In Belgium’s first official National Park, the Hoge Kempen, you can find a scenic long-distance hiking route of approximately 100 kilometers. The region was previously known for its mining industry, and this is still very present today, as you will experience along the route. Also, with a bit of luck, you may even spot wildlife (we saw a few deer).
The route is well-marked with signs in both directions. It will take you through many forests, but one of the most unique features is the frequent presence of slag heaps, man-made hills from the mining industry that remain from the area’s coal mining era. These are also the source of all elevation gain during the hike.
