You start at Franz-Senn-Hütte (http://www.fankhauser.at). How to get there, is described on the Ruderhofspitze page
The marked path from the hut leads up pretty steep in northern direction. You pass the beautiful Rinnensee (lake). Then it take some easy scrambling (UIAA I), to get to the summit (some cables).
No special gear required
