The Ourthe is the historic river of the Ardennes massif for kayaking. It divides into two very different realities: the upper Ourthe (Nisramont–La Roche, 18 km), wild and technical with a heavy physical commitment, and the lower Ourthe (Durbuy, Hamoir), geared to mass entertainment with short routes of 4 to 8 km.
But here is what they don't tell you: in Durbuy you pay 27-32€ for only 4 to 8 km, in an overcrowded “theme park” atmosphere. The Nisramont route takes 3 to 6 hours and an advanced level. About 1 hour away by car, the Semois offers you 4 routes of 7 to 17 km in a National Park from 26.40€, on a calm class I river that suits everyone.
With National Park status since December 2022, a calm river, unbeatable prices and Natura 2000 nature, the Semois beats the Ourthe on every count.

The Semois is the first National Park of Wallonia. Unlike the Ourthe, it has the benefit of an active programme of bank and spawning-ground restoration, which guarantees a sustainably protected environment. Discover the National Park.
The Semois is a calm and steady river (class I), shallow in summer: if you capsize, you can usually stand. The upper Ourthe (Nisramont) is technical and demands a lot physically. Accessible from age 6 on the Semois.
For a family of 4: up to 76€ savings (35€×4=140€ on the Ourthe vs 26€×4=64€ on the Semois). Transparent all-inclusive pricing, with no hidden fees. Get exclusive discounts.
A few sections of the Ourthe are often unsuitable for everyone. The Semois offers 4 routes for all levels. Take the quiz to find yours.
The Semois crosses award-winning Natura 2000 areas. Ancient forests, wild meanders and schist cliffs, with grey herons, kingfishers and wild brown trout. It is nicknamed the « Little Belgian Amazon ».
In Durbuy, kayaking has become an « industrial » leisure-consumption activity. On the Semois: 5 times fewer people, sometimes 30 minutes without meeting anyone. That is the real luxury of the Ardennes.
The Tombeau du Géant (Bouillon), the Pont de Claies made of woven hornbeam branches, the artist village of Vresse-sur-Semois and the classified villages such as Laforêt. A cultural richness the Ourthe cannot match.
The only operator in Belgium with real-time water-level monitoring. No more nasty surprises and forced portages such as those on the Ourthe in summer.
On the Semois, the price includes: return shuttle, sealed dry bag, vest, light paddle and also changing rooms. On the Ourthe, transport or the dry bag may carry surcharges.
Our campsite on the bank of the Semois allows full weekends. Kayak + overnight + shower from 45€/person. This is impossible on the Ourthe at such value for money. See the campsite.
This is one of the most photographed landscapes in Belgium. Seen from the water, the perfect meander takes on a monumental dimension. Legend has it that a giant Gaulish warrior threw himself in to escape the Romans.
It was the cradle of the “School of Vresse”, where landscape painters such as Albert Raty immortalised the valley. Arriving by kayak, you see the Saint-Lambert bridge, whose narrowness is legendary.
A classified village whose old tobacco-drying barns still stand. The Pont de Claies, a seasonal structure of woven hornbeam branches, is rebuilt by volunteers every spring. It is a unique experience in Belgium.

"We did Durbuy every year but it became a theme park. Kayak Belgique introduced us to the Semois: National Park, no crowds and herons everywhere. And 11€ less per person!”
“I spent 10 years on the Ourthe before I found the Semois. Calm river, safe for the children. The Tombeau du Géant seen from the water is magical. And the quiz found us the perfect route."
“Nisramont is beautiful but far too technical for our children, aged 6 and 8. On the Semois: a calm, shallow river where you can stand everywhere. Plus the riverside campsite for a full weekend. Unbeatable.”
"The real-time water level system changed how we plan. On the Ourthe you end up carrying your kayak over the stones in summer. Here: complete freedom and perfect conditions guaranteed."
Our base in Alle-sur-Semois (Vresse-sur-Semois) is reachable by car: ~1h15 from Durbuy, ~1h from La Roche-en-Ardenne, ~1h10 from Namur.
Also reachable by train (SNCB) with a FREE shuttle from the station to the starting point, included in the price. Parking on site is free.
📍 A trip slightly longer than to the Ourthe? Yes, but it is well worth it: National Park, calm river, lower price and unique heritage.
📍 Address: Rue du Pont 1, 5550 Vresse-sur-Semois, Belgium
The Ourthe kayak descent is a flagship activity of the Belgian Ardennes. The Ourthe splits into two segments: the upper Ourthe (Nisramont–La Roche, 18 km in a Natura 2000 area), a prestigious but technical route that takes 3 to 6 hours and an advanced level, and the lower Ourthe around Durbuy, “the smallest town in the world”, where kayaking has turned into a mass-consumption activity on short routes of 4 to 8 km.
Facing this model, the Semois Valley stands out as a new paradigm. Raised to National Park status in December 2022, it reconciles protecting biodiversity with sustainable tourism. The Semois is a class I (easy) river, calm and shallow in summer, which makes the activity accessible from age 4 on certain sections.
With Kayak Belgique, you benefit from transparent all-inclusive pricing (shuttle, sealed dry bag, vest, paddle and changing rooms), from real-time water-level monitoring, from flexible booking and from an campsite integrated on the bank of the Semois.
The Semois also has a unique cultural heritage: the Tombeau du Géant in Bouillon, the Pont de Claies of woven hornbeam branches at Laforêt (rebuilt every spring), the artist village of Vresse-sur-Semois and its historic landscape painters. This artistic and cultural dimension is one the Ourthe cannot rival.
