In reply to UKC Articles:
Worth pointing out that if you'll be in the valley for a few days you can get a monthly valley transport pass for about 69 francs.
With that you can take all cable cars, trains and buses between Lautterbrunnen and Stechelberg (horizontally) and up to Gimmelwald/Murren from Stechelberg and Grutschalp/Murren from Lauterbrunnen on that side of the valley, and Wengen up the other side, for a full month.
Definitely good value not just to go to the crag but also to visit towns, go to shops, go for walks and sightseeing, etc. when not climbing.
ETA: You need a photo to get the pass, so take one with you if you planning on it
