Description of the walk

The village of Longes, located in the Pilat mountains, can be reached from the Gier valley by taking the D502 via the village of Trève, or from the Rhône valley from Condrieu towards Rive-de-Gier. In the village of Longes, park in the Place de Verdun car park. The hike starts from this point.

(S/E) Leave the car park (leaving the church behind you) and take the Grande Rue on the right, downhill.
Ignore Rue du Dauphiné on your right and take the next left (Rue de Suzieu). The tarmac road ends and gives way to a dirt track. Continue straight ahead on this track.
Ignore a path on the left and continue straight ahead downhill.

(1) At the bottom of the valley, you will reach a stream and a footbridge over the water (Passerelle de la Broie). Cross the stream and continue uphill on the other side. Continue straight ahead, ignoring a path on the left. Cross a crossroads, continuing straight ahead. You will reach the hamlet of La Balasserie and arrive at a road (Chemin de Fontblanche).

(2) Turn left. Continue straight ahead on this road uphill. The road ends and becomes a dirt track. Continue straight ahead on this track. Ignore a path on the right, then another on the left, and continue straight ahead until you reach a road (D625E) where there is a hiking signpost (Croix du Trève).

(3) Take this road on the right. Continue for only twenty metres, then leave it for a small road on the left (Route de Sainte-Croix). About twenty metres further on, you will come to a fork in the road; take the path on the right here. Then ignore a path on the right and continue straight ahead.
Cross the hamlet of Marlin, turning right at each intersection. Once you have crossed the hamlet, ignore a turn-off on the right and then a turn-off on the left to reach an intersection with a hiking signpost (Marlin).

(4) This signpost points towards the Roches de Marlin. Turn left towards them. Along the path, a few metres before reaching an information panel about the Roches de Marlin site, turn left to reach the Croix de Marlin.

(5) Once you have admired the view from this point, retrace your steps to return to the original path at the information panel.

(6) At the crossroads, where there is a signpost (Les Roches de Marlin), continue straight ahead for about 50 metres to reach the end of the Roches de Marlin site.

(7) Then retrace your steps back to the crossroads.

(6) Turn right downhill towards Sainte-Croix-en-Jarez.

(8) At the crossroads, at the hiking signpost (Champ du Peu), turn right and continue along this path. The dirt track then becomes a tarmac road (Chemin de Vienne) and leads to a crossroads.

(9) At this crossroads, there is a hiking signpost (Jurieux). Turn right and then, a few metres further on, turn left (Route de Jurieux). In the hamlet of Jurieux, take a short detour to the right to admire the old chapel, then continue down the same road.

(10) Cross the hamlet of Thesay and continue along the road until you reach a larger road. Cross this road carefully and turn left onto the small path on the other side, opposite the corner of the cemetery wall, which descends towards the charterhouse. Turn left and follow the path that runs alongside the buildings for about 50 metres after crossing a small bridge (Chemin des Viviers). At the first crossroads, turn right towards a tunnel-like passage that leads to the middle of one of the monastery's courtyards (Cour des Pères). Cross the courtyard, keeping to the left.

(11) Take the Passage des Voûtes, which leads to the second courtyard of the monastery (Cour des Frères). Continue towards the main gate, then exit the monastery. Cross the road and turn left opposite, then, a few metres further on, turn right onto the Route de la Conty, which leads uphill.

(12) You will reach a crossroads where, on the right, a street sign indicates Route de la Conty. Cross the hamlet of La Conty. When you reach an intersection at the end of the hamlet, turn right and follow the road around a bend. At the end of the bend, turn left (inside the bend) onto a dirt track. Continue straight ahead until you reach a small stream.

(13) Ford the stream or cross the footbridge, and continue uphill on the other side.

(14) When you reach a crossroads with a hiking signpost (without a name), continue straight ahead. You will reach a road and a crossroads on the left about ten metres further on, where you will see the Croix du Trève.

(15) Cross the crossroads and take the road opposite that branches off to the right. After about 60 metres, leave the road and take a dirt track on the right, uphill. Continue straight ahead on this path until you reach a crossroads with the Croix de la Garde.

(16) Turn left and continue straight ahead until you reach the hamlet of La Garde.

(17) Cross the hamlet, continuing straight ahead at the intersection. You will then come to a fork in the road; take the left fork. You will come to another fork in the road; keep to the right. Continue along this path until you reach a road.

(18) Take the road on the right and continue straight ahead. The road will become a dirt track. Continue along this track until you reach the first houses in the village of Longes. Continue straight ahead, ignoring a road branching off to the right. When you reach an intersection (Rue du Château), turn left. Continue straight ahead at the next crossroads. Join the main road that crosses the village and turn left downhill. Continue until you reach Place de Verdun (S/E).

A very pleasant walk with a little bonus: a delicious crème brûlée with Chartreuse liqueur at the Auberge Cartusienne, opposite the Chartreuse de Sainte Croix en Jarez.

A very pleasant hike with very little road walking and beautiful panoramic views. Option to break up the hike with a stop at a restaurant in Ste Croix en Jarez.

Error in the description between points 2 and 3: the paved Fontblanche road continues after the dirt road junction. The description does not mention this continuation

Hello everyone,
There were six of us scouting this hike for our walking club, "Les Tamalous", which we are planning to do on 11 May 2025.
It's a very beautiful hike, but not easy in the ups and downs in case of rain...
We set off from Longes as recommended, but for our hike on the 11th, we plan to park in the car park near the containers at the Trève crossroads, which will allow us to do a circular hike via Longes in the morning and not have to carry our picnic with us. We will then have our picnic and, for those who wish, the second circular loop and meet up in Ste Croix en Jarez with those who came by car and visit this magnificent Chartreuse.
A very pleasant hike, but classified as moderate and covering 16 km.
I can only recommend it because it combines a pleasant hike with cultural attractions (Roches de Marlin, Chapelle de Jurieux, Chartreuse de Ste Croix, etc.).
No problems with the route description.
I imagine it gets quite busy when the weather is good, but mainly in the St Croix and Roches de Marlin areas.
Thank you for describing such a beautiful walk in the pleasant Pilat massif.
Happy hiking, everyone.
Dominique

Hike under grey skies with a few showers along the way, beautiful views of the Gier Valley, Sainte Croix en Jarez is a very pretty village that is definitely worth a visit, and take the opportunity to stop for a break if the bars and restaurants are open. A hike that is not too difficult, best done in cooler seasons as the route is not very shaded.
Thanks to the author.

Superb route with beautiful views throughout the walk. Lots of paths and few roads. Walked on a fine morning in September. We did it in less than 4 hours with a break of about 30 minutes. I highly recommend this hike.
