It is around 4 km long and is named after Johann II of Liechtenstein who had the walkways installed in 1875.
[citation needed] The waters of the Großarler Ache, a mountain stream, formed the gorge over thousands of years.
In 1875 work began by members of the Pongau Alpine Club to make the gorge accessible, but was not completed due to a lack of funds.
Prince Johann II of Liechtenstein, who ran a hunting lodge in the nearby Großarl, donated 600 guilders for an expansion of the work.
At the completion of work in 1876 the gorge was renamed to honour the donation from the Prince.
