(S/E) From the Olne Leisure Centre, head towards the village and then take the first path on the left called Chemin de Filpau. Once you have turned off, keep to the right (Trixhes or Tris) towards the Terwangne woods.
(1) On your left, pass the first white gate and follow the hedge for 100 metres before you see the second gate. From here, you will have a magnificent view towards Beaufays.
(2) Below, near an old farmhouse, you will find the third white gate, which you cross by turning left. You will see the fourth gate at the edge of the grove. As you cross it, you will see the fifth white gate straight ahead. Once you have crossed it, you will find yourself on the path called "La Vauxsale", which you follow downhill.
(3) At the bottom, in front of you, is the hamlet of Vaux-sous-Olne, which we will just touch on. After 150 metres, turn left and follow the stream (the resurgence of the Ri de Rode). Then turn left again onto the Soiron road (350 metres) towards a place called Tonvoie. Please note that the road is dangerous. Do not take the Tonvoie path, but continue along the road. After 50 metres, cross the Hazienne stream on your right and follow the path above it (the old access road to Soiron).
(4) You will arrive at the foot of Froidbermont (opposite you is the valley, classified as a protected area, up to a place called Les Fosses). Continue to the right and take the small path almost immediately on your right, which will lead you to the asphalt road of Croupet du Bois.
(5) Just before the summit, take the Haut Sart dirt track straight ahead. On the left, enjoy a beautiful view towards Olne and the Pays de Herve. Continue to the farm and take the asphalt path of Bois d'Olne on the left, which is a hairpin bend.
(6) After 200 metres, turn right onto the small path that will take you back to the Hazienne stream and the Soiron road. Cross it and take the path called En Egypte.
(7) At the top, turn left onto Chemin du Vieux Puits. You will now enter the hamlet of Froidbermont. On your left, you will see the old well, then you will arrive at Rue de Froidbermont. Follow this road downhill. After 150 metres, on the right, you will see the old Cense Seigneuriale de Froidbermont. Go around it to descend towards the Préhay pond with its pump.
(8) Facing the pond, go back up to Au Chêne via the asphalt path. Continue climbing towards Olne following the Filpau path. When you reach the village, turn right to return to the starting point, the Hall Omnisport (S/E).
