The route passes through the Florennes National Forest, then the municipal forest of Villers-le-Gambon, and, finally, a portion of a private forest. The forest primarily comprises an old grove of ancient oak trees, which has been rejuvenated by various leafy or coniferous plantings. Florennes National Forest was selected as a Natura 2000 site. The black woodpecker and the middle spotted woodpecker live side by side with deer and wild boar. Various species of dragonfly, butterfly, birds and mammals have also sought refuge in the forest and its sun-soaked borders. There are also blankets of orchids here in June for you to view with pleasure. Picking is forbidden, in order to preserve this special flower.
