Speiereck, Mountain summit in Mauterndorf, Austria.

Speiereck is a 2411 m summit at the southeastern end of the Radstädter Tauern, where the Hochfeind ridge terminates. Its south flank drops in a single broad slope of about 1360 m to the Murtal near Sankt Michael im Lungau. The summit lies on the eastern edge of the Tauern Window, so Bündnerschiefer, Wettersteindolomit, Lantschfeldquarzit and Paragneis succeed one another here.

Winter sports tourism began developing on this mountain from the mid-20th century onward. The construction of lifts and ski runs marked a turning point in how people used these slopes.

The name Speiereck refers to the peak itself, while the Großeck below it carries a radio transmitter and directional relay that links via the Plattenspitze to the Rossbrand in the Pongau. Walkers reach the Peterbauernalmstube at 1910 m by the Sonnenbahn cable car from St. Michael; the Speiereckhütte of the Austrian Tourist Club stands at about 2066 m on the Großeck's east side.

This peak is most accessible during the snowy season and offers longer ski descents for those with experience. Visitors should prepare for changing weather conditions at this altitude above 2400 meters.

A descent from the summit down to the Sonnenbahn valley station stretches over 8 kilometers with a vertical drop of around 1300 meters. This lengthy run ranks among the longer ski runs you can find in this region.
