Description of the walk

When arriving in Messimy from the east, leave your car in the village, in one of the small car parks on Avenue des Alpes, for example.

Please note! This route is not signposted.

(S/E) Head west and turn left onto Rue Simon Rousseau, then right onto Rue du Vingtain. Pass the church and turn left onto Rue Froide. Immediately after, turn right onto Chemin du Chater. Continue straight on this path to leave the village. The path continues through the fields. Pass under a high-voltage power line and arrive at a crossroads.

(1) Continue straight ahead onto Chemin de Janton. Pass a few houses, then take the first path on the left.

(2) At the next junction, turn right, then at the crossroads 150m further on, continue straight ahead, leaving the hamlet of Jaricot on your left. Continue along this path, through the forest or along the edge of the forest, until you come out onto a road.

(3) Follow the road to the right. At the next crossroads, continue to the left.

(4) About 200m further on, take a path that branches off to the left and leads uphill. The path curves to the right and heads west. Continue through the undergrowth, ignoring a path branching off to the left, then reach a crossroads of several paths marked with a cross, near a road. Continue straight on to join the road.

(5) Follow the road to the left to reach Châteauvieux.

(6) Pass the Chateauvieux spring, keep right until you reach the church and its two beautiful lime trees. Then turn left onto the road (not the path) and go straight on at the junction, taking the first path on the right, alongside a farm.

(7) At the three-way junction, head up the left-hand path to reach the Crêt de Py-Froid and its viewpoint over the Monts du Lyonnais.

(8) Continue along the path opposite and go straight on at the following junctions. You’ll come to a small tarmac road on the outskirts of Yseron.

(9) Carry on straight ahead. At the crossroads, go straight ahead and then turn left at the next junction onto Chemin du Planil.

(10) At the junction marked with a cross, turn right onto Montée de la Chazière. You’ll come out onto Grande Rue; cross the road and take the path opposite. Shortly afterwards, this path bends to the right to join a road. Take this road to the right. At the first junction, turn onto the small road to the left. Further on, when this road takes a hairpin bend to the right, near a house, continue straight on along the path which leads to the waterfall.

(11) Cross the Yzeron and continue along the path on the other side. Shortly afterwards, ignore a path branching off to the left and continue to the right. Keep following this path until you reach a wider track.

(12) Take this path to the right. Further on, cross the Yzeron again before reaching a road.

(13) Follow this road to the left, then take the first road on the right to reach the hamlet of Le Giraud.

(14) Cross this hamlet by following the road as it bends to the right. Do not continue to the end of the tarmac road but take a path on the left that runs alongside a somewhat overgrown garden. Continue straight on along this path, which crosses the Bois du Faix.

(15) Further on, you’ll find a path branching off to the right, leading to a dolmen amidst a rocky outcrop. A round trip.

(15) Back at the junction, continue to the right to reach a small tarmac road on the outskirts of Saint-Laurent-de-Vaux. Continue to the next junction.

(16) Take the second road on the right. Follow it round the bend and then, immediately afterwards, turn right onto a track. Continue along this track through the Bois de Taconan until you reach another track opposite a field.

(17) Continue to the left to reach a road. Follow it for a few metres to the left, then take the path opposite to cut across the bend and come out opposite the orientation table. Follow the road to the left for a few metres.

(18) Turn right onto a path. Further on, leave the woods behind the Chatanay farm and ignore a footpath and then a path on the left leading back to the farm. Continue straight on until you come out onto a small road.

(19) Walk a few steps to the right along the road, then take the path on the right. Further on, at Château du Montus, continue along the road; then, when it begins to curve to the left, carry on straight ahead along a path. Continue straight ahead along this path until you reach a junction, just beneath the high-voltage power line, with a wide path and a farm track (see alternative route in “Practical Information”).

(20) Continue to the right along the Chemin des Vignes until you reach the hamlet of Basse-Bruyère and come out onto the road that runs through the hamlet, opposite a beautiful house.

(21) Take this road to the left, then take the first small road on the left, the Chemin de la Flache. Pass under the high-voltage line again and continue straight on until you reach a road.

(22) Follow it to the right around the bend, then straight on to the village of Messimy (S/E).

Notes

Shorter alternative: At (20), instead of turning right, continue straight ahead; pass the Maupas property, continuing straight ahead; you will come to a small road and follow it to the right to cross the Chalandraise and arrive at (22).

