Short circular in the Semoy valley
Set in lush green surroundings, this is an easy little route, ideal for getting back into exercise after a period of inactivity.
La Roche à Sept Heures
With a fairly challenging first section through the forest and a more leisurely second section along the Meuse and Semoy rivers, this route has two main destinations:
- the Roc la Tour site, a vast quartzite massif,
- and La Roche à Sept Heures, located at the top of rocky spurs overlooking the Meuse.
The viewpoint at this site offers a very picturesque panorama of the meander, considered to be the most spectacular in France, on the convex side of which Monthermé was built.
From one height to another around Thilay
This hike offers a variety of routes, allowing you to visit Roc la Tour and perhaps even meet the Ladies of Semoy. Changes to the route between (9) and (11) made on 27/7/2025 due to the closure of the Naux footbridge.
The Big Oak from Thilay
A short, mainly woodland route around Thilay and Naux. You will discover the old Moulin de la Gire mill, the former hamlet of Narbruay, and the Maison du Père Labranche. This walk also includes two viewpoints over Nohan, on the ridge of the Château de Linchamps.
Champ Bernard at the start of Thilay
After warming up on the Transsemoysienne, you will walk along the Gire stream and the Chaufour and Nantanru paths to reach the Champ Bernard clearing. You will return via Nohan, then along the left bank of the Semoy.
This hike offers two viewpoints over the Semoy valley.
Le Roc la Tour in the Château-Regnault Forest
For those who enjoy forests and elevation changes, and at the heart of the walk, the Roc la Tour is characterised by its quartzite columns, likely remnants of the Château du Diable. Here, you can enjoy a magnificent view of the Ardennes forest.
Roc la Tour from Thilay
This hike will take you along forest paths to a spectacular geological site hidden in the heart of the Château-Regnault National Forest.
East of Navaux
A forest trail starting from a small village in the Semoy Valley. La Roche au Pihü, Les Dames de Semoy and the Robessart viewpoint offer magnificent views of the valley's relief.
From Roc la Tour to Tchar Scaille
Forest route starting from Roc la Tour to the Six Chênons clearing.
Alternating between marked paths and more secluded trails.
Champ Bernard and the Nantanru Valley
Good physical condition is required for this short route, which has a significant elevation gain in its first section. The descent along the Ruisseau du Nantanru is very pretty and presents no difficulty. The return via the Transsemoisienne, the old "little train" route, allows for a leisurely return along the Semoy.
Col du Loup and Bois des Hazelles
Hike with no significant elevation gain, suitable for inexperienced walkers. Route mainly on forest trails. Beautiful views of the Semoy and the entrance to Hautes Rivières, at the Robertsart site, at the paragliding launch site.
Moderator's note : it seems that private property shortly afterwards (12) makes it necessary to return via the D13, see reviews.
From Les Hauts du Terne to Les Hauts Buttés
This hike will take you in the footsteps of the Cerceaux quarry workers and the inhabitants of the "Hauts" who once lived off livestock farming, crop cultivation and forestry. You can stroll along these varied paths, perhaps once trodden by pilgrims from Saint-Antoine des Hauts Buttés. On the way back, you will enjoy an easy descent along the Pilette stream.
La Roche à Sept Heures in Monthermé
A lovely walk for the whole family. Numerous viewpoints over the Meuse and a wide variety of landscapes.Early spring is the perfect time to enjoy a clearer view of the Monthermé loop. We were inspired by the guidebook "Les Ardennes à pieds" for this hike.
The Meuse ridges at Monthermé
From the river port, climb the Ardennes ridges overlooking Monthermé and Bogny-sur-Meuse. Pass by the viewpoints of La Roche à Sept Heures, La Roche Bayard, Les Quatre Frères Aymon and La Roche aux Sept Villages.
_++_Warning_++_: Very important
in case of rain or frost, the passage between points (7) and (8) may be difficult for novices

Around Linchamps
There is a lot of forest and surprising terrain around this long village on the right bank of the Saint-Jean stream.
On either side of the Ruisseau de l'Ours
Forest hike starting from Linchamps in the Hautes Rivières commune. A mountainous start, a passage through La Neuville aux Haies, a forest path overlooking the Ravin de l'Ours, a steep descent to find... the bear, and a peaceful finish.
