Hiking in Wallonia: fortified castle and valley

  • Walking or hiking

The 9 km (3 hours) descent from the ‘Ferme de Montaigle’ towards Montaigle castle across the Flavion valley is especially worth a detour. Along the Flavion you can make out the steep rock walls of several caves where hunter-gatherers lived in the Stone Age.

The castle ruins and the Montaigle museum are unmissable. In addition, after the castle you’ll have a superb view over the fluvial landscape and the rocks all around. The return journey to Falaën crosses the hamlet of ‘Le Marteau’ in the Molignée valley and the bare heights of ‘La Héronnière’.

Route/Points of Interest

  • From the church (S), the signage (green/white/green) leads you on to the Rue du Château-ferme, which runs outside the village passing close to the château-farm.
  • After nearly 1km, you’ll see a chapel on your right (1). The little winding lane then heads towards Flun (2). Having passed through the hamlet, the lane crosses a stone bridge and then turns left into the wood.
  • The small forest track then follows the meandering river Flavion as far as a crossing with another lane (‘Les Hayettes’).
  • There, it climbs to the right to another crossing, where the waymarkers are again visible.
  • The route soon turns left on to the rue de Montaigle and continues straight ahead to the farm of the same name.
  • Behind the Montaigle farm (3), a path descends again into the Flavion valley. Then it follows the watercourse and crosses an ancient landscape of limestone and gentle meadows.
  • Shortly before you reach the castle ruins, the trail again crosses a meadow running alongside the stream.
  • On the enclosure the signs direct you to the left and a wonderful panorama of the ruins.
  • A small asphalt road then leads you to the museum in front of the castle. Visiting the Montaigle castle ruins (4) and enjoying the view is a must.
  • In front of the castle the trail leads to the old hamlet of ‘Marteau’ and its lovely limestone houses.

NOTE: if you wish to lengthen the ramble by several kilometres, you can cross the N971 here and get to Sosoye via Foy. Sosoye, just like Falaën, is one of the most attractive villages in Wallonia and definitely worth a detour to see.

From Sosoye, the trail leads back to Falaën. This detour takes about an hour and a half. At Marteau, the simple alternative course goes off to the left on a path that climbs across a wood (NOTE: there’s no signage at this point).

At a Y-junction, it turns right on to the lofty plateau known as ‘La Héronnière’. A little later, an asphalt farm track leads you back across the fields to Falaën.

Prepare your walk

Make sure you wear good hiking boots and comfortable walking shoes. A walking stick will also help.

Always take some snacks and water with you.

Author’s Tips

Falaën is one of Wallonia’s most beautiful villages. If you have time, a ride on a ‘draisine’ rail-trolley is one of the region’s most enjoyable experiences. Also recommended: ‘La Fermette’ restaurant lies directly on the route (www.lafermette.be). There are very nice chambres d’hôtes at Falaën. The Benedictine abbey of Maredsous (beer and cheese) is also nearby.

In the downloadable brochure below, we have selected one of the best walks per province: natural gems, family friendly paths, memorable views along the way, trails sprinkled with history… One even will introduce you to the iconic abbey beers.

A walker's guide to Wallonia

If you were to draw a straight line on an atlas northward from the Massif Central in France to the North Pole, the only area of high ground the line crosses is the Ardennes, shared between Belgium, Luxembourg and Germany – but mainly belonging to Wallonia, the southern part of Belgium!
