Description of the walk

The hike starts in the shaded car park at the Curis fountain. This car park is located just after the traffic lights on the road to Saint-Germain-au-Mont-d'Or.

(S/E) At the traffic lights, before continuing right towards Poleymieux, take a few moments to see an old wash house located a few dozen metres on the left towards Neuville-sur-Saône. Retrace your steps.
Follow the road towards Poleymieux for 50 metres and take the small staircase on the left. At the top of the stairs, turn right into the street and head towards the large gate marking the entrance to the castle grounds.

Go through the gate and follow the path that runs along the left side of the park. At the first crossroads, turn left towards "Grand Platane".
After a right-hand bend, an open space with a bench offers a beautiful view of the castle.
At the next crossroads, "Grand Platane", turn left towards "Les Escaliers".
At the large staircase, follow the signs for "Porte du Pinay".

(1) Go through the gate and take the fairly wide unmarked path opposite the gate, which narrows quite quickly.
After leaving the small paths that branch off to the left and go up into the forest, you will come to a crossroads just after a pile of earth on the path.
Turn left onto the path to reach the "Croix Vitaize", which can be seen at the end of the straight road.

(2) Cross the road and head towards "Chargeri" by taking the path that starts with a few steps. It is located to the left of the forest road.
After passing the entrance to a field, continue straight ahead, ignoring the path that branches off to the right.
The path will join the forest road, which you should follow to the left to reach the "Chargeri" signpost.
At "Chargeri", continue towards "La Crête" on the rocky path.

(3) Turn slightly left to reach the signpost marked "Dent du Loup", which can be seen at the end of the meadow. This meadow is full of flowers in May and June.
When you reach "La Dent du Loup", turn right to reach Mont Thou.
Note: At the "La Crête" signpost, you can go directly to Mont Thou.

(4) At Mont Thou, enjoy the beautiful view of the Saône valley and the Ain plain, and further afield if the weather permits. Take the time to walk along the rocky path.
To continue, go back through the gate and take the path that descends furthest to the left.

(5) When you reach the edge of the woods, take the path on the left that leads into the woods. At the crossroads, continue downhill, turning left.
Continue straight ahead at a crossroads, going downhill, until you reach another larger crossroads.

(6) Turn left. After about 20 metres, leave the small path that branches off to the left.
After 200 metres, the path crosses a meadow and runs alongside a cultivated field before joining a road. At this crossing, the path is very narrow and it is recommended that if there are several hikers, you walk in single file so as not to trample the crops.
Turn right onto the road and follow it for 600 metres, then in the middle of a short straight section, after a sharp left-hand bend, take the path on the left.
Caution: In the left-hand bend of the road, the shoulder is practically non-existent and it is safer to stay on the right-hand side of the road.

(7) At the start of the path, a barrier blocks access to vehicles but leaves a pedestrian passage.
After 300 metres and about 20 metres before a right-angle bend, take the fairly inconspicuous path that starts on a large flat stone next to an oak tree with a double trunk. (See photo "Start of path").
This path winds between fir trees. After a few zigzags, the path crosses a large, partially collapsed stone wall (see photo "Old wall").
The path descends and joins the edge of a meadow, then crosses it to reach a path at the edge of the woods.
Turn left onto the path and follow it for about 250 metres.

(8) In a left-hand bend, take the path on the right that leads into the woods. This path joins a small road which you must cross to take the path that continues straight ahead on the embankment.
After 200 metres, the path joins a track. Turn right onto the track, then turn left after 50 metres to follow the path that climbs into the forest. At the first crossroads, which is muddy when wet, turn left to join the Route du Mont Verdun.

(9) Cross the crossroads and continue along the road opposite, towards Limonest, for about 50 metres. Take the time to look at the landscape before taking the path that branches off to the right on the hillside and starts with a small concrete platform.
This path goes around Mont Verdun, which is not accessible.
Join a road and follow it to the right until you reach a crossroads about 300 metres away.

(10) Shortly after the crossroads, take a path on the left opposite two tennis courts (Croix du Mont Verdun). When you reach a small road, follow the sign for "Mont Rouge" and follow the direction for "Lavoir des cendres". To do this, take the small path that branches off to the left just before the gate to the Py quarry (in operation). Follow this path until you reach a road. Signpost "Lavoir des Cendres".

(11) Follow the road to the right until you reach a junction with a concrete road.
At the crossroads, take the concrete road on the left to see the wash house located about 50 metres away.
To continue, return to the crossroads and follow the road to the left until you reach a junction with a path. Signpost "Le Bottet"
Turn sharply onto the path towards the "Moulin à Vent" (windmill). When the weather is clear, you can see the Alps and Mont Blanc.
After the ruins of the mill, where there are picnic tables, take the path on the left that climbs towards the Croix Rampau.

