La Vanne (rivière) walks

From Chigy (Les Vallées de la Vanne) to Pont-sur-Vanne, this trail passes through natural sites included in the European Natura 2000 network, which recognises the richness of their flora and fauna. The dry grasslands on chalk offer significant and unique floral diversity. The view over the Vanne valley is breathtaking. Information boards along the route explain the site’s natural riches.
