Great forest path

Highlight • Trail

I wouldn't describe it as a single track because it's too wide in front, but it's a nice fast driving trail with gravel surface. So also ideal for gravel bikes.

April 4, 2026,Da Brussel a Chateau de la Hulpe - Mtb track
Getting back on two wheels slowly. Gravel ride in the woods, which somehow always manages to reveal new little trails. Cyclist rescue after a blistering descent, who took a crazy flight into a tree, bending the front wheel.

Some very tough passages when leaving the Hulpe area (almost obligatory bike descent) but lots of fun too 😇
