Sentier Marcel Estruch and Grotte aux Œufs via Saint-Pilon

A beautiful, challenging hike that combines many of the features of Sainte-Baume: undergrowth, ledges, chain passages, a visit to a cave, ridges, etc.

"A protected species, the peregrine falcon, nests on the Béguines cliff and may be disturbed. Avoid using this trail between February and June to ensure its protection."

Description of the walk

Park at the Hôtellerie de la Sainte-Baume car park.

(S/E) Head to the far end of the car park to the east to join the path leading towards the Trois Chênes car park.

(1) Once you reach Les Trois Chênes, look for the yellow markings and the path. You will need to follow these yellow markings for a large part 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 on, first heading south-west then north-east, until you come back onto 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 branching off to the right and head uphill 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 the Pas de l'Aï. Look out 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 is located 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 path is divided into two sections: thefirst is relatively easy and presents no particular difficulty; the second includes a few technical sections: no climbing (one of them is graded 3b), pendulum chains (not necessarily required), and sections with horizontal or vertical chains. As the markings are regular, if you can no longer see them, retrace your steps.

(6) You’ll come out onto the path leading to the Col du Saint-Pilon (GR®®9, red and white 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 the Pas de la Cabre.

(9) At this point, join the Brown trail on the right. This will take you back down.

(10) When you reach this junction, take the Green trail branching off to the left. Make sure you stay on the Green trail marked with a single solid line and do not take the Green trail marked with a dotted line which appears a little further on. You will arrive at the Grotte aux Œufs.

(11) Continue along the path until you reach a junction.

(12) Turn left to rejoin 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).

Notes

"A protected species nests on the Béguines cliff and may be disturbed. Avoid using this path between February and June to ensure its protection. More information via this link http://sainte-baume.n2000.fr/natura-2000..."

Regarding the elevation gain on this hike, despite using several GPS devices (ranging from 400 to 1,800 m), this figure is only very approximate due to the steepness of the Marcel Estruch Trail. It is reasonable to expect around 700 m.
The same applies to the total distance: expect between 17 and 18 km.

As with any fairly long hike, bring: water, food, a windbreaker, a change of clothes, and protection from the cold (part of the route is in the shade) and the sun.

It is not advisable to do this circular route in wet weather, as sections can become quite slippery. The same applies in the event of strong northerly winds on the sections with chains.
Those familiar with the climb to the Col du Saint-Pilon will note that the exit from the Sentier Estruch is not signposted on theGR®®9. It is best to follow the route indicated in this guide (to avoid any crossings).

Worth a visit

It is possible to modify the route to shorten the hike at several points.
On the way up, on the Sentier Merveilleux, a Black trail joins the Sentier Marcel Estruch, cutting across a good portion of thefirst half of the latter.
At point (6), it is possible to head back down via theGR®®9and thus visit the Grotte de Marie-Madeleine.

Always be cautious and plan ahead when you're outdoors. Visorando and the author of this route cannot be held responsible for any accidents occurring on this route.

A route without too many technical difficulties for experienced hikers, although there are some dizzying sections. You need to remain very attentive and vigilant. However, it’s not worth doing the circular route via the ridges
The trail is already quite demanding, and the return via the descent to the car parks is sufficient.

A very beautiful hike with exceptional views, but always in the shade in autumn.
Well-equipped passages with drops, but a slightly dangerous climbing passage that is not easy for smaller people.
The yellow markings are somewhat random, and we lost them 500 metres before the Chapelle des Parisiens.
In conclusion, this is a hike for hikers who are not afraid of heights.

Parish specific to Brittany, the aerial route is quite short, only a vertical section can be limiting.

The view is magnificent.

The yellow route used for the aerial route can sometimes be difficult to follow

Completed at the end of September
The route is well marked, but the yellow dots are sometimes a little faded, so you need to be careful as it is easy to take a wrong turn. You really must not be afraid of heights as the path is sometimes on the side of a cliff, very narrow and sometimes slippery. There are two or three climbing sections and chains.

A beautiful hike, with a balcony trail overlooking the valley.

There are a few narrow sections where you obviously need to be careful and have sure footing.

Strongly not recommended for those who are not sure-footed or suffer from vertigo.

Thank you for sharing this beautiful route.

I confirm the description: difficult trail, best not to walk it alone (on the Marcel Estruch section). I couldn't find the shortcut via the "Sentier Noir" (see "On the way there, on the Sentier Merveilleux, a black trail joins the Sentier Marcel Estruch, cutting off a large part of the first half of the latter"). It is advisable to wear trousers and bring water and some food.

an IBP score of 69 would indicate a "slightly difficult" level of difficulty for a person of average physical fitness.
However, this does not take into account the chain passages or the two or three unrated climbing passages.
The purpose of increasing the rating is to make it clear to hikers that this route is not flat and requires a steady footing

The final classification of difficulty is highly subjective and depends largely on the site rather than the author.
It should not be forgotten that perception is highly relative.
As soon as there is a notion of passages with empty space, the rating skyrockets

Beautiful views, but it was pretty easy!

We were expecting something much more difficult! We did it in less than five hours with my nine-year-old son.

In our opinion, it would be better to classify it as difficult (or perhaps very difficult). The extremely difficult classification is really unjustified. We've done difficult ones that were more or less the same level.

Hike completed on 30/10.
Magnificent, and with "gas", indeed it's not for everyone.
My advice is to follow the yellow markers, which are sometimes hard to see, but if you look carefully, you'll find them ;-). We cut this hike short at point 6 because we lost a lot of time on the M. Estruch trail.
I can confirm that the safety points on the chains have been repaired.
Thanks Cyril for sharing this information, without which we would certainly never have done this hike.

A very beautiful, challenging hike with stunning scenery. With a bit of luck, you might spot some of the local wildlife. These same animals disturb the tracks by digging up the ground, making the trail disappear in places. The yellow markings are sporadic in places. A GPS device is useful. For me, the most difficult part was climbing certain rocky sections. Not for everyone. The chains have all been serviced and are in very good condition. The sections with chains are therefore safe. I was the only person on the trail on Saturday.

Superb hike! Not a soul in sight... except for some chamois!
five hours for an experienced hiker and climber. I equipped myself with a harness and a via ferrata kit for the few difficult sections (not necessary but reassuring...).
This hike is not recommended in windy conditions or after rain.
I set off alone and didn't see anyone else.

Although we set off early, it was quite hot. There were frequent yellow markings, so we quickly started to wonder where we were as soon as we couldn't see any more. There was abundant vegetation and quite a few low branches. There were wild goats on the path, one of which followed us to lick our skin, no doubt for the salt. Superb views, reasonably difficult if you stay alert. A beautiful hike.

It's difficult to get a reliable elevation reading on the side of a cliff
The three GPS devices we used gave unrealistic readings (2,000 metres for the most enthusiastic) in 2017.
