Before you set off on a trip of any kind, the Liege Port Authority urges you to consult the opinions of the water transport sector("Les Avis à la Batellerie" ) published every month by the Ministry of Infrastructure and Transport, DG.2 Directorate-General for Waterways.
These opinions may be consulted directly on the Directorate-General for Waterways' Internet site:
The Walloon inland waterways network covers 451km, 81% at least of which is European class IV gauge, i.e. up to 1,350 tonnes.
The network manager, the Ministry of Infrastructure and Transport's Directorate-General for Waterways, has created a useful tool for viewing the details and various nautical restrictions on a route between two ports in the Walloon river network.
