The Trümmelbach Falls at Lauterbrunnental valley are a unique natural spectacle. Through ten glacier waterfalls, Trümmelbach alone drains the giant glacier walls of Eiger, Mönch, and Jungfrau mountains. During the snowmelt, up to 20,000 litres of water per second plummet into the abyss, taking around 20,000 tons of debris with them every year.
What makes the Trümmelbach Falls so special, is its location inside the mountain. They are among the largest underground waterfalls in Europe, and the only glacier waterfalls in the world that can be accessed from underground, via a tunnel lift. In the summer, you can get really close to the roaring water masses through a narrow path and a rock gallery.
