Cousseau from Marmande: the complete visit
Start at Marmande parking on the D6E1 between Le Huga and Carcans-plage. Follow the signed approach towards Cousseau and the Lesperon entrance, then use the marked interpretation circuit and viewpoint paths before returning to Marmande. The published total is 7.5 km, including the approaches. Think of it as a proper half-day walk: save energy and water for the return after you have spent time watching the marsh.
Gironde Tourisme rates the route medium difficulty. Dune climbs, gravel and stairs make the complete itinerary unsuitable to describe as wheelchair-accessible or pushchair-friendly without individual advice.
