Bayehon Walk - Mill and Waterfall

A pleasant walk that will take you to the Bayehon Waterfall, the second largest in Belgium. It is fed by the Hautes Fagnes springs, so its flow varies depending on the season. The route takes you through different types of vegetation, from deciduous trees to pines and the Fagne. Most of the route follows streams, which are crossed numerous times by small bridges.

Description of the walk

Departure from Moulin du Bayehon. The route is clockwise.

(S/E) Cross the small bridge to reach the path and turn left. Come out onto the main road at a hairpin bend.

(1) Cross the main road, stay to the right of the bridge and take the path on the left closest to the river. Shortly afterwards, cross the footbridge: this is the most difficult footbridge on the entire walk as it can be slippery. Continue to follow the Bayehon.

(2) Keep left at the intersection with the Ghâster.

(3) At thefourth wooden footbridge from the start, which is very small, cross over and climb up a fairly rocky path.

(4) At the top of the hill, you will be at the top of the waterfall in front of you. It is possible to go down, but the terrain is quite dangerous. Continue for about 30 metres, then turn right; go straight ahead and turn right at the T-junction.

(5) Follow the path on the left towards the kiosk without crossing the concrete bridge. Go around the kiosk on the right and follow the Bayehon river on a path where roots are visible. Be careful, this section is slippery.

(6) Continue straight ahead after the Old Oak Tree, then turn left along the forest. Follow this path straight ahead and further on, turn left at a 90° angle.

(7) Turn right. At the next junction, turn left and continue until you are close to the main road, about 60 metres away. Turn right at the hairpin bend to join it.

(8) Cross and walk carefully along the road on the right for 20 to 30 metres. Then continue the walk by taking the path on the left that runs alongside Pouhon until it intersects with the Bayehon.

(9) At this intersection overlooking a footbridge, turn left and cross the footbridge. Follow the path that runs alongside the Bayehon and crosses it several times to reach the mill (S/E).

Walking shoes recommended. Waterproofs in season.
Not really accessible for pushchairs or people with reduced mobility.
Some parts are muddy, even in summer.
No toilets along the route.

Duration: between 2 hours (very fast) and 3 hours (taking your time).

Worth a visit

At the end of the walk, enjoy the terraces of the Moulin du Bayehon (brasserie and light refreshments). Three indoor rooms and a wood fire in winter.

A beautiful route with plenty of variety and reasonable elevation changes.
However, we modified the route slightly between points 7 and 8 to take a small forest path that seems fairly new, along which we were able to admire some natural ephemeral works of art.

A very beautiful hike, mostly through woods and undergrowth, with a beautiful view of the Bayehon waterfall.
Arrival at the Bayehon mill where you can have a drink and something to eat, nice café.

As with all my walks, I use GPS throughout the walk. This means I never look at any signposts to guide me. It is therefore difficult for me to answer certain questions. This is also why I never send you descriptions of the walks I prepare for my walking group.
I make full use of the Visorando route (or my own) and follow it throughout the walk. It's very easy and reassuring.

A magnificent walk, just a little busy on the first part up to the waterfall.
Very beautiful and varied landscapes and not too difficult.

Nice walk. No problems with my two Belgian Malinois shepherds. Stunning waterfall 🤩. The crossings could be better explained.

Nice hike. A bit crowded at the waterfall, but otherwise not very busy overall. Nice discovery of the Moulin du Bayehon at the end of the hike.

We were lucky enough to do the snowy hike. It was pure bliss. To avoid the crowds, we set off on Saturday morning before 10 a.m. By 1 p.m., there were significantly more walkers. The Bayehon mill is also a wonderful discovery once you've completed the trail. We'll be back in May. Well done and thank you!

Easy to find and follow, it's a shame that the first few kilometres could have been nicer but they're currently cutting down trees and causing damage, and there were lots of mountain bikes on the first section on Sunday morning. Then it climbs for several kilometres but with a gentle gradient so you don't really notice it. The best part is the last section and especially the arrival at the waterfall, which is very pretty. The mill sells local produce and a wide selection of beers. Nice after a sunny hike.

You said the walk was easy... you should have mentioned that in snow and ice, it was much more difficult! It took us two hours to cover the first four kilometres!

A trail where the paths are sometimes narrow and filled with roots, making walking unpleasant. Nevertheless, it is very popular because the waterfall is a lovely destination for a walk. I therefore recommend this walk despite the difficulties over 2 or 3 kilometres. Otherwise, the region is superb and the natural surroundings beautiful.
