Hiking circuit - La Banche and la Brune

It's the walk of the three canals: the two drainage canals of the Marais Poitevin pass in siphon under the Marans canal in La Rochelle.

1. Cross the bridge, pass in front of the old lock keeper's house and follow the canal from Marans to La Rochelle.

2. Cross the bridge, avoiding crossing the road. Go down on the other side and go up towards Marans. We arrive at the Banche canal bridge.
