This route has a diverse and fascinating wildlife, it also has its gentler sides, as this circuit will show. It’s a place of pilgrimage for mountain bikers and nature lovers alike.

From the village of Ondenval, we follow the country road that heads quickly into the wood of Thirimont. The route weaves in and out among the conifers before swooping down into the valley of the River Amblève.

At this point the river is wild and flows through an uninhabited area. Shortly after crossing it on a wooden bridge, we climb steeply to reach the Wolfsbusch wood. Beneath the changing canopies of spruce or broad-leaved trees, the forest presents a whole range of habitats: it’s like passing through an immense natural garden.

Our wheels cut a path between roots, moss and rocks. We have to tackle some fairly technical stretches before arriving on the Montenau plain, from where we can see the Vennbahn slicing through the landscape.

In 1880 Montenau witnessed a veritable gold rush. Gold panning continued until after the First World War, but in the end only a few nuggets were found.

The route traces a course along a line of hill crests as it heads back to Ondenval. We follow the path of the Amblève again before entering the Rohrbusch, another of the woods that encircle the village with nature.

Good to know!

The local tourist office offers audioguides called “circuits sonores” for tours around the region by bike or car, via iPod, Smartphone or mp3.
