Klaas
"A fun experience for novice rafters on a partly rippling, partly gently undulating river with some light swells where the water flowed into the boat. The guidance and instruction (in German) is excellent. My children aged 8 and 10 enjoyed doing it, with my ten-year-old saying afterwards that he also enjoyed a little more challenge. It is indicated that it is already doable for three-year-olds, but I consider it too heavy and mobile for a three-year-old, at the earliest a large five-year-old in my opinion."
