Do you want to experience the white waters in a more wicked way? Bellyak is an adventurous water activity where you are prone on the board with fins on your feet for propulsion and steering. There is only a board between you and the river's rapids and rocks, so this is one of the most extreme activities on the river. The minimum age for this activity is 12 years.   Since this activity is weather/water level dependent, you only need to book a spot on the trip. To book this activity, you only pay a deposit of 12,5€ per person. The rest is paid on the spot to the guides.
