Places along the river
Departments and towns along the river include:
Small boats can travel much of the length of the river. Canals join the Aisne to the Seine and Meuse rivers. In the small-capacity network of waterways, the Aisne and the Canal latéral à l'Aisne (Aisne lateral canal) give access to the agricultural towns of Soissons and Vailly-sur-Aisne, both large exporters of cereals. The waterway also links Northwestern Europe to the small inland harbour of Reims, where metallurgical industries depend on inland waterways transport. The Aisne is connected to the rest of the network by the Oise, the Canal de l'Oise à l'Aisne the Canal des Ardennes and the Canal de l'Aisne à la Marne. (Source: NoorderSoft Waterways Database)
