Torstein, Mountain summit in Dachstein Massif, Austria

Torstein is a mountain summit in the Dachstein Massif, situated where Upper Austria, Styria, and Salzburg meet at an elevation of about 2,948 meters. The terrain features limestone formations that attract climbers and hikers exploring the region.

Jakob Buchsteiner, an imperial hunter known as Jackl, made the first documented ascent in August 1819, solo, during a land survey. His route from Windlegerscharte circled the Gosau Glacier and reached the summit via Untere Windlucke. The first woman to climb the 1,000-metre south face was Fritzi Gruber on 30 July 1946.

The Torstein's south face, about 1,000 metres high, is the tallest wall in the whole Dachstein massif, and climbers have used it since the early 20th century; Fritzi Gruber made the first female ascent of it on 30 July 1946. The peak lies on the Salzburg–Upper Austria border, and the nearest village is Filzmoos, about 5 km to the south-west.

The normal route starts from Untere Windlucke and climbs the southeast ridge at UIAA grade II. Climbers use the Seethalerhütte (2,740 m) to the east or the Adamekhütte (2,196 m) to the north as bases. The south face, about 1,000 m high, has routes up to UIAA VI A2. The summit lies on the Salzburg–Upper Austria border, about 5 km from Filzmoos.

The south face of Torstein drops about 1,000 metres, the highest wall in the whole Dachstein massif. The first woman to climb it was Fritzi Gruber, on 30 July 1946. The normal route now reaches the summit via the southeast ridge from the Untere Windlucke at UIAA grade II.
