Park in the Hôtellerie de la Sainte-Baume car park.
(S/E) Head towards the far end of the car park to the east to find the path leading to the Trois Chênes car park.
Once you arrive at Trois Chênes, look for the yellow markings and the trail. You will need to follow these yellow markings for most of the route.
(2) Leave the forest track and turn right onto the Sentier Merveilleux (still following the yellow markings), which you should follow straight ahead, first towards the south-west and then the north-east, until you come back to a forest track.
(3) Follow it to the right for 10 minutes to reach a clearing with a large dead tree.
(4) Take the path on the right and climb up to the third hairpin bend.
(5) At this point, the north face of Sainte-Baume will be in front of you and the path you are on will continue to your left towards Pas de l'Aï. Look for the yellow cross and a small path branching off to the right. This is the Marcel Estruch Path. A yellow marker bearing his name can be found on a small rock a few metres further on.
Follow this path, taking care not to lose sight of the yellow markings (either dotted lines or a solid line).
This trail is divided into two parts: thefirst is relatively easy and without any particular difficulty, while the second has a few technical sections: no climbing (one of them is rated 3b), pendulum chains (not necessarily necessary), and horizontal or vertical chain passages. The markings are regular, so if you can't see them anymore, retrace your steps.
(6) You will come out onto the path leading to the Col du Saint-Pilon (GR®®9, white and red markings). Turn left onto this path to reach the pass.
(7) On theGR®®9, turn right towards Saint-Pilon and its chapel.
(8) Continue along the ridge for about 1.4 km on theGR®®98to Pas de la Cabre.
(9) Take the brown trail on the right at this point. This will take you back down.
(10) When you reach this crossroads, take the Green trail on the left. Stay on the Green trail marked with a single line and do not take the Green trail marked with dots that you will see a little further on. You will arrive at the Grotte aux Œufs.
(11) Continue on your way until you reach a crossroads.
(12) Turn left to return to the forest track.
(13) Turn right, then less than 100 m further on, turn left and follow the track back to the original car park (S/E).
