Monts du Lyonnais. Circular from Courzieu to Yzeron via Crêt de la Madonne

Meadows, orchards and woods follow one another on the hillsides where, from late spring to early summer, raspberries, strawberries, cherry blossoms and other red fruits flourish. The contrasting plots of land create a very varied and pleasant landscape, including wooded areas of oak, chestnut and hornbeam coppices. Exceptional panoramic views of the Tarare mountains (particularly from the "Lafont" orientation table), Lyon and the Ain plain. Virtually no tarmac. Pure bliss!

Description of the walk

Preliminary remark: follow the description and the signs on the ground carefully. The Rhône department has made great efforts in this regard, but some sections have only been very discreetly marked. The places indicated "in quotation marks" in the description are all marked on the ground and on the maps published by the Rhône department on an IGN 1/25,000 scale background, "les vallons du Lyonnais" and "le pays de l'Arbresle".

Start from the car park of the Courzieu multi-purpose hall located on Route de la Verrière (Route de Montromant), also known as the hikers' car park.

(S/E) With your back to the car park, go up to the right and follow the signs for "Chazeau". Pass above the boules court.

(1) Turn right onto Chemin du Chazeau and follow the yellow markings. At the next crossroads, turn left.

(2) At "Chazeau", continue straight ahead. Pass a calvary on your left (there are usually greenhouses on either side of the path at this point) and at the three-way junction continue to the right.

(3) At the "le Maroge" fork, go straight ahead and keep left on theGR® marked in white and red.

(4) At a place called "Les Avergues", continue on theGR®7via the "Chemin du Pêcher". Walk along a pond and then follow the edge of the woods.

(5) Pass through "Le Futerer", cross the D25 and continue on theGR®7to "La Fromenterie".

(6) Cross the D489 with caution and continue on theGR®7towards "Les Brosses".

(7) Shortly after "Les Brosses", turn left towards Yzeron (signs are often damaged), leaving theGR®7which continues straight ahead. Reach Yzeron (yellow markings). Pass through "Le Plat" and follow the signs for "Yzeron, Plan d'eau du Ronzey" on the left. Walk around it clockwise (there are plenty of places to picnic, a picnic area at the end of the lake, and public toilets near the dyke).

(8) Leave the lake and join the main road. Start descending the road for about 150 metres.

(9) Turn left onto Chemin des Bruyères. Continue along Chemin des Pins on the right. At the bend, turn right onto a short dirt track.

(10) Join the "Chemin du Vayen" marked in yellow, which turns into a grassy path before reaching a road. Follow it carefully on the right for about 200 metres. The yellow markings then indicate a left turn.

(11) Take a barely visible path on the left, which starts before the yellow-marked cross, and follow the markings that lead to "Crêt de la Madone" via a fairly steep slope. Continue towards "Pimongon", first along a path through the woods, then along a small exposed ridge road, always following the yellow markings.

(12) Pass in front of the hamlet of St-Clair and continue along this small road which leads to the tiny
"Chapelle St-Clair".

(13) At the "Chapelle St-Clair", leave the road on your right and pay particular attention at this fork in the road. Take the path that is not very visible from the road and which passes under the chapel towards Courzieu via "La Petite Vernay" marked "fraise blanche". The narrow path first descends gently, then joins a good path that runs flat to the right. Follow it to "La Grande Vernay".

(14) At this crossroads, take the path that descends to the left towards Lafont, and immediately a few metres further on at the fork, take the right-hand branch "Madame Moutot", which you should follow to the top of "Lafont" where an orientation table offers an exceptional 180° view.

(15) Reach the hamlet of Lafont then Courzieu via the "strawberry route", follow the markings carefully, cross the road by making a first turn right then left, and reach the three-way junction with a calvary. Follow the right-hand branch and reach a small hamlet. Pass a first house then a small square building right on the edge of the road.

(16) Immediately afterwards, leave the road and take the narrow path that passes between the last two houses in the hamlet. The house on the right has a staircase at the front and the house on the left has a truncated roof. Head towards Courzieu and the car park, which is clearly visible. Turn left onto Chemin de la Croix Rousse, then Route de Malval, Rue du 8 Mars 1962 on the right, Monument aux Morts, and finally Route de Montromant (also known as Route de la Verrière). You will reach the car park of the multi-purpose hall (S/E).

