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.

Tongeren's landscape features unique natural corridors known as "hollow roads" (holle wegen), which are deeply eroded paths with high earthen walls, rather than traditional geological canyons. These offer a distinct natural experience, often covered with dense vegetation. You'll also find areas like the Teuvenderberg forest reserve with spectacular descents through these sunken paths.
Yes, the Kanne Caves are a significant historical site. These are extensive man-made marl caves, mined since before the 15th century, used for building materials. Today, they host guided tours where you can learn about quarrying, see prehistoric animal murals, and discover their current uses for mushroom cultivation and beer storage. It's a cool retreat after a warm day.
Beyond the Kanne Caves, you can explore trails like the Unpaved trail through the Teuvenderberg forest reserve, which features a deep sunken road. Another notable feature is the Hollow Way, a classic example of these deeply worn paths that are a result of centuries of use and erosion, particularly beautiful in the hilly Haspengouw region. You can also find trails with enormously high walls, offering a unique walking experience.
Many of the natural areas and hollow roads are suitable for families, offering gentle topography and scenic walks. The Kanne Caves are specifically noted as family-friendly, providing an educational and cool underground experience. When exploring hollow roads, be aware that some paths can become quite soggy after rainfall.
Generally, dogs are welcome on trails in the natural areas around Tongeren, including the hollow roads and forest reserves. However, it's always best to keep them on a leash and check for any specific local regulations or signage in nature reserves like De Kevie, which might have areas sensitive to wildlife.
The spring and autumn months are ideal for visiting. In spring, the surrounding Haspengouw region is famous for its blooming orchards, and the hollow roads are lush with greenery. Autumn offers beautiful foliage. Summer can be pleasant, but some trails, especially the hollow roads, can become overgrown with nettles and blackberry bushes, and potentially muddy after rain. Winters can be cold, but offer a different, stark beauty.
Expect rolling countryside with distinct "hollow roads" that are sunken paths, often with steep earthen walls. The terrain can be varied, including unpaved forest trails and paths through wet meadows in areas like De Kevie Nature Reserve. After rainfall, some hollow roads can become quite soggy, so appropriate footwear is recommended.
Yes, there are mountain biking opportunities. For example, you can find a Narrow Descent Passage in Gully which is specifically for MTB, though it's noted as challenging and potentially dangerous. For more extensive mountain biking, you can explore the MTB Trails around Tongeren, which include routes in the Hoge Kempen network with varying difficulty levels.
The region around Tongeren is excellent for various outdoor activities. Besides exploring the hollow roads, you can enjoy extensive cycling. There are numerous Road Cycling Routes around Tongeren and Traffic-free bike rides, taking you through the scenic Haspengouw landscape, past orchards, and through charming villages.
Given the varied terrain, especially the potential for soggy conditions in hollow roads after rain, sturdy, waterproof hiking boots are highly recommended. Depending on the season, consider long trousers to protect against nettles and brambles. Bring water, snacks, and a map or GPS device, as some paths can be less clearly marked. A camera is also a must for capturing the unique scenery.
Most trails through the hollow roads and forest reserves are considered intermediate, offering a good balance for casual hikers and those seeking a bit more challenge. Some specific sections, like the Narrow Descent Passage in Gully, are rated as challenging, particularly for mountain biking, and require caution or skill.
Tongeren itself offers a variety of cafes, restaurants, and pubs. In the surrounding villages and towns within the Haspengouw region, you'll also find local establishments where you can enjoy a meal or a refreshing drink after your outdoor activities. It's advisable to check opening hours, especially in smaller villages.
