This path is largely located on the banks of the IJse (a tributary of the Dyle) and is most pleasant on quiet days, as it is also popular with hikers.

Holleweg Huldenberg

Highlight • Trail

Typical hollow road to / from Huldenberg. When you are at the top, you can also connect to the Bloso mountain bike route from Overijse.

Beautiful! Veldweg 76 gives the adrenaline and the Stockmanstraat is like a haunted forest! For MTB's, and slightly technical. Road bikes can avoid this by taking the Koxberg. Please note …
