Description of the walk

Park in the car park opposite Fort de Champvillard.

(S/E) Head towards the fort entrance on your left. Walk around the fort on the left, admiring the moat, escarpment and gate. Cross the road, pass to the left of the roundabout along the car park, then follow the protected pedestrian area along the D127 heading north-west.

(1) Take the path on your left and follow it to a tarmac road.

(2) Continue straight ahead on the path opposite, Chemin de Buye, until you reach a tarmac road and a cycle path. Continue straight ahead on this road. When you enter the town of Charly, take the pavement on the left. Then follow the road to a stop sign.

(3) Take the street on the right: Chemin du Cotentin. Immediately after, turn right again onto Chemin de Béard, which is a one-way street. Continue straight ahead on this street, which becomes a path. Pass two small paths on your left, then take the third path on the left, which is larger, towards Étang de Virieux, Chemin de la Lalande.

(4) Carefully cross the D117, then continue to the pond and walk along its left side. Follow the path into a copse, then continue along the path to the left, skirting a field. At the next intersection, turn right. Continue after a 90° bend, follow the path on the left, then, at the end, turn left again and finally take the path on the right under the power line.

(5) Follow it to a large wall and walk along it on your right. You will then come to a tarmac road.

(6) Follow it to the right, staying close to the road to avoid cars, until you reach the junction with the D117, shortly after a secondary school on your left. Cross the roundabout and follow the road to Vourles opposite. Continue straight ahead, passing a path with a barrier on your left and taking the next left.

(7) You are now following the route of the Deux Forts race, which takes place every July. Follow the path, keeping to the right a little further on, to join the D127.

(8) Turn left onto it, then immediately follow the path on your right. Keep to the right, then turn right again, passing a refuge. Shortly afterwards, on the descent, enjoy the view of Lyon in good weather. Finally, turn right again to reach a tarmac road.

(9) Follow the road to the left, Chemin des Piochettes. After 150 metres, take the small path on the right into the bushes, opposite a hut and after a gate on the left and a concrete kerb on the right. Continue left uphill and discover the Fort de Montcorin. Continue straight ahead, then after a car park and a road on the right, take the path on the right that runs alongside the ditch. Follow the path as close as possible to the ditch and, further on, in the small wood, take a path on your left that will bring you back to a road. Follow it to the right.

(9) Then turn left onto Chemin des Fouillouses until you reach the hamlet of Les Rochettes.

(10) After a 90° bend in the road to the left, follow the path opposite on the left-hand side of the road. Then continue by taking the path on the right, under the power line, to return to the point on the D127 road.

(1) Cross the road carefully, then take the path on the left that runs alongside the road to the Fort de Champvillard car park (S/E).

Worth a visit

Excellent hiking route. We did it on a slightly rainy and overcast day, but we were glad we did. There are beautiful passages between orchards, horse pastures, two farms and two viewpoints that offer a clear view (weather permitting) of Lyon and Mont Blanc. There is very little elevation gain, so it is easy to access. We plan to do it again when the weather is better, to buy some products from the two farms we encountered along the way.

Pleasantly surprised by this route.
Although it is in a suburban area, there is little asphalt, and most of the route runs through orchards.
With relatively little shade, it is ideal in cooler weather.
A lovely view of Lyon and a bit of history about the forts add to the appeal of the walk.

Just one small detail: in point 7, it says to take the path on the left after the one with a barrier. We didn't take it at first, as we were looking for another path because there is a yellow cross on the tree at the entrance to this path. Otherwise, no problems.

The description of the route up to point 4 is fine. At point 5, it is ambiguous: it would be better to say "Follow until you reach a large wall. Turn right to walk along it. You will then come to a tarmac road."
Note: Providing landmarks BEFORE they come into view (e.g. former school at point 6) is not helpful.
After that, did I follow the route correctly? I didn't see the refuge (point 8) - the Piochettes path... hut... At points 8 and 9, I lost track, so I (often) used the GPX track. I am still getting used to this new tool. I had to cut short at the end. Result: 8.6 km. But I think I will do the route again.

Thank you, YR69.
I wanted to be sure that the path was permanently blocked at point 3 before changing the route.
This unnecessarily lengthens the circuit. It's a shame, as the path was lovely.
So I've now changed the route as necessary.
All the best with Visorando.

A lovely, easy walk on flat terrain through orchards. You will encounter horses, a pond, a farm, and beautiful views of Lyon and the two forts.
The administrator should update the information sheet, as it is no longer possible to follow the route indicated in point 3.

Hello,

Indeed, at point 3, the path is now private and requires a detour via the cycle path. Otherwise, it's a pleasant route through orchards and fields, with a beautiful view of Lyon at the end of the hike. Follow the description carefully, as there are many paths and a moment of inattention can lead to a mistake in direction.

We were unable to follow this route, which was blocked at point 3 by local residents, perhaps because of the nuisance it caused?

We attempted to do this hike yesterday, Wednesday, 4 October 2023.
it is no longer possible to do this hike because three local residents have blocked the trail. It's a shame. Perhaps they are victims of nuisance?

A lovely route between two forts, winding its way through fields and orchards that are beginning to bud, with panoramic views of the Alps, the Monts-Lyonnais and the Lyon metropolitan area.
A pleasant encounter with families out for a stroll and hikers.
Thanks to the author for this new discovery, which is best enjoyed during the fruit blossom season.

A lovely route near Lyon with two forts, not too crowded on this autumn Sunday.
Lovely views of the Alps and Lyon on a clear day, lots of wide paths through the region's different crops. Completed in 2 hours 50 minutes without any problems. If you want to picnic, there are a few benches around the Virieux pond.
The GPS got a little lost in the woods at the end after Fort de Montcorin, but it was easy to find the road again
Thank you for this route.

A very easy but very pleasant hike. The two forts, at the start and finish, are surprising and unexpected, just outside Lyon. The hike took 2 hours and 5 minutes at a leisurely pace, with lovely views of the Monts du Lyonnais.
