Description of the walk

(S/E) Leave the cemetery car park and continue uphill towards the church. Take the time to see if it is open. If so, go inside. The interior contains some amazing modern frescoes.

Leaving the church, continue along the road of the same name, ignoring the road that climbs to the left. Two signs limit your speed to 20 km/h and the weight limit to 3.5 tonnes. This should not be a problem. Very quickly, you will reach the sign for "Champ Carreau - alt. 385 m".

(1) Continue along the small road. You will come to another tarmac road. Turn left and you will reach a T-junction. Turn right (Chemin du Fouilleux). The small road curves to the right. Shortly afterwards, turn left opposite a concrete cross and you will come to a T-junction with a sign for "Le Fouilleux - alt. 440 m".

(2) Turn left towards Royas. Very soon, you will come to a fork with a sign for "Pounatière - alt. 440 m". Turn right onto Chemin des Grimaudes. Follow the yellow markings until you reach the departmental road at Charantonnay.
When you pass Chez Escoffier (an isolated house on your left), take the path that descends to the left towards the forest, which leads to a track further on.

(3) You will see a sign for "Les Grimaudes - alt. 385 m". Turn right. Very quickly, you will come to a small road in the middle of a circular route. Go up to the left. After a hairpin bend, you will come to a rough stone wall. Take the path that goes up to the right and quickly leave a path that comes from your right.
Pass a sign for "Bois de Molèze - alt. 450 m" and continue towards Charantonnay. At a T-junction, turn left (still following the yellow markings). You will see a bright field and come out at the edge of it, with the sign for "Bois des Crottes - alt. 460 m" on your left.

(4) Turn left. Until you reach Charantonnay, the yellow markings are missing in places. However, there are orange circles that you can follow in addition to the description. First, descend steeply, then climb slightly and descend again to the Charantonnay valley. Ignore the faint paths on either side. Once you reach the valley, you will come to a small road which you take on the left. Cross a small bridge and you will arrive at the main road.

(5) Turn left. Be careful! Traffic moves fast here. After 100 metres, turn left into Impasse du Héron. You will see the hill in front of you and you will have a good idea of what lies ahead... you will indeed be climbing back up to the top.

(6) You pass a small pond. Ignore the two paths that branch off to the right and take the more discreet path opposite you. (e) It climbs up the hill and you can see a field on the left through the trees.

Shortly after the slope levels out, you will see a light grey metal sign on your left with the words "ACCA limite" written on it. Take the discreet path on your right. Further on, you will come to a cultivated area, which you will cross. You will come to a small poplar plantation and turn left. Ignore the path that branches off to the right after the poplars and you will arrive directly beneath a high-voltage power line.

(7) Turn right. After a while, your path becomes paved. You will come to a small road, which you will follow downhill to the left. A little further on, ignore the yellow markings that direct you to a path on the left and continue down the small road. You will arrive at a T-junction in the hamlet of Le Colombier.

(8) Turn left, crossing a small bridge (Chemin de la Saunière). When the small road curves to the right, you will see a fountain. When you reach a fork, turn left. You will come out higher up in the fields. Your path curves to the right, heading towards the hamlet of La Champillonnière.

At the end of the hamlet, your road turns left and you take the dirt track on the right. It very quickly turns left. At the end of the field, you can see the statue of the Madonna opposite you, slightly to the right. Your path descends and turns right before reaching a sign for "La Madone - alt. 450 m".

(9) Go up to the right to reach the Madonna site.

(10) In addition to the statue, there are two orientation tables and two picnic tables. It is a shame that the view is partly hidden by vegetation. Turn around.

(9) When you return to the sign for "La Madone - alt. 450 m", descend to the right. When you reach a flat area, look to your left to see a rather interesting statue of Christ on the cross. At this point, be sure to take the very discreet path that branches off to the right. You will come out onto a small road, which you take on the left. You will soon arrive at the church. Turn right to descend to the cemetery car park (S/E).

Notes

The walk is located in Beauvoir-de-Marc, in northern Isère, a few kilometres north of Saint-Jean-de-Bournay.

To reach the start of the walk, leave the main road and head up towards the church on the small road that rises up from the bakery (Chemin de l'Église).

As the route is not far from St Ex airport, you may or may not have planes flying overhead, depending on the wind. This may be a nuisance for some.

We are in a relatively urbanised area, so about half of the route is on small asphalt roads, with the rest on wide dirt tracks.

On the roads, follow the usual rules: walk on the left-hand side of the road, in single file. If there are a lot of you, place a scout 20 metres ahead and a rear guard 20 metres behind.

There is a fountain in the hamlet of Colombier.

Near the Madonna, there are picnic tables.

There is a very good bakery in Beauvoir. For other shops and services, you will need to go to Saint-Jean-de-Bournay, a few kilometres to the south.

Worth a visit

The chapel of Beauvoir, with its astonishing modern frescoes inside, dates from the 11th century. The building is splendid. A mural depicting Saint Anthony can be found in the apse of this medieval church. The coffered ceiling of the nave has been reconstructed and painted. The two tympanums above the entrance doors to the transept arms have been listed as Historic Monuments since 28 January 1958.

At the end of the trail, you will arrive at the Madonna overlooking the village. There are two picnic tables and two orientation tables. At the very end, you will pass an interesting modern crucifix.

Hike today in good weather. The route description is clear and poses no particular problems. After the rains, there are many muddy sections, but the terrain is almost flat, slippery on the slopes. There are magnificent trees in the woods on the way down to Charantonnay. After point 6, the small path is discreet, but clearly visible in winter.
Please note: The Madonna above Beauvoir de Marc is currently being restored and is therefore surrounded by scaffolding.
Duration of the hike: 3½ hours for a group of 20 people over the age of 65.

The route is well explained and very pleasant, but a little muddy as it had rained a few days earlier.
There was a slight issue at point 6, near the pond. To find the path, you have to go behind a barrier that seems to have been put there to prevent hikers from passing. We took another path that led us through a woodcut, which was not very pleasant. A shame! Otherwise, it was a lovely hike.

We went on this hike and everything was fine until we reached the pond, but then things got complicated because of some woodcutting debris blocking the path. We had to cut straight through the construction site to quickly reach higher ground and assess the situation. We got a little lost because instead of arriving in front of the poplar plantation, we arrived with the poplars on our right. But after walking another kilometre, we found ourselves back on the path passing under the high-voltage line. All in all, it was a beautiful hike and the picnic tables at the foot of the Madonna are very nice.

A varied and breezy route on a windy day, offering views of the Pilat massif, the Monts-Lyonnais and the Alps, which were visible today.
We crossed the hamlet of Le Colombier with its typical forestry workers' houses on our way to Charentonnay, ending up at a beautiful spot near La Madone with a stunning view.
Thank you to the author for this new discovery.

A pleasant hike without any particular difficulties, with a picnic break at the Madonna of Beauvoir! We'd be delighted to do it again.

A lovely walk, not very busy as it was during the week. A bit of a narrow road at the start, but nothing too bad. You can have a picnic at point 6 near the small pond. However, we looked for "les Crottes" (the droppings) ... ha ha...
