(S/E) Let's start from the kiosk next to the sports hall and take the alley opposite the school to reach the village centre. Admire the Church of Saint Sebastian and the old houses on Rue Village with their potales. Descend to the right of the Maison Communale (former patrician house dating from 1742) to cross its garden and head towards the Ri de Rode. On the right, at No. 6 Rue du Chantoir, you can see the old brewery.
(1) Turn your back on the brewery and take the small path to the left of the farm's entrance gate. This narrow path is often quite muddy because a spring emerges from the ground a little further on. As you climb, you will see Olne Castle on your right. Continue to follow signpost no. 1, which will take you to Pré des Paul, Chemin de la Justice and Martinmont. Be sure to take a look at the local stone farms (limestone and sandstone).
(2) Follow the asphalt path from Martinmont (walk no. 1) for 150 metres before turning left. Soon you will find yourself in the heart of the bocage, where a series of footbridges show you the way.
(3) At the edge of the meadows (after the white footbridge), take the path on the right towards Rafhay, which you cross to reach the monument in memory of Sergeant Adams. Continue along this path (Rue Pont Al Planche) to the woods on the left.
(4) The arrows for walk no. 1 indicate the small shaded path on the left, which you should follow through the woods. Be careful, the first few metres can be slippery! At the edge of the woods, you will arrive at Rue Gérardheid and then Rue Saint Hadelin. Walk up this street for about a hundred metres until you reach the junction with Chemin du Rouau. As you cross Saint-Hadelin, admire the limestone houses, which are often decorated with potales, ancient inscriptions and dates.
(5) Before taking Chemin du Rouau and continuing on marked route no. 1, it is well worth making a short detour to the place known as "Le Fief" (100 metres away on the other side of Rue St Hadelin). Here you will see the Ancion house, an 18th-century gem, the Saint Hadelin church, the nail tree and a pretty viewpoint. We then return to Rue du Rouau and Rue "Au château de Saint Hadelin" (part of the old Voie de Liège), which we follow to the "Vieux Tilleul" (old lime tree). A branch from this tree has been turned into a sculpture in front of the Hall Omnisports. Further on, we can see the first houses of the village.
(6) Turn left, following the signs for walk no. 1. You will be treated to a beautiful view of the village of Olne. Continue along the Herdavoie road towards the village centre. The old buildings of the village come into view, with a calvary and war memorial in the foreground. Continue straight on to the main street that crosses Olne with its large gates topped with "teutés".
(7) Take Ruelle de l'Arvô, located just opposite the village hall. We arrive at Rue des Combattants with its large 18th-century buildings. Leave the church on your left and go up Rue Froidbermont to the first road on the left, which leads to the car park of the Hall Omnisports, in front of which is a sculpture made from a large branch torn from the "Vieux Tilleul" (old lime tree) in 2013, which you saw during the walk (S/E).
