386m, 19 pitches. Park in Breglia and walk to the Rifugio Menaggio. From there bear left on a level path to a col - cross this and continue around the mountain until the base of the via ferrata is met.
The climb is either on rock or hauling up chains - there aren't many ladder rungs, so it is fairly tough for this sort of thing. The gear is all good (2011). The good Italian site mentioned below grades this as D (so I've given it a middle 3 grade).
