The Rote Knopf ( m (AA)) is the second highest mountain in the Schober Group within the High Tauern in the Austrian Alps. It is only two metres short of the Petzeck, the highest summit in the Schober. Nevertheless, this peak is far less well known that the Hochschober or the Glödis. This is probably because the mountain is not visible from the valleys of the Kalser Tal or the anterior Debanttal.
The easiest ascent runs from the Elberfelder Hut following the waymarking southwards before turning west and running along the southeastern arête to the summit. This climb not only requires sure-footedness, but also exposed, albeit not difficult, climbing at grade I. From the summit, Austria's highest mountain, the Großglockner, may be seen prominently to the north.
