The birds of Grand-Voyeux

Description

After walking along the banks of the Thérouanne Canal, the Ourcq Canal and the Marne, continue your exploration at the edge of the Grand-Voyeux bird sanctuary, where dozens of species of birds live side by side.

This route is marked and signposted in yellow by Coderando 77.

1) Walk past the town hall and head towards the centre of the village. Cross the crossroads and continue straight ahead towards the Ourcq Canal.

2) Cross the canal, continue to the cemetery, then turn right and you will arrive at the Thérouannne Canal.

3) Take the towpath on the left. When you reach the Château du Gué-à-Tresmes, go up the small road on the left, then follow the road on the right for 500 metres.

4) Climb the path on the left, then turn left and descend into the undergrowth. Follow the Ourcq Canal on the right along the small balcony path (which corresponds to the upper boundary of the canal) for 1.5 km. Descend the slope on the right (caution) to pass under the canal via the aqueduct. At the exit, climb up to the left.

5) Take the towpath on the right for 800 m.

6) After a few small houses on the riverbank, find a small path on the right, cross the D 121 and descend towards the Marne. Follow the river on the left, then the branch that borders the Île de l'Ancre and pass the end of the Grand-Voyeux ornithological area.

7) Take the grassy path on the right and enter the Grand Voyeux bird sanctuary. Walk along the edge of the woods. Further on, turn sharply left, then right to reach the Grand Voyeux reserve house.

8) Turn left onto a small road, then pass in front of the church. Turn right onto Rue du Vert Moulin and take the small path on the left to cross the Thérouanne and reach the town hall.

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.
