The Ninglinspo Valley: the origins of a protected site
Formed where the Hornay and Blanches Pierres streams meet at a place called “La Fourchette,” the Ninglinspo is a major geological curiosity in the Liège Ardennes. Composed of quartzite, schist, and phyllite, this site bears witness to the Ardennes’ first marine shoreline, which emerged some 400 to 500 million years ago. With its steep 7.5% gradient, this small tributary ofthe Amblève resembles a veritable torrent that plunges down over 3 kilometers, carving out gigantic rocks, waterfalls, and curious potholes hollowed out by the force of the water.
At the end ofthe Ancien Régime, cartographers confused the original name of the stream, the “Doulneux,” with the locality where it flows into: “En Inglin spau,” meaning theInglin spring. The charm of its natural pools owes much to Laurent-François Dethier, who named them after mythological figures such as the Baths of Diana, Venus, orHermes. This wild paradise was ultimately spared from urban destruction and developed in 1918, before being officially designated a protected site in 1947.
A legendary hike: footbridges, panoramic views, and wild nature
The Ninglinspo Trail is, without a doubt,one of the most beautiful hiking routes in the Belgian Ardennes. Starting from the village of Sedoz, the route takes you on a spectacular ascent along this unique torrent. To follow the flow of the water, numerous wooden footbridges dot the canyon, offering fun crossings and magical views of the waterfalls and natural pools. Although children build stone dams along the riverbank, this hike remains a real physical challenge.
Halfway through, your efforts are rewarded with a must-see stop at the Drouet viewpoint, a breathtaking panorama that leaves you speechless. To extend the adventure after admiring the famous Roches Crahay, a break at the Brasserie Elfique is a must. It’s the perfect place to recharge while enjoying a local beer with the flavors of the region. An unusual and spectacular stop, just 1.5 hours from the capital.
