Park along Avenue Georges Bassinet at the Pavillon de la Rotonde, 200 metres before the Casino when coming from the town centre (Ruisseau de la Beffe marker).
(S/E) Take the path that climbs towards Le Clapy. Walk alongside the municipal swimming pool to reach the "Clapy" marker, a wooden barrier.
(1) Turn right onto the Prés-Mouchettes path towards La Thuillière.
Join and follow a small road on your left for 100 metres. Turn right onto Chemin des Pins until you reach the D307.
Cross the D307 carefully, follow it for 50 metres and take thefirst path on your left.
When you reach the body shop, turn left onto Chemin de la Thuillière.
This road descends into the valley to reach the Sentier Nature du Bois de Serres nature trail.
At the La Thuillière marker, continue towards Jansavon. Follow the Ruisseau des Planches stream, pass under the railway viaduct to reach the "Jansavon" marker.
(2) Take the path on your left that goes up towards Bois de Serres and Dardilly.
Cross the railway line via a bridge. Follow the track which runs alongside information panels and passes close to a boundary marker dating from Year VIII, to reach the "Bois de Serres" boundary marker.
(3) Turn left towards Les Mouilles.
At the roundabout, turn left onto Chemin des Mouilles until you reach the boundary marker of the same name.
(4) Take Chemin du Bois de Serres on your right until you reach the "Cogny" boundary marker.
(5) Turn left onto Chemin de Cogny to reach the boundary marker and the Viroules cross.
(6) Turn left onto the road that descends towards Bas du Crêt.
At the "Bas du Crêt" marker, take the path on the left to the Chantemerle valley.
(7) Turn left towards Les Mouchettes. Cross the pontoons to cross the wetland area of the Planches stream, then walk up the valley. Continue to the D307.
Cross the D307 carefully and continue opposite on Chemin du Bois de Cros.
Leave the road leading to a nursery on your right and take the road on the left.
(8) At Les Mouchettes, turn right towards the pond.
Cross the equestrian centre and at the Étang marker, turn right towards La Beffe. (Ignore the yellow cross).
(9) Turn left onto the Beffe path, which descends into the valley of the stream of the same name.
Take the footbridge to cross the stream and walk up the valley towards the racecourse. Ignore the paths on the right.
(10) At the racecourse, turn left towards Bois de la Lune.
(11) At the "Bois de la Lune" signpost, turn left towards the pond.
At the next fork, leave the main path that descends into the Beffe valley and follow the path on the right. (Ignore the yellow cross on the tree.)
Pass by a pond and walk alongside ruins with animal targets from an archery range.
The path descends steeply to cross the Ruisseau de la Beffe and join another path. Turn right to reach the Casino car park. Cross the car park, then the roundabout, and return to your starting point. (S/E)
Lots of undergrowth. Many small paths or rather small roads. This doesn't bother hikers, but if you have an animal with you, you often have to put it on a leash. That's a shame in this case. But worth doing again in warm weather.
It's perfect in all seasons because it's mostly shaded and has beautiful scenery. When there has been heavy rain, the Bieffe stream is no longer crossable after point 11 (without getting your feet wet...). I found another descent just before this point: take the narrow path that branches off to the left just before you start the descent through the rocks indicated on the route (you can see this path on Google Maps). This takes you directly down to the stream upstream from the point indicated on the route, at a place where it is still not very deep. And as a bonus, I think it's a beautiful natural area. Then continue along the only path to reach the end of the route at the car park.
