Key facts at a glance
The Sigmund-Thun-Klamm in Kaprun is an impressive water gorge that you walk through on safe wooden walkways and bridges. The route takes around 1 hour and is open from May to October – a popular family excursion.
Where the Kapruner Ache rushes down into the valley carrying glacial meltwater from the Hohe Tauern, it has carved a wild gorge over thousands of years: the Sigmund-Thun Gorge. Elaborately built wooden walkways and bridges lead right into the thundering natural spectacle – a refreshing excursion destination right next to Kaprun that offers welcome coolness, especially on warm summer days.
Wooden Walkways Through the Gorge
Over a length of around 320 metres and more than 30 metres deep, the trail winds along the rock walls. Purpose-built wooden walkways and bridges lead over the foaming water; allow about 30 minutes of walking time to pass through. Everywhere the water roars, splashes and glistens – an experience for all the senses.
A Gorge With History
The gorge was first opened to visitors back in 1893, based on plans by Nikolaus Gaßner, and named after the Salzburg provincial governor Sigmund Graf von Thun. After the walkways were abandoned in 1938, the wooden gorge trail was faithfully rebuilt in the early 1990s.
Klammsee Lake at the Upper End
At the upper exit of the gorge awaits the idyllic Klammsee reservoir lake. A relaxed circular trail, a Kneipp water-therapy facility, a playground and the inviting Klammseestüberl make this reservoir the perfect spot for a break – with views of the water and the surrounding mountains.
An Experience for the Whole Family
The Sigmund-Thun Gorge is a popular destination for families: children marvel at the power of the water, and the trail is easy to manage on foot. Because of the wooden steps, however, the gorge is not suitable for strollers or wheelchairs.
Atmospheric Events
In summer, special events transform the gorge into a magical setting: the Klammlichter (Gorge Lights) with atmospheric illumination, the Klammfrühstück (Gorge Breakfast) in the morning, and the Sagenhafte Nacht des Wassers (Legendary Night of Water) let the gorge appear in a whole new light.

- Wear sturdy, non-slip footwear – the walkways can be damp.
