Hinterreintalschrofen, Alpine summit in Bavaria, Germany

The Hinterreintalschrofen is a 2,669 m peak on the Teufelsgrat, the east–west main crest of the Wetterstein Mountains, which here forms the border between Bavaria's Reintal to the north and Tyrol's Gaistal to the south. Its high rock face drops into the Reintal and shapes the Wetterstein as seen from the north. The neighbouring peaks are the Hochwanner (2,746 m) to the west and the Hundstallköpfe (2,533 m) to the east.

The first ascent is disputed: Hermann von Barth recorded reaching the summit on 1 September 1871, while Stefan Beulke attributes the first climb to A. Heinrich and F. Henning in 1897. The peak sits on the Teufelsgrat, the ridge that forms the border between Bavaria and Tyrol.

The Teufelsgrat crest runs exactly along the state border: the south side lies in Tyrol's Gaistal, the north side in Bavaria's Reintal. The Gaistal side is served by three alm huts — Gaistalalm at 1,356 m, Rotmoosalm and Hemermoosalm at 1,417 m — traditional alpine pasture bases used by climbers.

Climbers access the mountain from Rotmoosalm at 1,810 meters and follow a route through rock gullies and scree slopes. This path demands basic climbing skills and secure footing on exposed terrain.

The Teufelsgrat crest runs exactly along the state border: the south side belongs to Tyrol's Gaistal, the north side to Bavaria's Reintal. The summit is rarely climbed despite its height of 2,669 m, and the neighbouring peaks are the Hochwanner at 2,746 m to the west and the Hundstallköpfe at 2,533 m to the east.
