Austria's most famous alpine road climbs to 2,504 m (8,215 ft) via 36 switchbacks through the Hohe Tauern National Park, with the Grossglockner — Austria's highest peak at 3,798 m — looming over the entire route. The Kaiser-Franz-Josefs-Höhe viewpoint offers a face-to-face encounter with the Pasterze glacier.
