The Semois valley in the Belgian Ardennes Top 0.1% of the world's fastest websites — KayakSemois-Ardenne

Semois Valley National Park — Since its official classification in December 2022, the Semois National Park has established itself as the ultimate natural sanctuary of Wallonia.
Paddling with the KayakSemois-Ardenne fleet means having the immense privilege (and responsibility) of navigating in the first Belgian national park dedicated to reconciling canoeing and kayaking with a highly protected hydromorphological ecosystem.
Our Strict Responsible Kayaker Charter:
Respect for animal tranquillity: Navigate slowly and silently to never disturb nesting birds or forest mammals.
Zero trace, zero waste: Take EVERYTHING you brought with you.
No wild swimming or wild camping outside marked zones.
