The Ecomaritime Park boardwalk in l’Anse du Port, Nicolet, Qc., Canada is now open. This elevated wooden boardwalk – 1km long, with a 12 m (39') high observatory at the end – was completely reconstructed. It crosses a sugar bush of silver maples and a marshland, which is home to a wide variety of fauna.
