From Lambesc, on the D67a, you can park 100 m after the hamlet of La Bastide Blanche, on the right.
(S/E) Cross the road and take the path through the oak trees towards the west, alongside a small vineyard. You will come to a stone path that climbs north-west, running alongside a vineyard. Follow the hollow of a recently cleared valley, continuing north-west and ignoring all the paths that branch off to the left and right. Start climbing a slightly steeper slope and wind your way up to a paved road. Follow the road to the right up to a pass below a lookout tower.
(1) At the Col de la Vigie, take the path that climbs to the right and passes under a pylon. The path descends steeply, so take care of rolling stones, until you reach a crossroads. Cross the crossroads and take the track opposite heading north-west, signposted CC208. You will arrive near a first cistern.
(2) Continue along the track that stays on the ridge, ignoring all the tracks that branch off to the left and right.
Stay on this track until you reach a second cistern. Leave the track here and climb up the path on the right to reach the relay antenna.
(3) Continue along the path that descends towards the track. You will come to a double three-way junction; keep right, following the old signpost: Domaine Départemental de Caire Val. Turn right again towards the valley. Descend in regular zigzags and ignore the stony shortcuts and the left turn indicated by the Sylvacane signpost. You will arrive at a T-junction with another track. Take the blue sign on the right. You will then walk through a forest dotted with cypress trees. Go through a DFCI barrier and you will arrive at a crossroads: Hunting car park no. 2.
(4) Go straight ahead towards a double junction with two almost parallel paths. Take the left-hand path and ignore the two paths on the right. At the start of the left-hand bend, continue straight ahead along a path through the undergrowth for a few metres. Walk alongside a vineyard on the left and go around it, following the signs for Lambesc via Janet. Ignore the two paths on the right. Continue south-west along Chemin du Petit Janet until you reach a large red agricultural irrigation valve.
(5) Leave the track and turn right, heading west, onto the farm track. Go around a property with a large vegetable garden on your right. You will come to a small road which you take heading west. Pass to the right of a large white building, which is an oil mill. Continue along the road, which is the Chemin de Lambesc à la Tour de Janet, until you reach the hamlet of Janet, which you can see opposite.
(6) Cross the hamlet, following a large wall and then hedges. At the end of the hamlet, turn right at the sign for Chemin de la Bastide Blanche à Janet and continue west on the paved road, then the track, then the paved road again. Further on, take a road on the right, level with a property with a large rusty metal gate decorated with a mechanic's wrench. Follow the old signs for Chapelle Sainte-Anne, La Roque d'Anthéron. This road leads back to Bastide Blanche and the car park (S/E).
A magnificent walk with superb views from the ridges, but also bucolic scenery on the way down.
