Start from the car park at Saint-Vivien cemetery, behind the church (difficult to find; coming from La Rochelle, after Saint-Vivien town hall, turn right towards the church).
(S/E) Head east towards the back of the car park. Walk alongside a rainwater retention basin. Cross the tarmac road by first turning left then right and take Rue de l'Ermitage. Continue through the fields.
(1) After about 1 km, turn left towards the Moulin de la Pierre campsite. Cross the tarmac road (D205, caution: heavy traffic) and walk alongside the campsite.
(2) Take the first path (paved at the beginning) on the right after the campsite. Continue straight ahead. When you reach the paved road (D11), cross it and follow the dirt path opposite, slightly to the right.
(3) When you reach another tarmac road, turn right and follow the road for 50 metres, then turn left towards the farm selling direct produce, Les Coutures.
(4) Turn right at the first road after the farm. Continue straight ahead and enter Thairé via Rue de Verdun. At the corner of the cemetery, turn left towards the church.
(5) Go around the church on the right, turn left and pass in front of the post office. Take Rue du Baloir opposite.
Pass under the house that spans the street. This curious construction is called the baloir. Turn right onto Rue de la Corderie.
(6) Turn left onto Rue de la Liberté and walk on the left-hand pavement, which is wide enough. After 200 metres, turn right. After about 500 metres, continue straight ahead on the dirt track.
Cross a road and continue straight ahead on the path that continues opposite.
(7) At the end of the path, when you see two farms (the one on the left has large, noisy but not aggressive dogs that may come towards you), turn right onto the tarmac path and then turn left to join the D110. Turn left (towards Voutron). Walk carefully for 300 metres along the road.
(8) When you reach the canal, turn right onto the path furthest to the right on the marsh embankment. Follow this path between two canals for about 2.5 km.
(9) At the end of the path, facing a barrier, turn right. Pass between the farm buildings; the ground may be very muddy. On the tarmac, turn right to reach the crossroads from the outward journey.
(1) Turn left and follow the same route back to the car park at Saint-Vivien cemetery (S/E).
