(S/E) Head towards the river and turn left to walk along the right bank of the Sèvre.
Go under the D1 road bridge and continue along the Sèvre Niortaise on the cycle path.
(1) At Marais Pin, note the dam and lock. Continue straight on to Magné.
(2) Turn right to cross the Magné drawbridge. About 50 metres after the bridge, turn left onto Ruelle du Port de la Cure, which passes behind the church, and join Avenue du Marais Poitevin. Cross the avenue and turn left to take the pedestrian crossing between the red barriers, to the right of leat Saint-Germain. Go up Rue de Bétitame and turn left when you reach Grand Rue.
(3) Turn right onto Rue du Clouzis. After the houses, continue straight ahead on a road lined with hedges that descends (Route des Groies).
(4) Turn left onto Chemin de la Fontaine Sainte-Macrine, which is not a path but a small tarmac road. Note the fountain in question on the right-hand side of the hill. At the top of the hill, turn right just before the water tower. After the houses, continue along a white path that is closed to traffic.
(5) Once you reach the road, immediately turn right onto a grassy path. It is also possible to continue along the road to pass in front of the Sainte-Macrine Chapel, patron saint of the Marais. In this case, rejoin the route by turning right after the chapel.
After the path, follow the road that runs alongside a pheasant farm to the hamlet of La Brémaudière. Turn right at the hamlet. Go down the road until you reach Chemin de la Cabane on the left after the house.
Continue along a white path.
(6) Cross the Conche des Épineaux and then, after two bends, another footbridge. After about 200 metres, cross two more footbridges in succession to continue on a path between a fence and a ditch until you reach the Cabane des Épineaux. Continue along the road and turn left when you reach the Route de Monplaisir.
(7) Carefully cross the D1 and take the path on the right that runs alongside the road, separated by a hedge.
(8) Continue along the path to the left, which joins Chemin de la Repentie (a small tarmac road). Turn left to reach the street on the left bank of the Sèvre. Turn left onto it.
(9) Cross the footbridge to reach the other bank, then turn left and a little further on to the right to reach the starting car park (S/E)
Leave the path after the roundabout and continue carefully along the road. Cross the Vieille Sèvre de la Repentie (be careful, the pavement is very narrow) and a little further on, on the left, you will reach the starting car park (S/E).
