The Sigmund Thun Clam Valley is one of the most famous landmarks in the Austrian city of Kaprun, because the waterfall flowing from the top of the valley to the bottom is an unparalleled sight. The height of the waterfall inside the valley is 30 meters, and the length of the road through the area to reach the waterfalls is approximately 320 meters . In the year 1890, pioneer Kaprun Nikolaus Gassner was commissioned to develop a road from the top of the valley to the bottom, so the magnificent wooden stairs were built, which became one of the most important features of the area.
