The impressive purple carpet of wild bluebells transforms the Bois de l'Étoile into a fairytale forest every spring. The absolute peak period to admire this unique floral splendor is usually between mid-April and early May. As the bloom only lasts about two weeks, timing is crucial. Caution: in this fragile zone around L'Étoile, strictly stick to the official paths to avoid trampling the young bulbs!

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.
