1d
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 gorge is 320m long and up to 30m deep. The route continues past the gorge to the clear Klammsee lake, which offers a circular walking path and views of the surrounding Hohe Tauern peaks.
Mission Directive / X-Factor
“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.”
Hazard Assessment
No significant objective hazards under normal operating conditions. Gated, secured boardwalk.
MITIGATION: Hold children's hands on the walkway; wear shoes with some grip for wet wood.
