Plage de Mardi Gras lies at the southeastern fringe of the Bois de la Chaise, Noirmoutier's storied maritime forest, where footpaths twist beneath evergreen oak canopy and cottages peek from hedgerows of tamarisk. The beach itself is a crescent barely fifty meters wide, framed by low rock shelves slick with wrack and studded with barnacles. At low tide, shallow depressions pool with seawater warm enough to wade barefoot, and children crouch to net translucent shrimp darting over ribbed sand.
“One of the Bois de la Chaise's lesser-named coves, it offers oak-canopied seclusion without the crowds that gather at neighboring Plage des Dames.”
Crystal lagoon with rocky outcrop
Unlike the family-friendly sprawl at Plage des Dames a kilometer west, Mardi Gras draws couples and readers who settle onto striped towels in the shade of wind-pruned pines. The slope is gentle; you can walk thirty meters out and still feel ridged sand beneath your toes. Sailboats tack across the Passage du Gois in the distance, white triangles against the haze of the mainland.
Come an hour before sunset. The western sky floods rose and apricot, the oaks darken to silhouettes, and the retreating tide leaves mirrors of sky on the flats. There are no beach clubs, no loudspeakers—only the rhythmic scrape of wavelets on shell fragments and the occasional cry of a gull wheeling over the point. You leave as you came, up the wooded path, salt drying on your calves.
