Technical Summary

Formed by the Kapruner Ache river over thousands of years, the Sigmund Thun Gorge is a narrow, deep chasm in the Kaprun valley. A maintained wooden walkway (Stege) follows the rock walls, allowing visitors to walk directly above the glacial water.

The Crux

The Night Lights and the Glacial Blue. The gorge offers evening 'Klamm-Lichter' (Gorge Lights) events where the waterfalls are illuminated in shifting colours. The adjacent Klammsee’s turquoise water, caused by glacial rock flour, provides a striking contrast — and the entire experience requires almost no physical effort.

Ideal For
None. Suitable for most visitors, including families with children.
