Those interested in the history of early Belgium should make a detour to marker no. 4 on the Porallée and its information panel, which recounts local disputes from themid-19th century.
The Ninglinspo and the Charmille du Haut-Marais
The Ninglinspo is that Walloon stream described by some tourist organisations as ‘mountainous’ and which all Belgians and Dutch people rush to come and admire. So, yes, certainly, it is picturesque and as wild as you could wish for, with footbridges, waterfalls and glacial potholes known as the Baths of the Naiads, Diana, Hermes, the Otter, the Stag, etc... but frankly, there is nothing mountainous about it.
Above all, go for a walk there during the week, as weekends, public holidays and school holidays are best avoided if you appreciate peace and nature.
The second main point of interest is the arbour planted in themid-19th century on the edge of his Haut-Marais estate. Despite being partially destroyed—by more than 40%—after German tanks passed through in 1940, it remains the longest in Europe, still stretching for 573 metres.

A tributary of the Amblève and 3.5 km long, with an average gradient of 7.5%, the Ninglinspo is one of the few torrents in Belgium. Come and discover this valley, which was coveted by gold prospectors in the last century, and walk in a landscape worthy of the highest mountain rivers. With its waterfalls and "baths", the Ninglinspo will offer you an unforgettable moment of relaxation. As for the Chefna, less popular with tourists, it will take you away from it all with its wild side.
