The walk starts at the end of the village of Kerven,
(S/E) Start the walk on the path after the barrier and follow the marsh on your left until you reach the observation point.
(1) Take advantage of the observation point to identify bird species. Continue along the path that crosses the marsh. A longer alternative is possible by going straight ahead to the pier and then walking along the campsite on your right
(2) Walk along the D111 on the left. The path is far from the road, so there is no risk, even with children. Go through a roundabout and you will reach a new observation point.
(3) At the new observation point, follow route 1 to the left into the marsh.
(4) From this new observation point, continue along trail 1 to return to the starting point (S/E).
