Starting point and destination of this 48km hiking loop is Wergenstein. One is not only close to pristine flora, but also to a rich fauna: the Safien-Rheinwald region between Piz Beverin and Alp Alperschäli is populated by a large ibex colony with 380 animals. If you are lucky, you can observe male and female ibex and their young. The route zig-zags through naturpark Beverin up and down around the Bruschghorn and is at times quiet demanding.
