If it is your first time or you are a permanent water rafting fan, it is not every day you can experience the waters of Rhein river. Splash yourself in the ultimate adrenalin rush in a rafting bonanza time.
If you concentrate on rafting or the sightseeing around Cologne offers beautiful views all the way round, just make sure you stay firmly seated in your boat so you will not face the water from too close up. Water on your face and hands if fine, there are certain doubts about any more than that, stay leveled at all times.
