Airwalk - an exceptional view

This opportunity is one you won't have often: to stand on a glass surface with an unobstructed view 200 m straight down into the abyss, and all around a breathtaking view of the high alpine landscape of the Upper Tauern mountains.

Only on the Airwalk can you experience all facets of the Kölnbrein dam's architecture: when the wall curves over your head and the massive body made of 2 million m3 of concrete spreads out before you - incidentally nearly the volume of the Cheops pyramid (2.6 million m3).

An aerial adventure of a different kind

Deep within Austria's largest dam

At 200 m height and 626 m width, the Kölnbreinsperre Dam is Austria's largest dam. During peak times, 200 million m3 of water are dammed up behind it, enough to fill bathtubs for 1.4 billion people (20% of the world's population).

The technical data is monitored daily at 2,500 measuring points. During a dam tour, you have the opportunity to learn more about electricity generation and get to know the inside of the dam.

Tours take place every full hour (10 a.m. to 5 p.m.) and last approx. one hour. The meeting place is directly at the shop in the Berghotel Malta, where you also get the tickets. We request that you notify us in advance of groups of 15 or more persons.
