The Barmsteine are two rock towers, 841 and 851 metres above sea level, in the northernmost part of the Hasel Mountains in the Bavarian Alps.

Geologically, the pinnacles have given their name to the so-called Barmstein limestone (Barmsteinkalk), a turbidite sequence which is part of the Oberalm Formation in the Upper Jurassic rock layer.

Both rock pinnacles are a popular destination, especially for climbers because they are lit by the sun until late in the evening and are easy to get to.

In January 2008 the southern face of the Small Barmstein was put out of bounds to climbers by the owner, who built a fence here after numerous infringements of the climbing rules.

Even during the Nazi era the Barmsteine were visibly and invisibly used: in addition to the use of the hidden galleries as a site for the armaments industry, a large, white swastika was painted on the rocks so that it could be easily from the direction of Austria; this was even before the Anschluss of Austria to Germany.
