River Les

The Les River is a Belgian river with a length of 89 kilometers, which carries its waters into the Meuse River. The river flows mainly to the northwest and also has an underground stretch of 1,100 meters in the caves of An, near the village of An-sur-Les. The water level in the river has significant differences at the source and mouth, its maximum depth does not exceed one and a half meters. Most of the forest flows in the country’s highlands.

The coast of the non-navigable river attracts tourists with beautiful nature with forests, cliffs and rocks, on one of which stands the castle of Valsen. On the last 20 kilometers of the river it is very convenient to swim by canoe or kayak.
