Roter Stein, Mountain summit in Lechtal Alps, Tyrol, Austria

Roter Stein is a 2,366-metre summit in the Lorea group of the Lechtal Alps in Tyrol, Austria. The easiest route climbs from Berwang via the Gröbener Älpele and the west flank in about two and a half hours; the Füssener Weg, a secured and marked path built in 1911, reaches the top from Bichlbächle on the east side.

The rocky formations developed over millions of years through Alpine tectonic processes that shaped its current structure and elevation. These geological forces also created the characteristic landscape of the surrounding Lechtal Alps.

The name Roter Stein ("Red Stone") refers to the reddish rock of the summit, which lies in the Lorea group of the Lechtal Alps as classified in the 1981 Alpine Club guide. The main valley base is Berwang to the east; the hamlet of Bichlbächle is another starting point for ascents.

The easiest ascent starts in Berwang via the Gröbener Älpele and the west flank, taking just under two and a half hours. From Bichlbächle, the marked Füssener Weg on the east side is secured and also takes about 2.5 hours. A third route climbs from Fernpass through the Kälbertal, joining the Füssener Weg higher up, and takes around 3.5 hours.

The easiest route, from Berwang via the Gröbener Älpele and the west flank, takes just under two and a half hours; the secured Füssener Weg on the east side from Bichlbächle also takes about 2.5 hours. The first documented ascent was made by a man named Vogl in the 1840s for the geognostic-mining society of Tyrol and Vorarlberg.
