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.

Facts about the development

After the discovery of the Trümmelbach Falls in the 19th century, they were gradually made more and more accessible to visitors.

  • 1886: Inauguration of the stairs and bridges at the lowest falls
  • 1916: Construction of the tunnel lift as a funicular with counterweight for access to the top three falls
  • 1986: Completion of the upper tunnel staircase with gallery and lookout gallery
  • 1990: Connection of the lower with the upper part of the gorge and access to three more falls and wild rock formations

In total, the Trümmelbach Falls have been developed to 600 m.

Activities at the Trümmelbach Falls

You can visit the Trümmelbach Falls, because the gorge is walkable. You reach the top three waterfalls via a tunnel lift. The lack of daylight is replaced by lighting. The Trümmelbach Falls are the only walkable underground waterfalls in Europe.

You walk on secured wooden paths and footbridges over rock galleries or along them. Tunnels and bridges have also been integrated into the path. At viewing platforms you can observe the thundering waterfalls. Large information boards give you a good overview of the individual cascades.

The tunnel lift has an inclination of 45 degrees and needs about one minute for the 105 m length. With it you can climb 100 meters inside the gorge. A maximum of 40 people can fit into its cabin.
