Walk along the ridges via Vaux and the Bois d'Olne

This walk takes us to Petit Vaux and the entrance to Nessonvaux, where we climb the Bois-d'Olne hill on its southern slope. From Bois-d'Olne to Grihanster, we walk along a magnificent ridge. From here, we can admire two very different landscapes. To the north, the Hazienne valley and the village of Olne, and to the south, the Vesdre valley and the first wooded foothills of the Ardennes.

Description of the walk

Departure from the Olne Sports Centre (Leisure Centre).

Yellow rectangle markings (hike number 5).

(S/E) Head towards the village, towards Saint-Sébastien Church.

(1) Take thefirst path on the left, called Chemin de Filpau. As soon as you enter the path, keep to the right (Les Tris - Trixhes) towards the Bois de Terwangne. Further on, pass afirst white gate and follow a hedge for 100 metres before you see asecond one (magnificent view towards Beaufays). Continue and, below, at an old farmhouse, you will find thethird white gate, which you cross by turning left. You will see thefourth gate at the edge of the grove. Once you have crossed it, you will see thefifth white gate straight ahead. Once you have crossed it, you will find yourself on the path called "la Vauxsale", which you follow downhill.

(2) At the bottom of this descent, you will pass close to the hamlet of Vaux-sous-Olne. At the end of the road, turn left and follow the stream (the resurgence of the Ri de Rode). Cross the Soiron road and take the path on the left of the stream. Then cross the N604 and continue opposite towards the Petit-Vaux square.

(3) Cross the N604 again and take the path on the left that runs alongside the stream. After the second footbridge, continue straight ahead.

(4) At the end of the bend, take the steps directly on your left. You will see the Vesdre river as soon as you start climbing. As you continue to climb, note the old Imperia factory and the remains of the test track. At the top, turn right, cross several meadows and turn left. After 100 metres, turn right onto an asphalt road and continue for about 300 metres.

(5) Opposite an old manor house, turn right onto the path called Maison Bois. This will take you to a junction with Chemin Sol Crest: turn right and continue uphill.

(6) On the right, you can quickly reach a remarkable viewpoint over the meanders of the Vesdre. Retrace your steps.

(6) Continue eastwards to the top of the ridge.

(7) Then take thefirst path on the left. After about 100 metres, turn right onto the Haut Sart dirt track (on the left, beautiful view towards Olne and the Pays de Herve). Continue to the farm, then turn left onto the asphalt road called Bois d'Olne. After 100 metres, turn right onto a path that leads back to the Hazienne stream and the Route de Soiron. Cross this road and take the path called En Égypte.

(8) At the top, turn left onto Chemin du Vieux Puits and enter the hamlet of Froidbermont. On your left, admire the old well. When you reach Rue de Froidbermont, follow it downhill. After 150 m, you will see the old Cense Seigneuriale de Froidbermont on your right: go around it and descend towards the Étang de Préhay with its pump.

(9) Facing the pond, go up the paved path "Au Chêne". Continue uphill towards Olne, following Chemin Filpau.

(1) When you reach the village (church), turn right to return to the Hall Omnisport (S/E).

Worth a visit

Starting from Olne, one of the "Most Beautiful Villages in Wallonia", our walk takes us to Vaux-sous-Olne, where there are numerous traces of mills and watercourses. Magnificent views can be enjoyed from the ridge at Bois d'Olne. The return via Froidbermont takes us close to the "seigneurial farm".

If you would like to find out more about the heritage of Olne, please visit the website of the most beautiful villages in Wallonia, the website of the municipality of Olne and Wikipedia

Those interested in "small heritage" can consult this website, which provides explanations for each object (potales, crosses, drinking troughs, gateways with teutés, remarkable trees, etc.) and locates them on a map.

During the walk

Admire the Church of Saint-Remacle and its old cemetery, the 17th and 18th century houses built from rubble stone extracted from nearby quarries. Some houses are made of red brick with carved limestone bands. The town hall, dating from 1746, was originally a typical 18th century bourgeois house.
(3) The valleys of Vaux-sous-Olne and Nessonvaux are "mill valleys". Waterwheels provided the power initially used to grind wheat, then to work iron and finally to manufacture cannons and guns. As the waterwheels have disappeared (except for Moulin André), it is often the old watercourses that enable us to locate the former mills.
(9) Former "seigneurial farm" in the Mosan Renaissance style.

A bit muddy at first—but that's the season for it—the scenery is very pleasant and the walk is quite varied. Fields, river, woods... and very few roads.

In principle, a beautiful hike with a few minor drawbacks. In some places, the paths were so narrow that we were constantly getting caught on brambles. In Nessonvaux, the signposting was not ideal.

Hello Ayko
Reminder:

Visorando prefers to guide hikers using a description and an extract from an IGN map rather than signposting, which it has no control over. When completing this questionnaire, please focus your comments on the quality of the description and the route, without mentioning the signposting.

Are you sure? I did it last Thursday and everything seemed fine. I'll transfer it anyway for verification.

A very pretty and peaceful walk. The signposting is a real bonus (although you do need to keep your eyes peeled at times).

A word of caution, however, at stage 4: a fallen tree on a bend in the path makes it almost invisible, forcing you to take a very narrow path straight ahead, which can be dangerous as it is sometimes unstable and on a fairly steep hillside. If you see a fallen tree, turn towards it and step over it!

pS: don't be surprised to find yourself sharing the field with a herd of cows on the first stage; you are definitely on the right track

A very beautiful walk through lush green countryside. Particularly pleasant in the April sunshine. Some sections are quite strenuous and require a fair amount of stamina.

Very beautiful and pleasant route.
There is currently a small detour at the end of the route due to illness among the salamanders.
The detour is very well signposted and does not detract from the walk (except for a few extra steps...).
We encountered no more than fifteen people on the trail, on a bank holiday Monday with changeable weather.

Apart from the first 100 metres in real mud, it's a very beautiful and varied route. Sometimes slippery, but better than concrete. And what beautiful light on a beautiful winter's day...
It also has the advantage of being very well signposted (yellow rectangles), which is important. The route is very quiet, but that's to be expected on a Saturday morning.

A very beautiful walk. We did it in the rain, so there weren't many people around. The path was very muddy and slippery, but that's all part of the sport. The signposting was excellent.

A very pleasant and fairly easy walk with lovely views all along the route. The description on the website is excellent and accurate. At one point, we turned back because there were no signs in sight and we were unsure which of two paths to take, but otherwise it was very enjoyable and a very varied route with some hills and so on
