The Trümmelbach Falls are the world's only glacier waterfalls that are accessible underground by lift, galleries, tunnels, paths and platforms. They alone carry the meltwater of the glaciers from the Jungfrau down to the valley - up to 20,000 liters of water per second. The water carries with it over 20,000 tons of boulders and scree per year and causes the entire mountain to shudder and make a thundering noise.
The Trümmelbach Falls are part of the Lauterbrunnen Valley's 72 waterfalls
