Through the unlit (and not signposted) tunnel to the south of the tennis courts (overview panel), then along the east side of the tennis court wall. From there descend and traverse, alternating between sections of rock and others of earth. The exposure slowly increases and soon the first key point is reached reached: a passage about 600 metres vertically above the Lauterbrunnen Valley with its cable car station and parking lot - here is nothing but iron bars and a lot of air under the soles.... And on it goes, sometimes on the cliff face itself and sometimes in the forest, all the way along the Mürrenfluh. A short, vertical ladder provides variety, as does the rather wobbly three-cable bridge over the Mürrenbach. At the same place is a 60-meter-long Tyrolienne, which can only be done in the company of mountain guides ("closed" sign, so choose the right branch at the junction). Before and after the Sinterbach are several passages with more ladders, which are partly vertical; the exposure, however, is small. Another short three-cable bridge over a canyon provides for a further variety. At about 1300 metres you have reached the lowest point of the via ferrata. And soon the finale comes: an 80-meter-long suspension bridge, which is very shaky and has no continuous tensioned cable, to clip into. The safety cable available, is indeed quite movable and fixed only on every fourth suspension device. However, the suspension bridge can also be avoided (if you're a wimp), by turning right and moving up onto the normal footpath between Mürren and Gimmelwald. After the suspension bridge the via ferrata is over, only the short ascent to the Gimmelwald cable car station (1363 m, 3 hours) is missing.

Short and straightforward.
