The Lauterbrunnen Valley has many famous waterfalls.

Switzerland's wildest glacier canyon and the largest subterranean waterfalls are not visible at first glance.

The ten cascades of the Trümmelbach near Lauterbrunnen, Switzerland are hidden behind rock walls.

In earlier times, when they were not yet accessible, one only heard the eerie drumming in the bowels of the mountain.

Today, this natural wonder is accessible by means of an elevator, galleries, tunnels, trails, and platforms.

Once inside, one can admire the melting snow waters of the Eiger, Mönch and Jungfrau that come crashing down thunderously.
