The Glocknerblick viewing platform is one of Stubnerkogel's engineered alpine viewpoints, built for the moment when the Gastein mountains open out and the Grossglockner appears on the horizon. It is a simple idea, but in clear weather it works beautifully.
Use it as part of a Stubnerkogel outing rather than as a separate destination. Combine the platform with the suspension bridge, short ridge walks, or ski-area lifts, and check visibility before spending money to go up.
