There is a tree across the path. You can still pass it.

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 'canyons' around Chaumont-Gistoux are not large-scale geological formations but rather deeply incised paths and eroded features, often referred to locally as 'chemin creux' or sunken paths. These are typically found in areas with old sand quarries or along river valleys, creating unique, tunnel-like walking experiences with high earthen banks.
Visitors frequently enjoy exploring several unique sunken paths. The Tangissart Toboggan is a popular trail featuring a narrow mini ravine that widens into a slide-like descent. Another well-liked spot is Hollow Way and Steps Huldenberg, an intermediate trail with a hollow road and stairs offering views. The Hollow Way through a forest is also appreciated for its dynamic descents.
Yes, some of the sunken paths are suitable for families. For instance, the Tangissart Toboggan is categorized as family-friendly, offering a playful descent with different tracks and small jumps that can be fun for all ages.
The region offers a diverse natural landscape of woodlands, fields, and small valleys. You'll encounter deeply eroded paths, high earthen banks, and forest sections. The area is part of the Brabant Ardennes, characterized by varied topography and tranquil, unspoiled natural environments, including streams like the Ry du Pré Delcourt.
Beyond exploring the sunken paths, the region is excellent for various outdoor activities. You can find numerous hiking trails, including moderate routes like the 'Riverside Path in Longueville' or the 'Bonlez Wood' loops. For cyclists, there are MTB trails and gravel biking routes that traverse the varied terrain.
The 'chemin creux' or sunken paths are formed by centuries of erosion from foot traffic and water, particularly in areas with soft soil, often near old sand quarries. This process carves deep channels into the landscape, creating the distinctive high earthen banks and tunnel-like effects that characterize these features.
Some sunken paths can become quite challenging after heavy rainfall. For example, the Beautiful sunken lane can be 'quite acrobatic' in wet conditions. It's advisable to wear appropriate footwear and be prepared for potentially muddy or slippery sections. Some descents, like the Hollow Way, can also be fast and tricky.
Visitors particularly enjoy the unique character and immersive experience of these paths. Many appreciate the playful descents, the feeling of being far from civilization in the deep sunken roads, and the natural beauty of the surrounding forests and countryside. The varied terrain also offers dynamic experiences for hikers and mountain bikers alike.
Yes, some sunken paths are popular with mountain bikers. The Hollow Way and Steps Huldenberg, for example, is described as slightly technical but still suitable for beginner mountain bikers. The Tangissart Toboggan also offers different tracks and small jumps for a fun ride.
Many of these sunken paths, such as the Stockemstraat, are old, historically significant routes that have been used for centuries. They connect villages and traverse the landscape, offering a glimpse into the region's past as important thoroughfares. The local 'Paths and Trails Group' often highlights these features during guided walks, sharing their historical significance.
While the sunken paths can be explored year-round, spring and autumn often offer the most pleasant conditions with mild temperatures and beautiful foliage. During these seasons, the paths are less likely to be extremely muddy or dusty. However, after heavy rainfall, some sections can become challenging, so checking local weather conditions is always recommended.
