Aquatic sports in Flims

10,000 years ago, 100 billion cubic metres of rock thundered into the valley. Known as the Flims Rockslide, this event created the Ruinaulta, a canyon-like gorge in the Anterior Rhine Valley that can be reached on foot, over water, by train or by bike.

The popular rafting tour takes you through the impressive Vorderrhein canyon, one of the most popular white water stretches in the Alps.