(12) On the north side of the Croix Rampau, a paragliding launch site offers unobstructed views of the Saône valley and the Beaujolais region.
Continue along the path that disappears into the vegetation opposite the arrival path.
The path then descends through a wood before joining a track. Turn right onto the track and after about 20 metres take the path on the left which descends into the forest towards Curis.

(13) The trail then runs alongside and then below a vineyard. Leave the trail that branches off to the right and continue on the trail that enters the forest again to join a larger path.
Turn right onto the path and follow it for about 200 metres until you reach a small, fairly inconspicuous path.

(14) Turn onto the small path that branches off to the right of the road and enters the woods. Follow this path downhill, crossing a fairly steep section before reaching the "Chemin du Chêne".
Turn left onto Chemin du Chêne and follow it downhill to the road.
Continue left on the road, follow it for about 100 metres and take the small street on the left to reach the car park (S/E).

Notes

This hike passes through several areas where the grass is very tall in May and June. The grass hides many small animals, including ticks. Remember to keep an eye on your legs and arms if they are bare.
The Visorando mobile app is a plus, as some of the trails are quite "discreet" and unmarked.

Description to be updated if necessary: parking is prohibited at the Fontaine car park. The Vallon car park is nearby and can be used instead.
We encountered a minor difficulty on section (9), the Mont Verdun detour. An unmarked fork in the path led us into the boxwood trees. Returning to the fork, we saw the concrete marker. Take the path on the left, which descends slightly, rather than the one on the right.
The last change we noticed compared to the description is at the air base tennis courts, which are being replaced by new buildings.
The entire route is very pleasant because it is shaded, and the ground is dry, so it was relatively easy.
Thank you

Hello and thank you for this map.
For your information, parking at La Fontaine is now prohibited and the tennis courts mentioned in the trail description no longer exist. Construction is currently underway on this site.
A very beautiful route, completed today, the shade was much appreciated.

A very pleasant route that constantly seeks to avoid the beaten track.
It was sometimes difficult to follow you as the trails you suggested were so unusual. But by sticking to the tracks, it was possible and really worth it.
Thank you for this great hike.

Very interesting hike. Beautiful views. The trail marked 14 isn't that difficult to find: it's opposite another trail that branches off to the left and is very visible. From there, the descent is tricky, especially when it's wet.
I would definitely do this hike again.

This hike can be done in hot weather as it is very shaded throughout. One small drawback is that the path down to Curis is difficult to find as it is not very well marked.
Otherwise, an excellent hike

Superb hike on pretty paths and trails. Several steep climbs and descents, especially the last one, which is quite slippery due to rain. You need to watch your step as it is very narrow
Nice view of Mount Thou when the sky isn't foggy
I used the app and the description without any problems.

Thanks to the author for this beautiful hike

Thank you to the author of this hike, which is truly superb. 99% of the trail is dirt.
Beautiful views. The last descent in rainy weather is very slippery and requires caution.
PS: I use the app to guide me. Without it, it's easy to get lost.

Superb hike with magnificent views of Lyon and the surrounding valleys. A few steep sections on the way up to Mont Verdun and on the descent at the end. But nothing difficult for a good walker.
Lots of people approaching and on the mountains/viewpoints, as it was a beautiful day during the long Ascension weekend, a popular place for family outings. We didn't see anyone else on the other parts of the hike.
Thank you to the designer of this beautiful hike

Very beautiful route, unfortunately there are many mountain bikers who ride at high speed and do not warn of their arrival (it seems they do not have bells on their bikes, which is mandatory) - the last section is dangerous, with a very steep, uneven and narrow path (not to be attempted in muddy conditions or by people who suffer from vertigo like me). As for the elevation gain, we used a GPS and it was quite substantial: 600 m rather than the 300 m indicated in the description

As always, I download the GPX file to follow the route on my GPS, which is so much more convenient.
The ride is really nice, with cool air in the forest and several beautiful views of different slopes, Lyon/Dombes/Bugey on the Thou side, the Poleymieux valley, and the Beaujolais region as you reach Mont Verdun... and the Château de Curis at the start.
As mentioned previously, it's better to descend via the road to the hairpin bend between 7 and 8, otherwise you'll have to tackle a short climb and a steep descent, which are unnecessary and on private land. Admittedly, this adds 200 m to the route (keep well to the left, as these bends are popular with Porsche drivers).
Don't hesitate to push on to the Fort de Verdun to reach 600 m and enjoy a lovely view.
You'll also pass the remains of the mill where Ampère used to woo his sweetheart...
