Ignore the path on the embankment leading back to your right and continue straight on until you reach the road.

(6) Turn right and walk carefully along the busy road until you reach the beautifully landscaped car park on your left. Turn right onto the path opposite the car park and near the meadow. Keep to the left of the rock and, at the fork, keep left. Climb up and pass the Mergire Viewpoint. Continue to the Chapel of Notre-Dame du Prompt Secours.

(7) Opposite the chapel entrance, take the path to the right of it. You’ll come to a dirt track; continue straight ahead. At the bend, carry on straight along the path.

Walk along the road carefully and head towards thesecond barrier on the right, set back from the road. Go through the barrier, close it behind you and walk to the tunnel.

(11) Go through the tunnel, pass the gate and head up the path, keeping to your left. You’ll come to a schist picnic table on your right and the first ‘Talking Stone’ on your left; turn right into the broom. Further on, pass the gate, ignore the hairpin bend to the right and continue to the crossroads.

(12) Turn left onto the path, which has a road sign (White Circle with a Red Circle) at the entrance prohibiting motorbikes and cars. Go through the barrier and walk for about 800 m, ignoring the paths on your left. At the schist picnic table, take the path on the left. Follow it for a short while and, once back on the wide path, continue to the left. Walk to the Talking Stone at Sainte-Barbe Chapel (visible below, depending on the foliage).

(13) Turn back and look for the path on your right, climbing up the embankment, before the large fir tree. The blue ‘i’ sign on a slender birch trunk confirms this.

A lovely walk; thankfully, the tarmac sections are short. One slight downside: the route gets a bit monotonous between points 12 and 13. I particularly loved the old cemetery in Mortehan and the Semois in bloom.

A superb route with a variety of paths (wide forest trails, ridges, waterside paths) .
It's a shame that some of the picnic areas are not maintained (but this is not Visorando's responsibility ).

A magnificent hike under the March sunshine.
We enjoyed the paths, trails and some lovely views of the Semois and its surroundings.
An easy walk overall, but with a few small hills that are challenging but not insurmountable.
What a joy to walk in nature, despite two places where inconsiderate people throw their rubbish next to bins or even throw their rubbish bags, old slides and so on in the middle of the forest. It's very sad
But this is really a lovely outing that you should definitely do.

A beautiful route without any difficulties and without necessarily many viewpoints.

Be careful at waypoint 13, as the blue markings are difficult to see due to the vegetation.

A very beautiful walk that can be described as moderately difficult, but not too much so. We went from one surprise to another: the fairy castle, views of Cugnon, rocks and ridges,

Good evening, Carla,
Oops, yes, it is point 16.
But no matter, I covered a bit more distance and elevation.
In any case, it was a very nice hike, and now I'm sitting with my feet up watching football...
Have a lovely evening, and see you soon, who knows, maybe at the crossroads.
Kind regards.
Bernard

Hello Bernard,

the path to take at (13) isn't very wide, and you have to be careful to spot it
but without the foliage, it should have been easier.
By taking this path, I saved myself a bit of a climb
There is no point (17) ... but I understand the inconvenience, it's not pleasant to have to step over large ruts
The day must have been lovely with such beautiful sunshine

Looking forward to seeing you again
Have a good hike

Hello,
A beautiful afternoon in the sunshine with stunning surroundings.
At point 13, which wasn't obvious, I went a little further to the sign, turned left, went downhill, crossed the road and went back up the other side (an extra 450 metres).
From point 17 to the finish, it was a logging road (ruts, mud)... not the organiser's fault, but the loggers'...
A really beautiful walk, and I would also say borderline difficult, but doable.
Many thanks.

A really beautiful hike because it's so varied 🤩 I loved everything about it
Moderate to difficult difficulty 💪
A bit lost at point 13, but I like that 🙃
It's quite a climb on the way back, so save your energy 😀
Thank you 🦵
