The extraordinary Trummelbach Falls (In German: Trümmelbachfälle), near Lauterbrunnen, Switzerland, are a series of ten glacier-waterfalls hidden inside a mountain.
The waterfalls drain the glaciers of the Eiger, the Monk and the Jungfrau mountains, which explain why up to 20,000 litres of water can rush through every second.
Trummelbach Falls is an unusual place where water itself has cut its way through the hard rock, creating deep crevices and caves. The only way to see the chutes is going on a subterranean walk through a man-made series of tunnels that let visitors see the cascades be shooting out through the confined space.
