Beautiful hike, with very beautiful views, with steep ascents with rocks and roots that you have to climb over, but really worth doing.

Beautifully located climbing area on the Ourthe with its own picnic area and here the sound of the river instead of, as is often the case in Belgium, the road and railway line. Actually, there is something for everyone, although the focus is on easier to intermediate routes. The rock is good, but not always perfectly solid.

The most popular natural rock formation is the Natural Rock Tunnel near Bomal, where you can walk through a natural tunnel. Other highly regarded spots include Caves and Cliffs along the Ourthe, which offers a hands-on caving experience in a quiet, natural setting, and the historically significant Porte Aïve Cave.
Yes, the Isbelle Karst Spring is considered family-friendly. Children can enjoy looking for the disappearing and reappearing water, making it an adventurous and engaging spot for all ages.
The region is rich in archaeological history. The Porte Aïve Cave is significant for its Neolithic tomb, dating back to 9900 to 3300 BC, discovered during excavations. Another important site is the Coléoptère Cave near Bomal, where international scientists made significant archaeological discoveries in the 1920s, including a cockchafer-shaped pendant.
Beyond traditional caves, you can explore the Isbelle Karst Spring, a fascinating natural phenomenon where the Isbelle stream disappears underground into sinkholes and then resurfaces at the 'Fontaine de Thot'. This process is particularly noticeable after heavy rains.
Many caves and natural rock formations in the region are accessible year-round. However, for sites like the Caves and Cliffs along the Ourthe, rocky paths can be very slippery in rainy weather, so drier periods might offer a more comfortable experience. For the Isbelle Karst Spring, observing the water's disappearance and resurgence is particularly dramatic after heavy rainfall.
Yes, the path leading to the Porte Aïve Cave involves a steep descent, making it a challenging but rewarding detour for geology enthusiasts. Similarly, the Caves and Cliffs along the Ourthe can be quite physical, especially on rocky paths during wet conditions.
The Manhay region offers a variety of outdoor activities. You can find numerous MTB Trails, Running Trails, and Gravel Biking routes. These guides provide options for different difficulty levels, allowing you to combine cave exploration with other adventures in the Belgian Ardennes.
While Manhay's immediate vicinity offers unique natural and archaeological sites, the broader Belgian Ardennes region hosts several renowned show caves. These include the impressive Caves of Han, known for their vast chambers and tram ride, the Caves of Remouchamps with their underground boat trip, and the multi-level Hotton Caves, Belgium's only classified cave.
When exploring caves and natural rock formations, it's advisable to wear sturdy footwear, especially for locations with steep or rocky paths like the Porte Aïve Cave or Caves and Cliffs along the Ourthe. Layers of clothing are also recommended as cave temperatures can be cooler than outside, even in summer.
Visitors appreciate the natural beauty and quiet surroundings, particularly at spots like the Caves and Cliffs along the Ourthe. The adventurous aspect of exploring natural rock tunnels, like the one near Bomal, and the historical significance of archaeological caves also receive high praise from the komoot community.
While not 'hidden' in the sense of being secret, the Isbelle Karst Spring offers a unique, less conventional 'cave' experience where the focus is on the natural hydrological phenomenon rather than large chambers. It's a good spot for those looking for something different from typical show caves.
