This is the run we treat ourselves to once or twice a year. It's a fairly big, steep climb that'll access a short section of trail with the perfect angle, framing, and view to the Mönch and Jungfrau. Pause your watch, stand and stare. Yes, it's that image above.

The Trümmelbach Falls themselves are inside the cliff you'll be passing by and only partially visible where the trail crosses a narrow gorge. The river is inside the limestone walls where it has carved a passage. If you randomly hear voices but see nobody, it's tourists inside the walls on viewing platforms. Carry on, you have work to do. 

Once at the top of the climb, an entirely runnable descent awaits through the forest to Wengen, one of Lauterbrunnen's car free villages. From there a shockingly steep dirt road back to Lauterbrunnen.
