The route runs along the water's edge, passing several viewpoints, including the confluence of the two Ourthes rivers. The Nisramont dam and two footbridges are essential for crossing from one bank to the other.
Please note: this is a challenging hike (see practical information)

Description of the walk

Parking at the church in Engreux.

(S/E) Opposite the church, take the road on the right and go down to the fork.

(1) Turn left. The road becomes concrete slabs and ends in dirt. Take the forest path straight ahead. Pass through Fagnoule, continue downhill and turn right at the next intersection. This wide path will become a narrower path leading down to the banks of the Ourthe. Then turn right until you reach the footbridge.

(2) Cross over and turn left on the other side.

^GR® signposting(red and white).

Follow the water for a while and then climb up to the Deux Ourthes viewpoint. Do not take any paths other than the main one, the GR^®.

(3) Take the path behind the viewpoint and head towards the Laid Tier viewpoint.

(4) Turn left and follow the ridge trail to the Au Fays viewpoint.

(5) Continue along the path, which becomes a staircase. This will take you to the Nisramont dam crossing.

(6) Go over the dam and turn left.

Red diamond signpost

Follow the Ourthe, ignoring the paths on your right, until you reach the Kwaï bridge.

(7) Cross the bridge and begin the winding climb to the shelter.

(8) Continue along the trail, following the red diamond markings and ignoring all the trails on your right, until you reach the^second footbridge.

(9) Cross the footbridge and turn left. After 150 metres, leave the signposts and start climbing the forest path on the right. Ignore the path on the left towards ADEPS (sports centre). The forest path becomes a road, which you follow. Pass the chapel and continue straight ahead until you finally reach the church (S/E).

Notes

Although rated as moderate, this hike is demanding due to its many ascents and descents. Do not underestimate yourself. Look carefully at the graph on a PC or horizontally on a smartphone to get an idea of the terrain. The elevation gain is 346 m.

You can get refreshments at the start/finish and at the foot of the Nisramont Dam.
The trails are muddy in places.
Some sections have steps, bridges and ramps.
Benches are available near the church, at Laid Tier, and at the water's edge on the first kilometre of the return trail after the dam.
Shelter at the following points: (3) and (8)
From October to December, please be aware of hunting dates

Worth a visit

During

Viewpoints: at Deux Ourthes, Laid Tier, Fays and on the opposite bank above the Kwaï bridge.
Fish ladders: near the footbridges (pre-dam), these allow fish to cross a man-made obstacle on a watercourse, such as a dam or a weir. They consist of a series of pools separated by short drops, which the fish can cross one at a time. Each basin is designed to create a recirculation zone with low flow velocities where fish can rest. The main difficulty in installing a fish ladder is to "capture" the fish downstream of it by creating an area of intense, highly oxygenated current that will guide them to the foot of the ladder.

Nisramont dam: 116 m long and 16 m high. Swimming is prohibited as it was built to supply drinking water to the entire region.

Very beautiful hike, as described: ~15km, quite physically demanding with a few technical sections.
A bit busy but still very reasonable.

Hello everyone,
A really enjoyable hike of over 15 km (not 13 as indicated). However, in the snow, it's a whole different ball game. You really need to take this into account. Some sections are technical and very slippery in the snow. Make sure you're well equipped for the cold.
There is some very interesting wildlife to see, including lots of birds and beavers.

Hello 23091950,

There may be some confusion about the hike, as you mention the Semois, but here it is the Ourthe that takes centre stage. Western and eastern, but no Semois.
With all the rain we've had over the last few days, all the hikes near rivers are tricky.

Hello,

this hike is best done in summer, as the paths are very wet, the Semois river is very high, and there are some particularly
tricky, difficult to keep your feet dry

@lemarcheur65 when a profile is private, which is the case for Vincentvince67, we are unable to send private messages. Only moderators have this ability.
However, I contacted him via his email address and found an unedited record of the GPS errors that caused 19 km to be recorded.

Have a nice day.

Hello Madam, thank you for your reply.
I took the liberty of posting the photos (print screens) from both the VISIORANO app (which shows part of the route; I take print screens to show my progress to my wife) and my SAMSUNG HEALTH app: the photo of the route and the main data. I hope the moderators will accept them.
If not, I can send you my email address: molle.vincent.vince@gmail.com, where you can write to me and I will send you the photos if the moderators refuse them (there are only three).
You will see that the routes are similar (I may have made one or two U-turns of a few metres, but that's all), and, in the other photo, that the distance of 19 km is confirmed.

I followed the markers all the way to the end.

Thank you also for your comment on the difficulty level and for trying to pass the information on to the moderators. As I mentioned, I did the forests around Montleban (which are also available on Visorando), which were used as the average for the difficulty level... Honestly, the two hikes are incomparable in terms of difficulty.

To end on a positive note, I will still post a few photos I took.

Have a great day and thank you for your responsiveness.

Vincent

Hello Vincentvince67,

i'm very surprised by the mileage you've reported!
My husband just drove the same route last Sunday and got the same mileage.
Did you use a different app?
As your profile is private, I can't see your route to understand where the problem lies.
Did you start from the same place? Did you perhaps make a mistake and turn back? The complete route marked with red diamonds is 14 km long, but my route is shorter than what they suggest.
Did you take the wrong route?

The difficulty level is assessed by Visorando, which looks at the elevation gain and the number of kilometres. Given the number of comments about the assessment, I asked a moderator if I could change it to difficult or, at the very least, add "demanding hike" to the introduction. It's mainly a question of physical condition and perception.

Best regards

I agree with the previous comment: THIS ROUTE IS 19.41 KM LONG, not 13.86 km as stated in the description. This really needs to be corrected for people who are choosing their route based on the length.
Furthermore, having done a route classified as moderate the day before (the Montleban forests), I can also confirm that the Ourthes route cannot be classified as moderate either. It is difficult, much more difficult:

1. due to the effort required, not only in terms of length, but also for certain sections, which are difficult (I strongly advise against this route for beginners, and forget about doing it with children, it would be downright irresponsible).

2. some sections are very uneven; the final section is a real challenge; here too, as previously mentioned, the last part is on a relatively steep slope

3. some sections are very steep, with a real risk of falling.

In the end, I agree with several reviews that describe this hike as magnificent, because it is true that the landscapes are relatively varied, and some of the views of the Ourthe are magnificent.

But I was very disappointed compared to the description: the length (VERY inaccurate) and the level of difficulty make the last 5 kilometres a real challenge, during which you mainly think about finishing and not falling over, rather than enjoying the scenery. As much as I enjoyed my two other hikes (Limerlé/Steinbach and Montleban), I would never have considered doing this one if I had known how long and difficult it was.

The positive thing is that getting to the end allowed me to push my limits... but at what cost!

A very beautiful route with many challenges but magnificent scenery. The only downside was the end of the route, with a 2 km climb back to the car
