Organization & Booking

Advance booking: Book your kayaks at least 48 hours in advance, especially in high season (July-August). This allows us to guarantee equipment availability, prepare your welcome, and provide you with the latest weather info.

Pro tip: Morning slots (10 am - 12 pm) are often less crowded and allow you to enjoy the river more peacefully.

Protection against the elements

Sun protection kit: Water reflection intensifies UV rays. It is essential to bring:

• Waterproof sunscreen (SPF 50+)
• Cap or wide-brimmed hat
• Sunglasses (polarized preferred)

Our rental includes waterproof buckets to protect your valuables (phone, keys, wallet) from splashes.

Location & Environment

Starting base: Kayak Ardenne, 5550 Alle-sur-Semois, Belgium.

Eco-responsibility: We participate in the "Clean Semois" charter. We provide airtight buckets for your waste and give you instructions to respect the fragile banks and local wildlife.

Equipment & Comfort

Shoes

Opt for shoes that stay firmly on your feet and can get wet: water sandals, old sneakers, or neoprene socks. Avoid flip-flops, as they are very easily lost!

Clothing

We recommend a swimsuit under comfortable clothes (shorts, synthetic t-shirt). Always bring a full set of dry clothes in your waterproof bucket to be comfortable after the activity.

Safety & Communication

Mobile phone: Essential, especially for long routes. Make sure it is fully charged and store it in the provided waterproof bucket.

In case of emergency: The European emergency number is 112. Our rescue team is also available 7 days a week during the season.

Bad weather: Your safety comes first. We offer free cancellation in case of an official weather alert (thunderstorms, heavy rain) or a possible postponement.
