Located in the Lauterbrunnen Valley, the creek called Trümmelbach alone drains the glacier defiles of Eiger (3967 m), Mönch (4099 m), and Jungfrau (4158 m) and carries more than 20,000 tons of boulder detritus per year.[1]

Its drainage area is 24 square kilometres (9.3 sq mi), half of it covered by snow and glaciers. The falls carry up to 20,000 litres of water per second.[1]

After the hamlet of the same name on the valley floor the Trümmelbach feed into the Weisse Lütschine, which heads north through the valley and the village of Lauterbrunnen further down to join after 7 kilometres (4.3 mi) its sister river, the Schwarze Lütschine at Zweilütschinen, where they join to the Lütschine.
