A sunken road is a road that is so deeply worn that it lies between two slopes. It is the result of centuries of use and erosion. The most beautiful sunken roads can be found especially in hilly areas with a subsoil that easily forms steep walls, such as in Haspengouw and Hageland.

The Spy Man Visitor Center is located in a former water supply station built in 1906 near the cave of the same name. Discovered in 1886, the Spy Man is affectionately known as Spyrou.

The Aulniats slag heap is an elongated and flat slag heap, with an unstructured look that culminates at 186 m. Its abundant vegetation, its viewpoints over the Sambre valley and its small "canyon" colored with reddish hues by the combustion of the shales are all discoveries that will punctuate your walk on the slag heap. Witness to the activity of the last Walloon coal mine, the Aulniats slag heap is an invitation to a bucolic outing for the whole family. It conceals so many unsuspected treasures! Thus, lovers of mining remains will be pleasantly surprised to discover industrial structures at its foot. Budding geologists will scrape the surface of the slag heap to discover the reddish shales, witnesses of the self-combustion of the slag heap. These red shales were also exploited until 2001 as backfill, in particular to stabilize the runway at Charleroi airport. As for photographers, they will enjoy the exceptional panorama offered by its summit plateau! Hikers, for their part, will be delighted to walk in an environment of high quality flora and fauna. A pedestrian connection is possible with the slag heap n°7 of the Gouffre located a few cables away.

Actually you can't watch beavers there, only the results of theirs activity. Probably, they hide from people during the daylight because of dogs
