Series of waterfalls in Lauterbrunnen

Trümmelbach Falls

Explore Trümmelbach Falls, Europe's largest underground waterfalls in Lauterbrunnen Valley.

Tucked away in the Lauterbrunnen Valley, Trümmelbach Falls power through the mountains, showcasing nature's strength. Fed by the melting snows and glaciers above, these falls carry the waters from the Eiger, Mönch, and Jungfrau mountains, providing a spectacle for visitors.

As you journey to Trümmelbach Falls, the air fills with the sound of rushing water. These falls are the largest subterranean waterfalls in Europe, accessible by a tunnel-funicular built over a century ago. The series of ten glacier-fed cascades plummet down at a rate of 20,000 liters per second, cutting a path through the rock.

The journey through the caves is auditory and physical; the echo of water and the feel of mist on your skin connect you to the ancient landscape. While the falls are lit to improve visibility, the darkness of the caves adds mystery to the experience. Visitors can explore various viewing platforms for different perspectives of water moving through the mountain.

The falls are a visual wonder and an important natural force, continuously changing the mountain's interior. The strength of the water is evident in the smoothed rock surfaces and deep crevasses shaped over millennia. Trümmelbach Falls can be safely enjoyed via well-maintained paths and tunnels.

While summer brings the highest flow due to snowmelt, Trümmelbach Falls remain a sight to see throughout the open season, from April to November. Dress warmly, as cave temperatures can be low, regardless of the weather outside. Note that some stairs are involved in the visit.
