550m height difference from kandersteg to allmenalp, it's a 350m via ferrata 3-3.5h. Level of difficulty K4 (1=easy, 5=heavy), (maybe not for beginners)

Your are absolutely exposed at the wall and the waterfalls (see pictures) the route is very diversified and you should be free from giddiness.

At the valley station you could borrow the equipment (wear good walking shoes!) theres is a ropeway to go down, a the allmenalp there is a small restaurant.

AND: The allmenalp is a good starting point to go further up to great climbing walls (e.g. Ueschenen and more) or to do a hiking tour.

You will like the view to the Oeschinensee and the Blüemlisalp :-)
