LEVEL of difficulty: Initiation activity. No previous experience is necessary, and it is enough to have a normal physical form (not having problems on a physical level and doing physical activity on a regular basis). Being an aquatic activity, it is necessary to know how to swim (basic level). The activity has a relaxed development, and its intensity is low, so that all participants can enjoy. In the river basin there is no river current, so it becomes easier. Do not forget to bring a change of clothes and a towel (optional) to shower in the changing rooms.
