Beautiful valley of this side stream of the Ourthe. You first have to descend steeply with an auxiliary rope, then you walk along the stream to its mouth in the Ourthe. Photogenic corners along the way, including a small waterfall.

The Deux Ourthes Natural Park is characterized by striking river gorges and deep river valleys, rather than traditional large-scale canyons. These features are carved by the Eastern and Western Ourthe rivers into the ancient Rhenish schist massif, creating rugged terrain, impressive rocky formations, and steep, forested valleys. You'll find craggy reliefs and remarkable rocky ridges throughout the park.
One of the most iconic viewpoints is View of the Ourthe meanders from Le Hérou, offering breathtaking views of the Ourthe river winding through wooded meanders. Another excellent spot is Le Hérou Viewpoint and the Ourthe Valley, which provides panoramic views of the valley and the impressive vertical rock slabs of Le Hérou, which are about 1,000 meters long and 80 to 90 meters high.
Yes, the Bellemeuse Valley is a significant nature reserve known for its rich biodiversity. This deep U-shaped valley, formed by the Bellemeuse stream, is a landmark in the heart of the Eastern Ardennes. Efforts have been made to restore its natural wealth after past logging, making it a valuable ecological site.
The park offers diverse hiking experiences, ranging from challenging trails to scenic paths. Around Le Hérou, you can discover small, challenging trails with adventurous sections, sometimes described as 'almost via ferrata' in dry weather. Other areas feature steep descents, like the path leading to the Ourthe valley from Steep descent., or trails along streams with photogenic corners and small waterfalls, such as in the Pis de Vache Valley.
Beyond exploring the gorges, the park offers a variety of outdoor activities. You can find numerous routes for gravel biking, including challenging routes like the Houffa Gravel Fondo. There are also many easy hikes, such as the 'Fairies, dwarves and beavers in Achouffe' trail, and extensive MTB trails, including parts of the Houffalize World Cup Circuit.
The Le Hérou area can be adventurous for families. While there are normal hiking trails with nice views, some paths, especially those descending to the Ourthe valley and climbing back up, are described as challenging. These can be exciting for 'big and small heroes' seeking an adventure, but might require supervision and are not recommended in wet weather due to steepness.
The Deux Ourthes Natural Park is beautiful year-round, but spring and autumn often offer the most pleasant conditions for hiking and exploring. Spring brings lush greenery and blooming flora, while autumn showcases vibrant fall foliage. Summer is also popular, but some challenging trails, especially those with steep sections, might be less comfortable in very hot or wet weather.
The park's dramatic landscape was formed by the two branches of the Ourthe river, which have carved deep, forested valleys into the Rhenish schist massif. This massif consists of Belgium's oldest rocks. This geological process created the distinctive 'craggy reliefs' and 'remarkable rocky ridges' that characterize the region's gorges and valleys.
Visitors particularly enjoy the dramatic natural beauty and the sense of adventure. The breathtaking panoramic views from viewpoints like Le Hérou, the wild and untamed beauty of the Ourthe valley, and the varied, sometimes challenging, trails are frequently highlighted. The opportunity to discover rich biodiversity in areas like the Bellemeuse Valley also adds to the appeal.
Some trails in the park, particularly around Le Hérou and in valleys like Pis de Vache, involve steep descents and rocky sections. For instance, the Pis de Vache Valley requires an auxiliary rope for a steep descent. It's advisable to wear appropriate footwear, be prepared for varied terrain, and exercise caution, especially in wet conditions when paths can become slippery.
