High rope course in Hinterglemm

High rope course in Hinterglemm, Austria

While I was walking through a valley in Hinterglemm there was a certain whirr in the sky. People crossed on a high rope course in 100+ meters high the valley. Though the people dashed down the rope on high-speed I tried to take a photo. Can you see the person near the warning element for planes? Can you imagine to do the same in this scenery?
