The complete guide to the 3 Lesse routes from Houyet
9 km · 12 km · 21 km to Anseremme · Dinant Evasion prices · SPW regulations
Back to the Lesse descent guideThe Lesse kayak descent from Houyet is among the most popular water activities in the Belgian Ardennes. Nestled between dizzying limestone walls and centuries-old forests, the Lesse offers an exceptional natural setting, a few kilometres from the legendary Han Caves. Every season, tens of thousands of kayakers paddle its lively waters from Houyet station, a listed Ardennes village whose history goes back to the Middle Ages.
This complete guide — written by Quentin Deligne, river hydrology expert and founder of Kayak Belgique, presents in detail the three routes on offer, the updated 2026 prices of the operator Dinant Evasion and the regulatory framework imposed by the Public Service of Wallonia (SPW), along with an objective comparison between the Lesse and the Semois to help you choose the river that best meets your expectations.
Navigation on the Lesse is organised for all levels and all wishes, from a family outing to a full-day sporting challenge.
The Lesse's full route, starting from Houyet station. The valley is dominated by wooded slopes and limestone walls sculpted by millennia of erosion. This section has one particularity: the crossing of two weirs, designed to bring a touch of adrenaline accessible even to beginners. Ideal for those who want total immersion in the Namur Ardennes.
The best-balanced route, much appreciated by families and groups. It brings together the river's most spectacular stretches, notably the majestic passage at the foot of Walzin Castle, a medieval fortress perched on a limestone promontory, and the impressive Chaleux Needles, listed rock formations. Both weirs are included, giving the same thrill as the long route.
The most serene route, designed to offer an experience of complete tranquillity. Its particularity: no weirs, no technical difficulty. The river winds almost entirely in the shade of trees, in a bucolic setting that nature lovers will appreciate. It is the perfect option for families with young children, beginners and those who want to combine river gliding with hiking, such as the famous Promenade des Échelles de Chaleux.

Two ways of access lead to the Lesse boarding points from Houyet:
Park free of charge at Anseremme (Rue du Vélodrome 15, 5500). Collect your tickets, then the operator's shuttle takes you to Houyet or Gendron. At the end of the descent you find your vehicle right there, with hot showers, changing rooms and catering on site.
The SNCB 166 Dinant–Bertrix line serves the stations of Houyet, Gendron-Celles and Anseremme, all less than 100 m from the boarding points. Eco-responsible option: the without-shuttle formula saves €2.50/pers.
Kayaking on the Lesse is strictly regulated by the SPW-ARNE Directorate of Non-Navigable Watercourses to protect the river's biodiversity while ensuring user safety.

In the face of growing tourist pressure, the Lesse operating permit has been renewed with stricter environmental conditions. Daily capacity has been reduced by 20%, now setting a limit of 1,169 kayaks maximum per day. This measure aims to preserve the balance of wildlife, reduce noise for residents and ensure the long-term future of the activity in the Haute Meuse Namuroise Nature Park (PNAM, 94,500 ha).
👉 Tip: In July–August, slots go fast. Book your kayak several weeks in advance, especially for groups of 20 or more.
The Lesse descent is part of a complete leisure offer, for tailor-made days:
In the Lesse gorges, mobile coverage is almost non-existent. Phones and car keys are the items most often lost. Leave your keys in storage at the base and keep your phone in a waterproof pouch, placed in the bucket supplied.
