No signposts

Once back at the foot of the viewpoint, descend behind it. At the bottom, turn left and halfway down, look for a crossroads with a path.

Bike signposting: Red triangle on two red circles

Turn right. At the next intersection, turn left. At the fork, continue right for 1.2 km until the path turns right.

Without signposts

(2) Take the path opposite. At the fork (not shown on the maps), turn left. Enjoy the view of Cordemois Abbey. Go down the steps carved into the rock and continue along the path on the left. Enjoy the view from L'Épine. Continue down the path, which is now winding, until you reach the road.

(3) Continue to the left. A road will come back up on your right; continue straight ahead towards the suspension bridge. At Moulin de l'Épine, go down the path blocked by rocks to the footbridge. Cross the Semois via the suspension bridge. On the other side, walk straight ahead to the Moulin de l'Épine ford.

Turn left and walk for 220 m until you reach the crossroads at Broco.

(4) Turn left towards Rocher du Pendu. Follow the Semois. Pass the Abbaye de Cordemois, which is on the other side of the river. At the rocky slabs extending into the water (depending on the height of the Semois), climb up to the right. Further on, cross the concrete slab used as a bridge over the Ruisseau des Curnais.

(5) Turn right immediately. Climb the winding path to the Rocher du Pendu viewpoint. Turn your back to the viewpoint and continue along the path. At the fork, take the left path towards Bouillon. Descend the winding path to the bottom, but stop before you reach the Semois.

(10) Turn right. At the fork, continue left. Pass the Arboretum Géographique and continue along the path until you reach a fork. Continue left. When you reach the sign for the Arboretum Botanique plots (the signpost is on the ground), take the path on the left. At the fork (not shown on the maps), continue left. A path will then come back on your left; continue along it. At the wide path, continue right and go uphill.

(11) At the road, turn left and immediately left again onto the path. Back down on the road, continue left. Take the concrete path on your left until you reach the houses. Take the path that becomes a trail with a sign prohibiting motorised vehicles. Climb up and walk to the La Ramonette viewpoint and its shelter.

(12) Set off again on the path descending to the left of the shelter. Pass several viewpoints with benches overlooking Bouillon and its castle. At the intersection, take the path opposite to reach the last viewpoint of the castle. Back at the intersection, continue down the path. At the road, continue to the right, follow the Semois river and continue straight ahead at the junction to return to the Cordemoy Bridge and the car park (S/E).

Thank you for highlighting this very interesting route, which allows visitors to continue from the Moulin de l'Epine footbridge along several different trails: "Tombeau du Géant" (the Giant's Tomb), Corbion, the Semois via the Pendu rock, and on to Bouillon. The circuit is both quite physical (climbing the Auclun hill and descending or ascending to or from the Moulin de l'Epine footbridge) and peaceful once you are on the hill through the forest. It is beautiful and quiet. Few hikers are encountered, which is an advantage. There is a beautiful view from the belvedere over Bouillon and shortly before the descent to the footbridge over Clairefontaine Abbey.

Nice hike, the elevation gain isn't very significant but the climbs are sometimes a bit steep.

Very beautiful route, quite physically demanding, beautiful views, few people on the circuit, 5 to 6 people in total.
We set off at 10:05 a.m. and arrived 3½ hours later. Highly recommended.

A beautiful route, not very busy at the beginning of spring. The only problem we encountered was quad bikes between points 9 and 10 (are they allowed?). At point 10, we descended towards the Semois to return to Bouillon along the riverbank (crossing the campsite, which is currently being converted into a tourist development).

A very beautiful hike in glorious sunshine, with varied landscapes.
The hike was a bit challenging but very enjoyable.
The second part was less crowded, but the end offered a magnificent view of Bouillon Castle

Hiking under a bright sun, varied with a succession of ascents and descents and different landscapes (forests...), punctuated by beautiful views. A good time.

Be careful not to do this route after heavy rain, as the footbridge over the Semois river becomes inaccessible due to the rising water level. There is no alternative route, so you will have to turn back.

Thanks for confirming, Lenam96.

Walking along the main road is never pleasant.
The GR takes you there if there's flooding, but that's the alternative I'd like to avoid.
For the moment, I don't have a solution yet.

Best regards

Hello
We did the walk yesterday, and I can confirm that it is definitely the Pirôye stream, as there is nothing on the side of the stream crossing the bend. We cut across upstream, arriving on the main road, and took the path on the right in the bend of the N, after crossing the Pirôye stream.
So I don't know if the path is passable after point 9, it may have been due to bad weather...
In any case, it is possible to take the main road because there is grass along the side, but it's not very pleasant!
Otherwise, the walk was magnificent and fantastic throughout, a big thank you!

Hello,
It's after point 9, where the stream crosses the path (and has therefore turned into a lake...).

Hello Alain Bourgery,

thank you for the information.
Could you give me more details about the exact location?
Is it at the Pirôye stream near (9)?
or is it the stream that crosses the bend (only visible on IGN) before (10)?

That would be a great help in figuring out where to scout an alternative route.

Thank you

Hello,
I wanted to do this tempting hike on Wednesday and everything went well until I came to a stream crossing the path because... the stream had been turned into a lake by our friends the beavers, and they hadn't planned a detour! I had to turn back after a few attempts to get around it ;<(
So plan to go around the stream upstream between points 9 and 10.

Hello sapeurmomo,
A slight change to the hike... it's the Poupehan hike that has the ladders along the route.
