Start from the Carrières de Lumières car park at the exit of Les Baux-de-Provence.
No signposts
(S/E) Opposite the entrance to the quarries, turn left onto the tarmac road that descends.
At the crossroads, leave the Route de Maillane on your right and continue left onto the D78g. Pass some large boulders, leave a road on your left and continue downhill. Pass the town hall and turn left about 100 metres further on, just before the "Fin de zone à 30" road sign.
(1) Take this small paved road that climbs up and joins the D27. Cross the road, turn left and follow it for 50 metres. Take the stairs that climb up to the right, towards the village.
(2) Ignore the path on the right and continue climbing this paved slanting street. You will then enter the village of Les Baux-de-Provence, one of the most beautiful villages in France. Reach the car park, turn right onto the path with large steps, pass in front of the ruins carved into the rock and then go through the gate to enter the village.
When you reach the crossroads in front of the Ribaupierre workshop, turn right onto Rue de la Calade. Leave a narrow street on your left, then another one, to arrive at Place François de Hérain on your right.
On your left is the Yves Brayer Museum, then Saint-Vincent Church and the Chapelle des Pénitents. Walk around this square, which offers beautiful views of the surrounding area, and retrace your steps back to the museum.
Take the alley on the right and, at the end, continue right to reach the entrance to the Château des Baux-de-Provence (admission fee).
Turn around and go straight down Grand Rue. Pass a ruin that has been converted into a square named Prince Rainier III de Monaco, then continue to the right past a hotel. Pass the Tourist Office and leave the village.
Continue right on the road that climbs slightly, cross the car park, leave the entrance to another part of the car park on your right and continue straight ahead on the road that descends (exit sign). This road, which goes around the rock, joins the D27.
(3) Keep right and follow this road for 20 metres, then turn right towards the car park. Cross the car park and find a small path that leads into the heath opposite. Follow the signs for "Habitat des Trémaïé" and then "Stèles romaines des Trémaïé et Gaïé, Chapelle du Pélerinage".
Continue along the path that goes around the rock below the castle, offering beautiful views of the valley. Leave the path that branches off to the left just before the chapel.
(4) Admire the bas-relief of the Trémaïé family, which is 4 metres above ground level, just above the roof of the chapel. Leave the next path on the left and continue to the "Stèles de Gaïé" crossroads. Leave the small path that climbs up on the right and take the path on the left that leads to a rocky outcrop overlooking the valley.
Retrace your steps to find the path, then turn left. The path narrows and becomes a trail as it completes its detour around the rock. Pass in front of the Black Madonna and join the paved slanting street.
(2) Turn left onto the same path you took on the way there, rejoin the D27, follow it for a few metres, then cross it and take the small road on the right that descends to join the D78g.
(1) Cross the road and continue straight ahead. After the left-hand bend, take the path that climbs to the right and becomes a trail above the houses.
(5) 250m further on, look for a cairn and large stone slabs on the right. Turn right onto these slabs and follow a trail that goes a few metres to the left, then right again onto stepped slabs. Above, the trail turns right again towards a rocky outcrop.
Cross the rock via an easy passage equipped with bars, which leads to the plateau and a first crossroads. Continue right on the trail and reach a crossroads at the foot of a ruin (incorrect markings on the map, a non-existent trail is marked on the left and the one on the right is missing).
Continue left to go around these ruins, then left again onto the path. Stay on this main path, ignoring the other paths to the right and left, until you reach a junction with a concrete post.
(6) Continue right on the path that joins the D27. Turn left onto the D27, then right 100m further on a paved road marked with an AL110 sign.
Red and white signposting
Continue along this road, following theGR®6for 400 m, and when it starts to bend sharply to the left, turn right onto a track.
No signposts
Go through the gate and follow this track downhill to the bottom of the valley.
(7) Take the path that descends to the right into the Val d'Enfer, go through a gate, cross the car park and rejoin the road. Turn left and then left again at the next junction to climb back up to the car park (S/E).