At certain crossroads, you will find yellow signs indicating the directions.
The main difficulty is the length of the route. Bring a snack or stop for lunch in Yzeron.
Good walking shoes are essential.

Hello,
Done today, perfect weather. 6 hours including a meal break. Long, but not difficult (it’s a constant up and down). However, a bit of signposting would help. But the route description needs updating... there’s some confusion between points 9 and 11... the GPS saved me again
at point (5): you need to turn right, not go straight on
point (6): after the lime trees, don’t turn left, otherwise you’ll cut straight to the waterfall and shorten the hike by a quarter...! Instead, you need to retrace your steps back to the junction and go straight on... there you’ll find the path to Py Froid
point (8): do not ignore the paths branching off to the left; on the contrary, you must take them!
point (15): I didn’t understand the difference between the outward and return legs… no monument or viewpoint… or perhaps I didn’t go far enough?? (yet my GPS told me I’d passed the IGN star…)
At the end, if you’re tired, you can actually cut it short between 20 and 22
In any case, very pretty and enjoyable – a lovely workout!

Great hike, took 5½ hours including lunch break. I followed the route, cutting between points 20 and 22 to stay in the forest as much as possible.
The route is easy, just long.
It's totally doable with a four-legged companion too!

Solo hike on Sunday morning. Left at 7:30 a.m., arrived at 1 p.m.
A superb walk through forests and fields, the route is very well marked... except unfortunately for the last section, which I found quite difficult to follow. I got lost several times in the last few kilometres, which is a bit unpleasant when you're starting to feel tired It might have been easier to cut straight across from point 18 to the return point, as the detour wasn't particularly interesting.
In the end, I didn't meet many people, mostly mountain bikers.

A pleasant hike, but it lacked scenic views.
A bit too long for not enough variety.

Hiking during the week is a privilege for retirees. A lovely route, mostly shaded, which is important in this weather, easy to follow, and the waterfall wasn't dry but wasn't far away. In short, the Monts du Lyonnais with their usual views of the city, the Alps and the Pilat are worth visiting again and again.

A very beautiful hike on shaded paths. Beautiful views and, during hot weather, the opportunity to fill your water bottle at the Chateauvieux spring, where the water is very cool.
Superb

Departure at 8 a.m. on Friday, sunny with clouds, 10°C

Bakery and supermarket in Messimy if needed

Hike combining half paved roads and half forest trails

The hike starts with a gradual climb and ends in Yzeron with a mostly downhill descent

I missed point 5 and took the path that branches off to the left, following the sign for Chateauvieux.

The pleasant part was in Yzeron, after that the landscape was more or less interesting

The roads seem to be used by bikes; I came across people in the woods at Fay

I skipped points 18-21 to shorten the hike.

Total: 20 km in 4 hours 10 minutes at a moderate pace, with an elevation gain of around 950 m

Hello again
Having redone this beautiful route, I have a few positive comments:
- at point 5, the signposting on site takes you on a detour that does not lead directly to the church in Chateauvieux, which would be a shame to miss. In fact, you need to take the road as indicated on the map
- to avoid points 11 and 12 and go directly to 13; then points 19 and 20 to reach point 21. It seems to me that the distance indicated is underestimated, as my GPS showed 20.3 km.
On Sundays, the route is very busy with cyclists, which is difficult on the narrow paths

A beautiful hike in the hills between the Rhône and the Monts du Lyonnais. Stunning views of the surrounding countryside and Lyon in the background. Climb up in the sunshine and return in the shade. Depending on your departure time, you can reverse the direction of the circuit.

Nice hike, very pleasant little villages. Lunch break at the dolmen. As for the waterfall, in my opinion it doesn't deserve to be called that (insignificant waterfall) or maybe I missed something...

The elevation gain was greater than advertised for this hike, but that was fine by me because the more there is, the happier I am 😀

Impossible to see the Alps, too much pollution around Lyon. You can just about make them out, but that's a shame.

The loop from 18 to 21 via Montus Castle isn't really that interesting, and it would be better to go straight from the Pirogoy viewpoint at number 18 to Basse Bruyère at number 21 via Haute Bruyère. Otherwise, it's a very beautiful route that can be done in 5 hours rather than 7 hours and 40 minutes!
Thank you for the warm welcome at the hiking fair in Lyon!
