Grand-Voyeux Regional Nature Reserve

As if it were the Baie de Somme...
Its 241 hectares, 60% of which are covered by water, offer visitors a patchwork of amazing landscapes located in the immediate vicinity of the Marne: ponds, reed beds, meadows and groves provide shelter and food for more than 225 species of birds, some of which are endangered in the region, and which are undoubtedly the most remarkable wealth of the reserve ...

Exceptional for the fauna and flora it shelters, it is part of the Natura 2000 site "Les Boucles de la Marne".

Not so long ago, the Grand-Voyeux Regional Nature Reserve was still a quarry, where conveyors extracted sand and gravel with a crunch of grains. Excavated in the 1970s, the cavities were gradually transformed into waterholes, quickly colonised by reeds and birds, thus allowing nature to take over.

The Maison du Grand-Voyeux is open to the public two days a week, with the aim of helping visitors discover the Grand-Voyeux while preserving biodiversity and the balance of the ecosystems.
A discovery trail and observatories allow visitors to discover the incredible landscapes of the site and the multitude of bird species that have found refuge there. Nature activities, workshops and thematic conferences are also organised regularly and free of charge (see programme online at www.maisondugrandvoyeux.fr).

Managed by the Agence des espaces verts (AEV) of the Île-de-France Region since 1999, it was classified as a Regional Nature Reserve in 2012. A partner of the AEV, the Association pour la Valorisation des Espaces Naturels du Grand Voyeux is responsible for the scientific monitoring of the site and for certain activities.
