Start from Aytré Plage station.
- Access by TER train, on the line between La Rochelle and Rochefort.
- By car: park in the station car park.
(S/E) With your back to the station, turn right onto the path – initially tarmac – which runs between the houses; you’ll soon reach Boulevard de la Mer. Turn right, keeping to the wide pavement on the right, until you reach a roundabout preceded by a bus shelter.
(1) Walk past the bus shelter on the right and take the dirt track that leads down into the Marais Doux. Ignore the first path on the left and continue to the right, then straight on through the marsh until you reach a road. Walk parallel to this road, heading off to the left.
(2) The path is now right on the edge of the road. There is a campsite on the other side of the road. When you reach the Pont de la Pierre, do not cross the bridge but carry on straight ahead until you reach a level crossing.
(3) Carry on straight ahead after the level crossing. Turn left along the car park and go round the back of the sailing club.
(4) On the left, take the footbridge for pedestrians and cyclists and carry on straight ahead. Walk past a wastewater treatment plant on the right. If you wish, you can walk round one of the plant’s ponds (information boards). Carry on straight ahead until you reach the tennis courts.
(5) After the tennis courts, turn right and continue along this path for approximately 2.5 km. Note a renaturalised oyster farming area on the right. Here you can spot birds such as egrets and herons. The path leads out onto a road next to a restaurant. Cross this road.
(6) Climb the few steps leading up to the sea wall. Walk along the sea wall, keeping to the right, until you reach a boat launch. Leave the launch on your left and follow the tarmac road for 50 m.
(7) A wide path climbs to the left towards Pointe du Chay. Take this path. Halfway along, a gate marks the boundary of private property. Take the path on the left which runs alongside the fence of this property and you’ll reach a blockhouse.
(8) Turn right. Walk behind the blockhouse and follow the path marked by two wires on the right and left. Do not stray from the path. There is a beautiful panoramic view of the islands and the Bay of La Rochelle.
Leave the cliff edge and head back down a path alongside a fence, keeping the fence on your left. When you reach a tarmac road, turn left and walk for about a hundred metres until you reach another boat launch.
(9) Turn right onto the coastal path, cross a wooden humpback bridge (see photo) and continue to the end of the path.
(10) Walk past the small sailing club building on your left (open in season). Head down to the beach and walk back to the starting point along the sand for about 1.5 km.
(11) Turn right to cross the railway line at the level crossing. Immediately turn right again to reach Aytré Plage station (S/E).
