In Corroy-le-Château: one of the most beautiful medieval castles in Belgium. In excellent condition. Private. Visits by appointment.
Basse Hollande, Large Eau and old lime kilns
When the sun and moon are out, the weather is usually ideal for hiking. This walk takes you on a journey of discovery through the Arton and Orneau valleys, starting from the Basse Hollande ponds in Corroy-le-Château.
The route passes successively through Les Trois Ponts, La Large Eau, the hamlet of Ferooz, the village of Bossière, as well as the old lime kilns and the Sainte-Barbe Chapel located along the Orneau north of the village of Mazy.
A tip for enthusiasts: in spring, the grassy descent between the plateau and the Orneau (between km 8 and 9) is covered with a magnificent carpet of wild garlic.

A superb mountain bike ride lasting around 1 hour 20 minutes, with stunning scenery all along the route. The route is pleasant, varied and, above all, very easy to follow, allowing you to enjoy the ride to the full without worrying about getting lost.
The route offers a wonderful immersion in nature, with leafy paths and peaceful spots that make the ride truly enjoyable from start to finish.
One small point to note, however — and this is obviously nobody’s fault — is that the section between point 7 and the finish is currently quite overgrown with nettles and a few brambles. You also need to be careful in this area, as there are four large burrows, probably occupied by badgers.
Despite this, this ride remains a wonderful experience that I’m happy to recommend to mountain bikers and nature lovers alike.

A lovely, very bucolic walk through woods, pastures and fields. Lots of trails, very little tarmac. It's a slight variation on the "Five villages south of Gembloux" walk in this app. Only the starting point is different, or almost. But it solves the problem of the private path on the other walk, as you don't go there. For dogs, there are lots of places where they can run free. My dog loved it, especially as some sections are very muddy at this time of year, she was in seventh heaven ;-)

Starting from the church on Rue Joseph Draye in Bothey, a village of 300 inhabitants in the municipality of Gembloux, set off to discover the rich heritage of the lower Orneau valley. Landscapes, churches, chapels and castles will delight you along this undulating route. Alternating wooded and rural passages. Along the roads, the grassy verges are generally flat and well maintained. There are numerous facilities where you can take a break during your walk.

As invigorating as can be in strong winds, this circular walk takes place mainly in the countryside on the agricultural plain between Gembloux, Jemeppe-sur-Sambre, Chastre and Sombreffe, bypassing the Docq crossroads (N29 x N93).In our opinion, it is more interesting on the north side than on the south side.You will discover some beautiful isolated trees, some magnificent rows of trees, a few merry-go-rounds, the strange Donjon de Villeret, the (deconsecrated) Église des Alouettes in the middle of nowhere, the Château d'eau de Sombreffe and a park of modern windmills (= wind turbines).

This short walk in the Bois Grand-Père takes you on a discovery of the hilly part of the Orneau valley to the south-west of the Grand-Manil district. There are no particular difficulties, except for a little mud on the path in the woods and between the Ferme de Bedauwe and the Orneau.The perfect family walk, alternating between trails, paved paths, countryside and forest.

Without entering them, discover five villages in the Gembloux area. This well-maintained route of around 15 km gives pride of place to paths and trails. In addition, 20% of the route is along roads with often flat and passable verges. In spring, the undergrowth is ablaze with flowers. On the hills, take a look around you: the landscapes will surprise you.

Starting from Spy Church, overlooking the square of the same name, the route leads to the small village of Onoz through fields, which can be seen at the bottom of a wooded valley along the Orneau. From there, shaded paths follow the banks of the stream and then explore the Bois de la Veuve and Bois du Bètch-aus-Rotches woods, located on the side of the valley. The route inevitably passes by the Spy Man's cave and the museum dedicated to him.
