Zoniënwoud Forest Reserve Trail

Highlight • Trail

This forest reserve offers a varied terrain with challenging trails, rolling hills, and dense forests, making it perfect for an adventurous trail run.

The forest reserve itself is a protected area consisting mainly of deciduous forests, streams, and open grasslands. The route is ideal for trail running due to the natural relief of the terrain: you will regularly encounter forest floor, roots, muddy sections, and the occasional tough climb.
