Start from the supermarket car park on Avenue des Platanes.
(S/E) On leaving the car park, turn left. After 100 m, turn left onto a small road, then carry on straight ahead along a track. When you reach Route de l’Hermitage (D 287), turn left until you reach the roundabout and turn right towards the entrance to Château de la Chênais.
(1) Take the path on the left which goes round the château. After passing the rear entrance to the château, take the first path on the right, then the first on the left. Carry on straight ahead to Rue Jean Moulin and follow it to the left, then continue to the right along Rue François Mitterrand until you reach the roundabout.
(2) Turn right, then immediately left onto a path (les Communs). Continue along the path which follows the River Vaunoise. At the crossroads of paths near a bridge, turn left past the allotments, then right.
(3) Here, the Vaunoise flows into the Meu. Follow the Meu as far as the Parc du Pressoir.
(4) On leaving the park, cross Avenue de Lorient with care and follow the path on the right which leads back to the Meu. Follow it further to the Moulin de Mordelles.
(5) Go round the mill on the right, then turn left towards the stadium and walk on for 50 metres.
(6) Continue to the right, with the Étang de la Biardais on your left. Follow its southern bank. At the far end of the large pond, turn right, then left onto a footbridge. Follow the path between the two small ponds and the Meu. Reach the roundabout on the Route de Chavagne via the grassy path, then take Rue des Perrières on the right.
(7) Cross the Route de Chavagne and follow the path in the corner between the two roads, keeping the factory on your left. After walking past some blocks of flats, continue along the path running parallel to the road.
(8) Walk past the reconstructed remains of a fanum – a Gallo-Roman temple – and reach the supermarket car park after crossing Avenue du Maréchal Leclerc (S/E).
