AzureNestled in the hollow of a valley, this small circuit allows you to discover a strange device: at this point the canal from the Oise to the Aisne rushes into a tunnel 2,365 m long, linking the valley of the Aisne to that of the Ailette. To understand how it works, do not hesitate to consult the interpretation panel located in Braye-en-Laonnois.
