The marsh is one of the last remaining coastal wetland habitats along the Calvados coastline.
The site hosts over 150 identified bird species, including rare migratory visitors.
It utilizes a 'gentle' ecological management system, including grazing by specific hardy cattle breeds to maintain open meadows.
The marsh acts as a natural sponge, playing a key role in flood regulation for Villers-sur-Mer.
The area is home to the protected Southern Damselfly, a species highly sensitive to water quality.
Le Marais de Villers-sur-Mer is a 32-hectare protected natural area consisting of coastal marshes, wet meadows, and reed beds. It serves as a critical biodiversity refuge for migratory birds and local amphibian populations. A system of wooden boardwalks and gravel paths facilitates pedestrian access through the sensitive wetland ecosystem. The park functions as a natural water filtration zone for the local watershed. Interpretive signage throughout the site provides information on the local flora and fauna species. It is a designated ZNIEFF area, recognized for its ecological importance in the Normandy region. The landscape changes significantly with seasonal water levels, which dictate bird migration patterns.
The elevated wooden viewing platforms located centrally within the marsh offer panoramic views of the reeds.
Bring binoculars as the boardwalks provide excellent vantage points for birdwatching.
Apply insect repellent during warmer months due to the wetland environment.
Keep to the designated wooden boardwalks to protect the fragile nesting grounds.
Do not attempt to traverse the marsh off-path, as the ground can be unstable and nesting sites are protected.
Stay on marked paths, keep dogs on a leash, and do not feed the local wildlife.
