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.

In Flemish Brabant, the term 'canyons' refers to unique topographical features such as deep valleys, hollow roads, and significant erosional landscapes, rather than traditional large, deep geological canyons. These areas offer scenic and engaging experiences for visitors, characterized by deeply incised paths and picturesque valleys.
Visitors frequently enjoy the Valley of the Artists (Wijnbrondal), known for its picturesque valley and sunken road. Other popular spots include Hollow Way and Steps Huldenberg, which offers a hollow road with a nice view and stairs, and the Deep sunken lane, a beautiful 10-meter deep sunken road contrasting with rolling fields.
Flemish Brabant's geology primarily consists of subsurface layers like the Brussels Formation, made of shallow marine sandstone and calcareous sands from the Eocene epoch. The Brabant Massif is another ancient, concealed slate belt. While these are not surface canyons, the region's 'gorges' and hollow roads are formed by erosion through these types of geological materials, creating unique landscapes.
Yes, several areas are suitable for families. For instance, the Zuun Valley near Oudenaken is noted as family-friendly, offering a true expedition into the animal kingdom with diverse habitats. Many of the region's hollow roads and forest trails are also accessible for family walks.
You can expect to see diverse landscapes including forests (beech, oak-hornbeam), meadows, hayfields, moors, and wetlands. The Zuun Valley, for example, is home to numerous breeding and migratory birds, butterflies, and plants. The National Park Forests of Brabant, connecting areas like Hallerbos and Sonian Forest, are known for impressive trees and rich wildlife.
The best time depends on your interest. Spring, particularly around mid-April, is stunning for areas like Hallerbos (The Bluebell Forest) when wild hyacinths bloom. Generally, spring and autumn offer pleasant temperatures for hiking and enjoying the vibrant foliage. Summer is also good, with hollow roads providing shade, as noted by visitors.
Yes, Flemish Brabant offers a range of trails. Many hollow roads and valleys are considered intermediate, such as the Hollow Way and Steps Huldenberg. Some trails, like the double sunken lane or Vernagelstraat, can be more challenging, especially after rainfall. You can also find easy hikes in the region.
Beyond exploring the 'gorges' and hollow roads, Flemish Brabant offers a variety of outdoor activities. You can find numerous waterfall hikes, mountain biking trails, and general easy hiking routes throughout the region.
Many natural areas and trails in Flemish Brabant are dog-friendly, but it's always advisable to check local regulations or signage at specific locations. Generally, dogs are welcome on leash in most public natural spaces and forests.
Yes, many of the 'gorges' and hollow roads offer scenic viewpoints. For example, the Hollow Way and Steps Huldenberg provides a nice view from the top. The Valley of the Artists is also known for its picturesque setting. The contrast between the depth of sunken roads and the vastness of rolling fields also creates beautiful vistas.
Visitors appreciate the unique character of the hollow roads, often describing them as a 'blessing for nature with their special ecosystems' and 'a blessing for hikers on hot days' due to the shade they provide. The contrast between the deep, incised paths and the open, rolling fields is also frequently highlighted as beautiful. The diverse landscapes and opportunities for wildlife spotting are also popular.
Yes, many towns and villages adjacent to or within short distances of these natural areas offer cafes, pubs, and restaurants where you can refresh yourself after a walk. It's recommended to check local listings for specific locations you plan to visit.
Comfortable hiking shoes with good grip are recommended, especially as some trails can be technical or muddy after rainfall. Layered clothing is advisable to adapt to changing weather conditions. Depending on the season, consider waterproof outerwear and sun protection.
