What to expect at the Trümmelbach Falls
The Trümmelbach Falls are very imposing and powerful waterfalls between Lauterbrunnen and Stechelberg. They move up to 20'000 liters of water per second during the melting of snow or glaciers. You can experience them between April and September.
In ten cascades the water comes through a narrow gorge, which is partly without daylight. Therefore, the Trümmelbach Falls are also called underground falls. In total, the water falls down about 140 meters.
The catchment area of the Trümmelbach covers about 24 km². In addition to water, more than 20,000 tons of bedload come along from the glaciers every year. The huge glacier walls of Eiger, Mönch, Jungfrau and Lauberhorn are drained in this way.
The water has eaten through the rock for 15,000 years and thus created the gorge.
The Trümmelbach is part of the UNESCO World Natural Heritage Swiss Alps Jungfrau-Aletsch. It is one of the 72 waterfalls in the Lauterbrunnen Valley.
