucène. A little further on, at a cross, the path turns right towards the east and reaches a fork.
Leave the path that branches off to the left and continue on the path to the right, which leads to the Chapelle de Piaud.
(4) Leave the paths to the left of the chapel and take the path on the right, which passes a bench and joins the D974 300 metres further down.
Cross the road with caution as the path comes out onto a bend. Opposite, you will come to a car park with an information panel about the plants of the Ventoux.
Go to the Roucas di Pouarès signpost on the left of the esplanade. Turn left towards Combe Obscure along a stony path that descends steeply to a crossroads.
Yellow + orange signposting
(5) Turn left, following the sign for Bramafan (Brame-Fam on the map). Walk along the Combe du Grand Barbeirol until you reach a Y-junction at the end of the valley.
(6) Follow the path on the left and, when you reach the large cedar trees, turn right into the Combe de Brame-Fam. About 350m further on, at a fork, turn left onto the path that joins the D974.
Cross the road carefully to find the Bramafan signpost. Turn right onto the path parallel to the road towards Le Sueil.
White and redGR®4signposts + yellow signposts
(7) At the Sueil crossroads, continue straight ahead on the track towards the Chapelle Saint-Sidoine. 10m further on, leave the path on the right that climbs uphill and continue straight ahead.
after 400m, leave the track and turn left onto a path, following the markings. When this path starts to turn left, leave it and take the path that branches off to the right into the pine trees; it joins the track shortly afterwards.
Turn left onto the track and continue for 10 metres until you see signs indicating a path. Turn right onto the path and follow the signs, which will take you back to the track.
Continue right and follow the track until it comes out onto a small esplanade. Leave the path on the left marked with a sign for Chapelle Saint-Sidoine and a red and white cross, then continue for 50 m on the track.
Leave the track and turn left onto a path that enters the forest. After 50 metres, ignore a path opposite and continue left, following the signs (not marked on the map). At the next fork, the path turns left and descends towards the Chapelle Saint-Sidoine.
(8) Follow the same route back to the Le Sueil crossroads.
White and redGR®4markings + yellow markings + orange markings
(7) Turn right towards Comentige. After 100 m, leave the path on the left (not shown on the map) and follow the one on the right through the pine trees to the Comentige signpost.
(9) Continue straight ahead towards La Baume. 50m further on, at a fork (not marked on the map), turn left to begin the descent into the Combe de Comentige. The path, which is very stony and steep at first, ends much more pleasantly and joins a wider path.
Follow it opposite between the cherry trees to reach the La Baume crossroads.
White and redGR®4markings
(10) Turn left and head back up towards Le Groseau. On the flat section, at the crossroads, turn left and then immediately left again, following a track that descends.
Ignore all the paths on either side and stay on the main track. Pass the ruins of a plaster factory and you will come out onto the D974 opposite the restaurant.
Turn left to see the source of the Groseau, then retrace your steps towards the restaurant and the car park (S/E).
