Le Hérou

Le Hérou is one of the most striking viewpoints in the Belgian Ardennes — a rocky ridge rising above a bend of the Ourthe river, near the village of Nadrin, in the municipality of Houffalize. The rock mass stretches close to a kilometer in length, reaching about 80 meters in width at its base and more than 80 meters in height. The site lies within the Deux Ourthes Nature Park (Parc naturel des Deux Ourthes), which spans six municipalities: Bertogne, Gouvy, Houffalize, La Roche-en-Ardenne, Sainte-Ode and Tenneville.

Where does the name come from?

Local legend claims that a herald once proclaimed sentences handed down by the High Court of Nadrin from the top of this rock. The story is often cited as the origin of the site's name, though like many folk tales its historical accuracy is difficult to confirm.

What can you see from the top?

The panorama from the Hérou ridge is one of the most distinctive in the region — the Ourthe river winds through a deep gorge, wrapping around the rocky spur on almost every side and creating a scene some compare to landscapes in the French Alps. The rock was once entirely stripped of vegetation, which further emphasized its raw, monumental silhouette against the green slopes of the valley.

The site has been a protected, classified rock ridge since 1937 and carries a two-star rating in the Michelin Green Guide — a rare distinction for this part of the Ardennes.

How do you reach the top?

The most popular way to explore the site is a roughly 6-kilometer walking loop known as the "Promenade du Hérou," starting in Nadrin, running along the ridge and back to the starting point. The descent from the rock can be steep and occasionally tricky underfoot, and is not recommended for young children — but the reward, a sweeping view over the river's meanders, makes the climb worthwhile.

In Nadrin itself, right above Le Hérou, stands the Six Ourthes viewing tower (Tour d'Orientation des Six Ourthes), offering a 360-degree panorama over the surrounding hills and valleys — a natural complement to a walk along the rocky ridge.

Frequently asked questions

Is climbing Le Hérou difficult? The approach trail is moderate, but the descent along the ridge can be steep and slippery after rain, so proper footwear is recommended.

How long does a visit take? The full walking loop around Le Hérou typically takes 1.5–2 hours at a relaxed pace, depending on how many stops you make for photos.

Is it worth combining with the Six Ourthes tower? Yes — both viewpoints are close together in Nadrin and together give a fuller picture of the Ourthe valley landscape.

Is the site suitable for families with children? Because of steep sections and a lack of railings in places, the trail requires caution and is not recommended for very young children.
