• Strong swimmers only: everyone must swim 25 meters and duck underwater, and under-18s need a parent with them or a signed parental form
• Guided sessions from age 9 in raft, kayak, hydrospeed or stand up paddle, booked ahead by phone; renting a boat without an instructor is for over-12s
• Summer paddle mornings for ages 6 to 9 on calm water, every Wednesday in July and August

Parc des Eaux Vives is a 350-meter artificial whitewater river with class II rapids, just across the French border from Basel. The flow is adjustable and the obstacles movable, and a calm warm-up basin suits first-timers. Kids raft, kayak, ride hydrospeed boards or stand up paddle with the park's instructors, then use the return channel to get back to the start. The Timonerie clubhouse sits by the course.
