At a place called l'Arche du Dareau, there is a small car park on the left, opposite Rue de la Bourdinière, which is the starting point.
(S/E) Continue along Rue de la Sensive (north-west).
(1) Pass the first canal and its small shipyard, which is still in operation, then turn right at the fork. Follow the road to the first intersection.
(2) Turn right, then take the first left after about 600 metres.
(3) At the next crossroads, turn right. Pass through La Chalandière and you will come to another crossroads.
(4) Turn right. Ignore the small road leading to Le Ruaud on the right and pass through Le Cadoret. Continue until you reach the "Give Way" sign.
(5) Turn right and continue straight ahead for about 1.5 km until you reach the stop sign.
(6) Turn right to enter the hamlet of Étang Bernard, which rises just a few metres above the marsh. After 100 metres, at a fork, turn right again onto Rue du Château. After 100 metres, take the small road that goes up to the left (Chemin de la Grimaudière), then follow it until you return to Route des Pélerins at the stop sign.
(7) Take this road on the right. Leave Étang Bernard and, at the next fork, take the road on the right for 300 metres.
(8) Take the path on the right. If this path is too muddy, which can happen, continue along the road and turn right at the next junction.
(9) Back on the road at Mortier des Noues, turn right and continue to the junction with Rue de la Bourdinière.
(10) Turn left and return to the car park (S/E).
... Best to do this hike again in spring to observe life around the water sources.
