Walk inside a glacier waterfall at Trümmelbach
Ten glacier-fed falls inside the mountain, carrying meltwater from the Eiger, Mönch and Jungfrau down through a corkscrew gorge. Up to twenty thousand litres a second, and you walk in beside it.
Trümmelbach is the only glacier waterfall in Europe that is inside a mountain and accessible. The water has cut a spiral shaft through the rock over millennia; a tunnel lift built in 1913 takes you up into the middle of it, and galleries and stairs let you follow the falls up and back down.
It drains a glacial basin of about twenty-four square kilometres and carries something over twenty thousand tonnes of rock debris a year with it. Standing beside it, the sound is physical rather than loud, and the spray is constant.
The Lauterbrunnen valley outside holds seventy-two waterfalls in total, including Staubbach, which drops nearly three hundred metres in a single free fall down the cliff behind the village.

Wet, cold and loud — by design
Meltwater peaks on warm afternoons in high summer, which is when the falls are at their most violent. Inside it is cold, the spray is continuous and the steps are wet metal and stone: a waterproof layer and shoes with grip. The site closes over winter. Not suitable for anyone unsteady on stairs.
