Arriving from the south at Les Baux-de-Provence. Below the village perched on its rock, drive up the departmental road to the first hairpin bend. In the bend, turn left towards "Les Carrières de Lumières" and park for free as soon as possible (spaces are limited).
(S/E) Head north on the tarmac road for about 200 metres until you reach the sign marking the end of Les Baux-de-Provence. This is where the hike actually starts. Immediately after the town sign, turn right and follow the forest path heading north-east until you reach a crossroads with four paths/trails.
(1) Turn right and continue climbing. Ignore what looks like a path on the left and continue to a pass.
(2) Take the path ascending to the left, heading north, which follows the ridge, first as a road and then as a trail, to the viewpoint. Ignore the other paths to the right and opposite.
(3) Don't hesitate to climb up opposite the fire hydrant, higher than the forest path, following the ridge for a better view of the Alpilles.
(4) Once you reach the viewpoint, take the less steep descent on your left or set off on an adventure by descending on the right. Take the tarmac road on the right, heading west, until you reach a rock with a hole in it on your left, where you will have a beautiful view of the village.
Retrace your steps to the left-hand bend and take the forest path on the right.
(1) Turn right downhill to rejoin the tarmac road. Continue south and at the next crossroads, turn right down the D78G, which takes you 200 m further down to the "real" Val d'Enfer.
(6) A rock carved with the letters "Val d'Enfer" and the beginnings of a man-sized stone quarry welcome you at the entrance to this very narrow valley on your right. Climb up this north-west-facing valley; the path ends once again on the tarmac road. Descend via the same path.
(6) Turn right and follow the tarmac road south until you reach a single concrete path climbing up on your left.
(7) Follow this path up towards the village. Cross the main road at the pedestrian crossing and take the steps opposite, which lead to a small car park below the village. To the right of the car park, you will find a more "balanced" staircase. Take this staircase, which will lead you to the western entrance of the village.
Enter the village, follow Rue de la Paved Slanting Street northwards and exit via the north gate. Take the stairs on your left, heading north, rather than following the winding road, and take the road leading to the Lumières quarries, heading north, to return to your vehicle (S/E).
