Hollow ways are typical small landscape elements in hilly areas with a loess subsoil. Most hollow ways presumably originated in the Middle Ages. Centuries of use of the same path, on foot or by horse and cart, led to a natural erosion process. Hollow ways therefore carry a piece of history with them and are thus part of our cultural heritage.

In the Neigembos, nature is allowed to evolve almost spontaneously. The trees can grow old and there is a lot of dead wood. Due to the danger of falling branches, it is important to stay on the paths. There is a rich plant growth: on the more acidic soils you will find mainly bracken, lily of the valley and woodruff. On the more loamy soils, you can enjoy wild hyacinth, wood anemone, wild garlic and yellow dead-nettle in the spring. The western part of the forest reserve, also known as the Vriezenbos, consists of, among other things, a spring forest with typical species such as black alder, common ash, marsh marigold, giant horsetail, bitter cress and the two species of lesser celandine. Enjoy the natural beauty with the help of the three mapped-out walks: the Dikke Beukenwandeling, the Bevingenwandeling and the Groebenwandeling. (Agentschap Natuur en Bos)

The area offers a rich variety of habitats: you'll walk through forests, grasslands, scrubland, and fields with varying degrees of moisture and nutrient richness. The calcareous springs in the south of the area foster a very specific flora in the central stream valley. Along the way, you'll encounter wild garlic, water plantain, wood anemones, and bracken, among other plants. (Visit Dilbeek)

A 90-hectare gem in the Green Belt, just a stone's throw from Brussels. This nature reserve is known for its rich terrain, with beautiful spring flora alternating between dry and marshy areas. Restored and newly constructed boardwalks—a total of approximately 370 meters—guide you comfortably through the valley without damaging the fragile, wetlands. The highlight of Wolfsputten is undoubtedly the new viewing platform, a popular stop or selfie spot. Want to know more? Click through to https://www.natuurenbos.be/natuurgebieden/wolfsputten

The Wolfsputten form a varied nature reserve with ravine forests, calcareous spring streams and rare flora such as wild garlic, orchids and giant horsetail. In this rolling landscape you walk along old sandstone quarries and deeply cut stream valleys that once provided the building materials for churches and town halls in Brussels, Ghent and Leuven. With more than 300 plant species and dozens of birds and mammals, this is one of Flanders' most biodiverse places.

The slightly more than 70 hectare Neigembos once covered almost all of central Belgium, together with the Sonian Forest and the Hallerbos, among others. In this mixed oak and beech forest on the border between the Flemish Ardennes and the Pajottenland you will find height differences from 20 to 90 meters above sea level. A few tough slopes await you here! The deep sunken roads have a distinct microclimate and are a pleasure to walk in. Especially in spring, when the bluebells, bellflowers and wild garlic roll out their colorful carpets. (Routen.be)

A 'Hollow Way' like the one in Neigembos is a road or path whose surface is significantly lower than the surrounding land, typically at least half a meter. It's formed by a natural erosion process: centuries of continuous use by people, horses, and carts on the same path cause loose soil to wash away with rainwater, gradually deepening the road year after year.
