The path does indeed continue here, but it is not very visible. Keep a close eye on the Komoot map, and with a bit of luck, you'll be able to find and follow the trail.

It's a shame that the forest paths that aren't part of a hiking, cycling, or mountain biking network aren't well-maintained, making them difficult to navigate. I'd say: everyone should go there, because the hiker or cyclist makes the path!

The Duck Farm was formerly part of the large park of the Princes of Ligne's castle; it was here that ducks were hunted to grace the tables of the lords of the manor, hence its name. Nowadays, it is a haven for amphibians, dragonflies, and other insects.
