Straddling the communes of Jullouville and Saint-Pair-sur-Mer, the mare de Bouillon is separated into two parts by a dike where the river Thar flows. It takes its name from theformer commune of Bouillon, which became part of the seaside resort of Jullouville in 1972. Around its edges, plant belts have developed: reedbeds, meadows with tall herbaceous plants, willows… Long privately owned, it belonged to the Garnier family, major publishers, and was a popular spot for fishing and hunting.

Acquired in 2011 by the Conservatoire du Littoral, this natural setting, adjacent to an urbanization zone, is a regular sanctuary for numerous bird species such as cormorants, herons, great crested grebes, coots and ducks (mallard, shoveler, teal…). Not accessible to the public, it can nevertheless be seen in autumn or winter from the “Route de Boislerey” viewpoint in Jullouville, or all year round after taking the roundabout.After 200 m, turn right onto a footpath (viewpoint with information table).
