Trümmelbach falls

The Trümmelbach Falls are the only glacial waterfalls in the world that can be reached underground using a lift, galleries, tunnels, pathways, and platforms. They alone transport up to 20,000 liters of water per second of glacial meltwater from the Jungfrau down to the valley. Over 20,000 tons of stones and scree are transported by the river each year, causing the mountain as a whole to tremble and roar.

The Trümmelbach Falls is one of the 72 waterfalls in the Lauterbrunnen Valley, which also includes the massive Staubbach Falls. Water gushing from sheer rock cliffs that are several hundred meters high can be seen on the hiking tour from Lauterbrunnen to Stechelberg, which is mostly on level terrain.

Its drainage area is 24 square kilometers, with snow and glaciers covering half of it. Following the same-named hamlet on the valley floor, the Trümmelbach feed into the Weisse Lütschine, which travels north through the valley and through the nearby village of Lauterbrunnen before joining its sister river, the Schwarze Lütschine, at Zweilütschinen, where they join the Lütschine, after 7 kilometers.
