Bifertenstock, Mountain summit on the Glarus–Grisons border, Switzerland.

Bifertenstock is a summit in the Glarus Alps that rises to 3,419 meters with steep rock faces on its northern side. Multiple climbing routes traverse these exposed sections, offering different levels of difficulty for experienced mountaineers.

Bifertenstock was first climbed on 7 September 1863 by the journalist Abraham Roth, co-founder of the Swiss Alpine Club, Georg Sand and the industrialist Johann August Raillard-Stähelin, with the guide Heinrich Elmer and the porters Christian Vordermann and Jakob Stüssi. Their route from the east is now the normal way, rated little difficult and taking about five hours from the Bifertenhütte.

The summit carries two names: Bifertenstock in German and Piz Durschin in Romansh, reflecting how different communities have shaped this place over time. Visitors from both language regions recognize the mountain by these distinct names.

The approach starts at the Bifertenhütte at 2,482 meters, accessible via a marked trail from the parking area at Alp Quader. The route demands proper equipment and experience with rock and ice terrain.

In June 2022, an amateur radio operator activated the summit for the first time for radio communications, establishing 43 contacts. This demonstrates how the remote peak continues to attract new types of visitors.
