You can climb up on the cable car, the schedule can be found on the official website. From Krippenstein Upper Station, you still have to walk about 25 minutes on foot.
The observation deck itself consists of five metal fingers, each have some distinctive feature, for example a photo frame or a glass floor. And the view itself is really spectacular, we recommend.
Getting there: parking at the lower station of the cable car N 47 32.895 E 13 42.378. Or take the bus to Obertraun Dachsteinseilbahn Talstation. Use route planner http://fahrplan.oebb.at.
