Schwarzbachfall-Höhle, cave in Austria
The Schwarzbachfall-Höhle is a water-filled cave on the eastern slope of the Göll massif in Salzburg, with its entrance at 580 meters elevation. The cave supplies the Gollinger waterfall and maintains a constant temperature of about 5 to 6 degrees Celsius year-round.
The cave has been explored by divers since the 1960s, who reached depths of up to 60 meters. For a long time, people believed the water came from Königssee, but modern geological studies revealed it flows from an underground karst spring system within the Göll massif.
The cave entrance is visible from the Gollinger waterfall area but is not open to regular visitors, as the site is protected and occupied by water. You can observe the waterfall and surrounding landscape from nearby hiking trails, which offer safe access to view this natural protected area.
Water flow from the cave varies dramatically with the season, from just a few liters per second in winter to 20,000 liters per second during floods. This extreme change reveals how the underground water system responds to weather and snowmelt from higher elevations.
