Marais Barrage: from Maison Béziers to the pumps
The manager currently gives 6.4 km return. Begin at the visitor entrance, pass the educational marsh and follow the signed discovery path. The official plan names the hides Les Plumes, Les Pattes and Les Becs before the elevated observatoire des pompes. Return by the same authorised path. Allow 2½–4 hours including pauses; turn around earlier if you prefer a shorter outing. The out-and-back layout is useful because you can choose your own stopping point without committing to the far end.
This is a walking route with boardwalks, embankments and observation structures. A flat-looking map does not establish a step-free journey. Wheelchair users should arrange a shorter, confirmed section.
