The Ourthe is the historic river of the Ardennes massif for kayaking. It splits into two very different realities: the upper Ourthe (Nisramont–La Roche, 18 km), wild and technical with a high physical commitment, and the lower Ourthe (Durbuy, Hamoir), geared towards 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 just 4 to 8 km in an overcrowded « theme park » atmosphere. The Nisramont route requires 3 to 6 hours and an advanced level. About 1 hour's drive away, the Semois offers you 6 routes from 7 to 26 km in a National Park from 26€, on a calm class I river suitable for everyone.
A National Park since December 2022, a calm river, unbeatable prices, Natura 2000 nature: the Semois beats the Ourthe in every respect.

The Semois is the first National Park of Wallonia. Unlike the Ourthe, it benefits from an active programme of bank and spawning-ground restoration, guaranteeing 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 physically demanding. 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.
The Ourthe offers a few sections that are often not suitable for everyone. The Semois offers 6 routes for all levels. Take the quiz to find yours.
The Semois crosses award-winning Natura 2000 areas. Ancient forests, wild meanders, schist cliffs. Grey herons, kingfishers, wild brown trout. 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. 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 with no equal on the Ourthe.
The only operator in Belgium with real-time water-level monitoring. No more nasty surprises and forced portages like on the Ourthe in summer.
On the Semois, the price includes: return shuttle, sealed dry bag, vest, light paddle and changing rooms. On the Ourthe, transport or the dry bag may be subject to surcharges.
Our campsite on the bank of the Semois allows full weekends. Kayak + overnight + shower from 45€/person. Impossible on the Ourthe with such value for money. See the campsite.
One of the most photographed landscapes in Belgium. This perfect meander, seen from the water, takes on a monumental dimension. Legend has it that a giant Gaulish warrior threw himself in to escape the Romans.
Cradle of the « School of Vresse », where landscape painters such as Albert Raty immortalised the valley. Arriving by kayak offers the sight of the Saint-Lambert bridge, whose narrowness is legendary.
A classified village with its old tobacco-drying barns. The Pont de Claies, a seasonal structure of woven hornbeam branches, is rebuilt every spring by volunteers. 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, herons everywhere. And for 11€ less per person!"
"After 10 years on the Ourthe, I discovered 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. The Semois: calm river, shallow, you can stand everywhere. And the riverside campsite for a full weekend. Unbeatable."
"The real-time water level system changed the way we plan. On the Ourthe, you end up carrying your kayak over the stones in summer. Here: total freedom and guaranteed perfect conditions."
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. Free parking on site.
📍 A slightly longer trip than the Ourthe? Yes, but it is well worth it: National Park, calm river, lower price, 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 requiring 3 to 6 hours and an advanced level, and the lower Ourthe around Durbuy, « the smallest town in the world », where kayaking has become a mass-consumption activity with 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 biodiversity protection and sustainable tourism. The Semois is a class I (easy) river, calm and shallow in summer, making 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, changing rooms), from real-time water-level monitoring, from flexible booking and from an integrated campsite on the bank of the Semois.
The Semois also offers a unique cultural heritage: the Tombeau du Géant in Bouillon, the Pont de Claies made of woven hornbeam branches in Laforêt (rebuilt every spring), the artist village of Vresse-sur-Semois and its historic landscape painters. An artistic and cultural dimension the Ourthe cannot rival.
