The dive
The Koppenbrüllerhöhle is an active water cave. After heavy rain or snowmelt large volumes of water pour out and the mountain 'roars'.
Profile and sections
The Koppenbrüllerhöhle is an active water cave. After heavy rain or snowmelt large volumes of water pour out and the mountain 'roars'.
Since 1910 it has been Upper Austria's first show cave, and since 1973 a Naturdenkmal within the Hallstatt-Dachstein World Heritage site. Linz cave divers found new passages in 2010–2013.
Practical: cave divers dive here, among other times during an Austrian cave club's annual meeting at the end of January, outside the tourist season.
- Depth and profile
- First sump at the end of the show-cave section: ~1 h dive to its end and back · a 100 m sump was passed in 1968/69 · Krakensiphon ~200 m · also Bocksee and Pollaksiphon · depth not published · cave ~4–4.5 km
- Configuration
- Rebreathers (KISS) have been used here. All gear goes in through the show cave: compact and light is an advantage. Cave temperature ~7 °C.
- DPV: Not DPV-suitable (estimate)
- Long carry through the show cave and sumps of up to ~200 m: a scooter gains little (estimate).
Who can dive where
- At least Full cave
- Configurations: Backmount / twinset / Sidemount / CCR / Small cylinders / no-mount (speleo sumps)
- Configuration unknown — research beforehand
- Experienced divers only