Notes

Halfway along the route, there is a picnic area at the Ronzey lake (Yzeron).
Most of the elevation gain is in the morning, but the short climb to Crêt de la Vierge overlooking Yzeron gives your digestion a boost.

Worth a visit

There are many aqueducts a few dozen metres from the trails. They are marked with a logo.

 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.

Hike done in autumn with magnificent colours, quite cold and muddy but still interesting as the route is not too difficult. I recommend this route without hesitation

Thank you for your feedback.
Indeed, for a restaurant, it would be better to start this circular in Yzeron
Kind regards.

Hike completed in just over 5 hours this morning, between 7:30am and 12:30pm. Very pretty scenery, the view of Lyon is excellent and the shaded sections are welcome when the sun starts to beat down.
I only came across a few hikers (four, I think), a few mountain bikers/motorbikers and some families at Lake Yzeron.
No problem following the route with a GPS or the app.
Just disappointed that there were no restaurants open at the finish.

Beautiful hike, magnificent weather. Varied route with a lovely climb up to Yzeron in the morning, a break, a good climb up to La Madone, then descent to Courzieu. Easy route, with just a slight difficulty after Saint-Clair in finding the right path. About 5 hours of walking, including breaks. Beautiful views of the valleys; open paths and forests, very pleasant!

A beautiful hike with stunning views of the Forez and the Rhône Valley. Personally, I used the GPX track on my Garmin GPS, which was very accurate. My GPS recorded a total distance of 18.6 km. This is one of the hikes in the Monts du Lyonnais with a significant elevation gain (> 650 m). It took 5½ hours to complete.

A superb hike with splendid views along the entire route. The climb to the Madonna is a little steep but not difficult.
You can't go wrong with a good map and a hiking GPS.
Thank you

A superb hike with very varied landscapes:
You pass through orchards (cherries, strawberries), fields (wheat, corn), meadows and numerous woods, alternating between beautiful views of the surrounding area and the cool shade of the undergrowth as you walk beneath fir, walnut and chestnut trees...
A hike just the way we like it, where all your senses are awakened!
I only used the map via the Viso app and all the points are perfectly placed, so if you check your phone frequently, you can't go wrong (even at point 10).
The hike took place between 9:45 a.m. and 2:45 p.m. with a picnic break at Lake Yzeron. As it was a weekday, I didn't meet anyone else along the entire route!
In short, I recommend it 100% with the GPS map.

Thank you for your comment. I have revised the description, adding more details and a waypoint, but without mentioning the no entry sign as it is a mobile sign. As it happens, by pure coincidence, I was also on the same hike on Sunday.

Please note that on the way back, in the forest between St Clair Chapel and Courzieux, a no-entry sign, if obeyed, leads to a path that becomes very dangerous, with a steep downhill slope. In fact, you have to take the no-entry road!

we completed two-thirds of the hike very easily; the directions were perfect
however, we never found the orientation table, even though we took the right path after the four paths (white strawberry) and then Madame Moutot's path to the top.
there we found ourselves on a road with a dirt car park and no signs for this famous orientation table or for the place called Laffont
we already had 15 km under our belts
and had trouble finding a road back to Courzieu
so we ended up walking 23 km
so the end of the hike wasn't great
it's a shame because the beginning was really well signposted
and we didn't understand!!!!

Departure at 9:45 a.m., return at 4:50 p.m. Beautiful weather, a little cool, ideal for walking.
We don't use GPS, which sometimes leads to a few interesting route errors . For example, we turned off too early before point 7 towards Yzeron. We passed under the Pilon farm and then descended through a north-east facing valley to the top of Lake Ronzey. From there, there is a beautiful view of the lake, Yzeron and the Alps. We "caught up" with the route by passing through Monterou. Furthermore, from the description, we understood that the Chapel of Saint Clair was at point 11, but the Chapel of Saint Clair is at point 12. From this point onwards, following the white strawberry trail without GPS, it becomes difficult to find your way. That is why, at the "La Vernay" signpost, in front of an old restored house, we headed towards Yzeron (passing through "Le Grand Bietto" if you look at the map). This route is quite isolated and wild and takes you through a north-west facing valley to the remains of the Brévenne aqueduct.
That said, despite these mistakes along the way, we never felt lost and had an excellent day. Walks without GPS become an enriching exercise when you don't have a great sense of direction.
