I recommend this route without hesitation, it is a beautiful forest, I just visited it a few weeks ago and was amazed; in full growth stage of the hyacinths or bluebells. A must-see destination in Brussels.

Superb forest path, in relatively good condition and with a gentle slope. Be careful, it can be quite slippery when it's wet.

Away from the hustle and bustle. Enjoy the mystical Livierenbos. The mystical Livierenbos is a large old forest with open spaces located on the border of the Flemish Ardennes and Pays des Collines. In this large forest, too, the bluebell is the main character every year in April. Historical significance: the name of the forest – in French Bois de la Louvière – is Romanesque in origin and refers to the presence of wolves. Wolves lived in the forest until the 17th century, which regularly led to fierce hunts. With the knowledge of the past (werewolves) and the possible appearance of flying witches, it is doubly enjoyable and we stroll dreamily along blue-purple carpets through the present.

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.
