Located in the heart of the Somme valley, the Belloy-sur-Somme marsh constitutes a preserved area of nearly 90 hectares with high ecological value. The diversity and quality of the present environments allow for the expression of fauna and flora characteristic of alkaline peat bogs. A path punctuated by educational signs allows you to cross the marsh and thus discover the different environments that make it up: ponds, peat rafts, reed beds, humid woodlands. www.cen-hautsdefrance.org/site/le-marais-de-belloy-sur-somme/
