Description of the walk

Starting point: Arboretum du Bois de la Vierge, accessible from Vendresse via a road suitable for vehicles (1.5 km)

(S/E) Take the arboretum path and follow the signs (white arrows). After two paths, you will reach the Ligne aux Sapins (east-west direction) at the north-east corner of forest plot no. 15.

(1) Take this magnificent avenue on the right to its eastern end.

(2) Continue in the same direction until you reach a crossroads with six paths.

(3) Take the second path on the left (the one that climbs the most) and reach the boundary between the municipalities of Omicourt and Vendresse, marked by a ditch.

(4) Turn left and follow this boundary. At the next crossroads, turn right up a private road that branches off to the left towards Mont Joly.

(5) Do not take the path on the left, but continue north-east on a wide stone path that leads to Omicourt.

(6) Turn onto Rue du Chaud and immediately turn left onto Rue des Chayères, then take a small path heading north to join a forest road.

(7) Turn left onto the forest road to reach a crossroads on the ridge between the Bar and Rouge Cogneux valleys.

(8) Take the middle path, which descends towards the Hannognes path in Saint-Aignan.

(9) Take the leftmost path to climb up the Rouge Cogneux valley to its source.

(10) Continue in the same direction until you reach the boundary between the two parishes, which you have already crossed.

(11) Follow the boundary between the two municipalities on the left, which runs alongside a private plot of land, until you reach the edge of the Vendresse National Forest.

(12) Turn right before forest plot No. 1 until you reach the first path on the left, which marks the boundary between plots No. 1 and No. 2.

(13) Follow this plot boundary. It soon joins a more clearly marked path. Turn left to join the Route Forestière de la Vierge.

(14) Stay on this road until you reach the line of fir trees. Turn right, then left to finish at the end of the arboretum route (S/E).

A magnificent and majestic spot (arboretum), with a beautiful view over the Bar Valley from the top of Omicourt; peaceful and quiet, with the intriguing Cogneux spring; a route that’s fairly easy to follow on a map and with GPS. A lovely discovery – thank you

A pleasant walk in the cool shade of the woods, ideal on a hot day. The first part is the most beautiful and informative (the arboretum). There are few views of the surrounding area as it is almost entirely in the woods. Lots of birds, complete peace and quiet as we didn't see a single hiker, a beautiful variety of tree species, including some magnificent specimens of Douglas fir and oak.
PS: Be careful: there are grassy areas and branches on the path, and we came back with ticks...

Very beautiful route, except that the paths are not maintained and the source is not marked any better than that.

Superb hike under glorious sunshine... Well-marked route. A few trees had been blown down by recent storms along the route, but this posed no difficulty. Pure pleasure in the midst of nature ready to awaken: Done solo with my dog. No difficulty. We finished with a walk around Lake Bairon a few kilometres away: Sublime!!!! whistle:!!!!

Thank you for suggesting this hike.

A very beautiful hike in the Ardennes, even in the heatwave. Beautiful landscapes of undergrowth and valleys. The source of the Rouge Cogneux is very refreshing for your shoes. A small note: stay on the path (stream on the right) between 9 and 10, there is a ford, but the vegetation is very dense there (bring a pruning knife).
Thank you for this beautiful walk. We recommend it.

A very beautiful walk in the woods. I suggest an alternative route: from point 5 in Omicourt, follow the canal towards Saint-Aignan, go through the tunnel that crosses the canal, then, at the tunnel exit, immediately take the small road on the left to reach point 8.
