Like an enormous wedge, the Lopper mountain chain separates the main basin of Lake Lucerne from Alpnachersee. Before the road and railway were cut into the vertical rock walls, Rengpass was the only link between Lucerne and Obwalden. Today, the pass has become one of the most popular bike loops of central Switzerland.
