Oberstdorfer Hammerspitze, Mountain summit between Allgäu Alps, Germany and Austria

The Oberstdorfer Hammerspitze is a 2,260-metre summit in the Allgäu Alps, located northwest of the Fiderepass and the Fiderepasshütte and southeast of the Walser Hammerspitze. No marked trail leads to the top; climbers reach it along the connecting ridge from the Walser Hammerspitze, where climbing difficulties of grade II must be mastered, or from the Fiderepasshütte at grade III.

Until July 2013 the peak was called Hammerspitze in Oberstdorf usage and Schüsser in Kleinwalsertal usage, and German and Austrian maps labelled the two neighbouring summits in opposite ways. The official renaming made the German Hammerspitze the Oberstdorfer Hammerspitze and the Austrian Schüsser the Walser Hammerspitze, partly to avoid confusion in emergency calls. An 1844 boundary description already recorded the name Schisser, called Hammerspitz on the Vorarlberg side.

The two names reflect the language border: Walser German "Hammer" means rock, while the Allgäu dialect "Schisser" means "the one throwing stones", still found in the Schißer Kar in Warmatsgund. The 1844 border description records "Schisser" for the whole ridge between Kanzelwand and Fiderepass, called Hammerspitz on the Vorarlberg side.

The routes to the summit are unmarked and lack safety installations, requiring experience and proper Alpine climbing equipment. Beginners should hire a local mountain guide or join guided tours to ensure safety.

The peak is known for its raw Alpine setting where climbers must navigate without marked trails or safety infrastructure. These unmodified conditions make it a demanding destination for experienced mountaineers seeking authentic climbing challenges.
