In 1877 - 1886 the lowermost falls were rendered accessible by flights of steps and bridges. The tunnel lift, which from the technical point of view is a funicular with a counterweight, was constructed in 1913, at the same time as the access to the 3 upper falls. The flight of steps at the top of the tunnel, the gallery and lookouts were built in 1986.
The lower part of the gorge was connected to the upper half during the winter of 1990. From the interior of the mountain, rugged rock formations and 3 additional falls became visible.
With that, it is now possible to walk along some 600 metres of path in the Trümmelbach Gorge. The way has been opened to 10 falls; the difference in height between the lowest and the highest fall is 140 metres.
The tunnel lift is 105 metres long and rises about 100 metres, so that its gradient is approximately 45 degrees. It can carry about 40 persons and the journey takes 60 seconds, i.e. the capacity is about 500 persons per hour. The energy-saving counterweight is as heavy as the cabin would be if it held about 15 persons. The walls and roof of the cabin are made of glass. The lift was constructed in 1983, and is the third one since the original construction in 1913.
400 meters of galeries, 5 tunnels, 30 meters of bridges, 16 flood lights, 32 spot lamps.
All the work was done with the greatest care and in such a way as to minimize the human impact on the surroundings, or even to render it entirely invisible, in order to emphasize the grandiose natural beauty of the falls. That is also why the shafts of electric light are directed solely at the walkways, rocks and water.

In the precipitous sides of the gorge, which are virtually inaccessible to man, one finds primeval mountain woodland with Alpine roses, rare ferns and lilies. In cold rainy weather and in winter this provides shelter for ibex and chamois.
Trümmelbach is included in the Federal Inventory of Monuments and Landscapes of National Importance.
