10. Top of Tyrol (Austria) The observation deck atop Stubai Glacier in Tyrol, Austria, looks like a perilous high-dive platform at an altitude of 10,500 feet.
The Top of Tirol has a unique position that offers a breathtaking 360 degree panorama that stretches from the Zillertal and Stubai Alps to the Dolomites and Chalk Alps.
The project idea is similar to the Grand Canyon Skywalk.
