Start your tour the same way as you would going to the Zuckerhütl, but after entering the Sulzenauferner you keep right, going to the Pfaffenkogel summit. Close to the summit there is little notch (on the left of the summit as you go up). It's pretty obvious.

If there is little snow, you can make a 15-20m rappel into the line. Bring some tat to make an anchor. In these conditions, the line is quite gnarly. Like, really narrow. And steep. Almost the whole way is around 45°, maybe a bit steeper. The only turn you will make is a jump turn. It's more like survival skiing than anything else. If that's what you want to practice, go for it. Bring an axe if you expect anything else than powder.

With more snow cover, the line can be a lot more forgiving, with more room to turn. Maybe even nice!
