Departure from the main square in Bioul, opposite the driveway to Bioul Castle.
(S/E) Take the large tree-lined driveway and continue to the porch to admire the magnificent inner courtyard of the château (private property and wine estate). If possible, visit the grounds and park.
(1) Retrace your steps and take Rue de Fraire westwards.
(2) At the three-way junction, take Rue Frisles to the right, then 20 metres further on, turn left into Rue Grand Tilleul.
(3) Take Chemin du Bois Petit Jean to the right, leaving Grand Chemin de Graux on your left.
Opposite the pavilion on the left at the edge of the woods, about 250 metres. The path on the right leads into the private grounds of Château de Neffe.
A majestic beech tree-lined avenue is well worth a short detour of a few hundred metres along this path... Do not go past the gate at the entrance to the château grounds, unless you have special permission (Heritage Days, organised walks, etc.).
(4) Turn left and go up the country lane. The view soon opens up on the other side.
(5) Do not enter the forest. Turn right. Go up the path (sometimes muddy in rainy weather) and cross the road (watch out for traffic). Go straight down the path, which turns into a trail, to the chapel.
(6) Beautiful view of the rear of the former Brogne Abbey in Saint-Gérard and the old tannery in the valley. Take the path on the left that runs alongside a wood, fields and then meadows.
(7) Turn right and join Grand-Rue. Follow Grand-Rue to the right until you reach the chapel.
(8) Turn left and follow the grassy path, leaving Rue de la Chapelle to curve and climb to the right.
(9) At the T-junction, follow Rue du Parc to the right. At the crossroads, there is a tree and a signpost saying "No motorcycles". Let Rue du Parc turn right. Take the path on the left and immediately turn right to walk along the Château Saint-Roch property, whose rear façade and magnificent grounds can be seen on the right through the hedge. When you reach the road, turn right.
(10) Take the grassy path down to the left just after an isolated house.
Turn right and cross the road (watch out for traffic).
(11) At the edge of the woods, take the path that climbs to the right and quickly leads to the edge of the fields. Beautiful view of Saint-Gérard on the right.
(12) Turn right after the woods and follow the path down to the road. Cross the road (mind the traffic). At the calvary, turn right.
(13) Turn left and head along Rue de Montigny towards the farms of the same name and the Chapel of Notre-Dame de La Salette.
(14) Just before the farms, take the path to the right. Pass the Château de Neffe farm.
When you reach the pond on the Le Burnot stream, turn three-quarters of the way to the right and admire one of the turrets of Château de Neffe, visible through the gap.
(15) Turn right onto Chemin de Saint-Gérard and walk across the meadows to the top.
(16) After the first property on Rue Frisles, turn onto the grassy path/trail that descends to the left towards the cemetery.
A few vines on the left, just before the cemetery. Turn left to return to your starting point (S/E).
