Start: from the Passe aux Boeufs car park, west of the town of Port-des-Barques.
(S/E) With your back to the car park entrance, turn left onto a sandy track (Passe aux boeufs causeway) that descends slightly. Follow the gravel path west-northwest to the island.
(1) Once on the island, at the fork at the Pointe de Surgères (oratory), turn right onto a small tarmac road. Take an opening in the hedge on the left to cross a meadow and reach the Croix des Galets (cross-shaped pile of pebbles, information panel).
(2) Reach the road further north and follow it to the left.
(3) At the Virgin statue, leave the road and turn left, then right onto the footpath (pontoon over the sea on the right). Follow the hedged path along the coast. The path becomes narrower, cross a footbridge and emerge onto a small beach with a masonry structure (the Puits des Insurgés).
(4) At the fork, turn left towards the fortifications (sign). Follow the first fortifications, then walk between two hedges. Just before you reach the tarmac road, turn left onto a path that runs parallel to it. Walk past the war memorial to a roadside barrier. Turn left through the barrier to reach the entrance to the fort.
(5) Retrace your steps to the fork near the small beach.
(4) Turn left and, after just a few metres, take the stairs on the left (the path opposite leads to a cul-de-sac). Skirting a field on your left, head towards the houses, which you pass on the left. Before reaching the road again, turn right onto a path that runs between two houses. Turn left and follow a beach (on your right) and a car park (on your left).
(6) Cross the tarmac road running north-west towards Plateau des Palles (information sign) and head due south on a wide gravel road. Follow the coastline (carrelets), pass the path on the left which leads to an aquaculture farm and cross a stream.
(7) Continue straight ahead (south-south-east), still along the coast. The path turns east, then north away from the coast, then east again. Follow the path between the pastures and ponds of the aquaculture farm, and find the Pointe de Surgères oratory.
(1) Take the Passe aux Boeufs causeway in the opposite direction to the outward journey to reach the start car park (S/E).
