After Chassepierre, the Semois goes north to begin its entirely forest course, to the French border some 95 km further. A stop is recommended 2 km downstream from Chassepierre, "Conry" area (difficult access by car, Sainte-Cécile campsite, private) before a 10 km stage in the forest without a landing area._cc781905-5cde-3194-bb3b -136bad5cf58d_ The river follows its fun and easy course; 4.5 km downstream from the “Conry” rest area, the Vanne des Moines dam can be crossed carrying (cautious) or getting wet (sporty). To cross while sailing, take the pass arranged at the right end of the dam (about 2 meters from the shore, identification essential); it is the rightmost passage that is used, the left part of the passage, too steep, is not suitable (risk of capsizing and danger due to the concrete blocks at the bottom of the water). By portage, pass the boats over the rocks of the dam, rather on the left, with an easy release downstream on the gravel of a vague island. 

​

About 5 km after the Moines valve, two tight meanders lead to a first meadow, for a short distance, then after a few hundred meters, the forest opens on the left onto the park of the former Priory of Conques. Another meander and at the exit of it, an old dam must be crossed again: passage to be identified according to the water level, generally easier on the right. 150 meters downstream from the dam, on the right bank, “Champ le Monde” area (delicate docking, rocks, concrete blocks, branches, difficult manoeuvre, no parking). 

​

A kilometer further on, after the large railway bridge (now disused), the Moulin Willaime dam appears, with the campsite on the right. There is a passage between the large stones, undeveloped and narrow, located on the left side and relatively in the middle of the dam. Difficult to spot, this passage requires you to make a very tight turn to the right immediately after crossing it. The maneuver being difficult for beginners with a canoe or a two-seater kayak, it is often preferable to carry the boat on the dam (then choose to pass near the Mill, on the right of the dam).

​

About 300 m downstream from the dam, at the end of a meadow (private, access subject to authorization from the neighboring campsite), on the right bank, Moulin Willaime area (car access, small car park). The river then plunges into the forest for a long meander, forming the Tombeau du Chevalier. 6 km downstream from Moulin Willaime, the current calms down very clearly as it approaches Herbeumont beach (right bank). 

The Nawés dam (or Moulin Deleau) is crossed via a succession of passes on the left of the dam. Attention, presence of scrap metal on the sides of the passes and in the water: for boats that are not very maneuverable (canoe, two-seater kayak), pass preferably empty, guiding your boat with a rope. 

​

Downstream from Moulin Deleau, the Semois leads to Linglé, an area on the left bank, just upstream from the bridge (easy maneuvering and parking). From this point, the Semois becomes "navigable" or rather "floatable" within the meaning of the legislation on hydraulic routes, reminiscent of the history of places where agricultural and forestry production traveled on the river, in preference to forest roads. , isolated and difficult.
