Trummelbach is the place in Switzerland where you can watch a waterfall inside a mountain!
20 km from Interlaken, Switzerland, is 'Trummelbach' where you can watch the glacier waterfalls finding their way through the mountains before jumping out of the mountain heights as a waterfall.
The Swiss have built a tunnel lift inside the mountain which carries you to the top where the glacier melts of Eiger, Monk and Jungfrau enter the mountain crevices. The well illuminated stairways with landings constructed at vantage points, enable the tourist to watch the path of the waterfall inside the mountain. The roar of 20,000 litres of water per second carrying boulder debris takes one close to raw nature.
