Ten spectacular waterfalls, fed by the Jungfrau glaciers, are located inside the mountain. A lift built into the rock leads to the entrance of the narrow galleries carved above the tortuous cleft. From here, you can enjoy the sight of the Trümmelbach falls that crash and froth through a succession of gigantic erosion holes. The falls culminate at the bottom of a well, where the upper waterfall ends its majestic course.
