There are yellow signs all along the way.
(1) Start at the end of the car park (information sign). Take the boardwalk heading north-east, which takes you below the lake.
Caution: there are no barriers or guardrails, and the planks are uneven.
There are information signs along the route at points of interest. At the end, return to dry land and continue to a customs hut that is currently being restored.
(2) Head east-southeast to cross the salt marsh on the planks. Once on the other side, the boardwalk goes around a small bump on the left.
(3) At this point in the walk:
- either turn right to climb to the top of the hill for a 360° view, then descend to the edge of the salt marsh and continue south-southwest to La Passière (this is the option shown on the map).
- either continue along the edge of the pond on the main path to reach the edge of the Doul pond.
- or join the edge of the salt marsh on your right. N.B. Due to wildlife protection, this third option is not available at certain times of the year.
(4) Turn left (east) onto the path that climbs towards Le Mour. The path is lined with wires and posts to prevent hikers from trampling the flora. Caution: from the sign, the path climbs steeply. The trail skirts around the Mour on the left to avoid excessive erosion caused by both hikers and rainfall (repair work in progress), before finally turning right and continuing to the summit.
(5) Retrace your steps and descend to the right along a path that winds through the vegetation towards the small marina and fishing port.
(6) Turn right (north-west) to return to La Passière.
(4) Turn left, pass between the salt marsh (on your right) and the Peyriac pond (on your left). Then turn right to reach Peyriac along the roadside (which has been developed).
