The water-bearing Koppenbrüller Cave is located in the valley and can be accessed via a short walk along a secure trail by the charming Koppentraun river. Admire dripstone features which date back thousands of years and listen to the crashing of the invisible brook inside the mountain.

A visit to the Koppenbrüller Cave, the youngest of the 3 Dachstein caves, offers an impressive insight into the underground waterways of the inside of the Dachstein.

Especially during snowmelt and heavy rainfalls you can observe a unique natural spectacle here, which you can hike through in complete safety on one of our guided tours. 

The water crashes its way through the mountain - no wonder that there are so many myths surrounding the Koppenbrüller cave. 

You can explore the "wild" side of the cave in one of the trekking tours for the whole family. Take the child-friendly short adventure tour or the challenging trekking tour "Urwassergänge"along the original waterways, you'll feel like a real explorer!

From the restaurant 'Koppenrast'  at the end of village Obertraun, a comfortable footpath leads along the Traun to the cave entrance (approx. 15 minutes). The entrance of the cave is a karst source, which only occasionally overflows out of water, especially after heavy very rainfall or snow melt. 

Inside the cave, brooks are constantly in flow. During the 50 minutes guided tour guests gain insight into the development of the caves and can see for themselves how the dry stream bed in the ‘Simonyhalle’ is transformed into a crashing brook in just a few minutes during times of heavy rainfall or snowmelt.

Past the ‘Niedrigen Versturzhalle’ and ‘Hannakluft’ abyss, you will reach the origin of the cave brook – the lake 'Bocksee'. On the way back, you can see dripstones and wall calcite which have formed over the centuries.
