The Aare Gorge is an almost 700 ft. deep gorge created over the course of millennia as the Aare River gouged its way through the limestone rocks. Hardly more than a yard wide at its narrowest, would you dare cross over? Take the adventurous trail across bridges and through tunnels along the glacial currents of the Aare River, and catch your breath as you explore the exhilarating sights while the river rushes through below.
