Willi Huttig was a keen mountaineer. For the Starnberg section of the Alpine trail in 1968, as its first chairman, he acquired a high-alpine hut, the Hohenzollernhaus at 2123 m. After negotiations with the main committee of the Deutsche Alpenverein (DAV) and its Berlin section, the Starnberg section was able to purchase the Hohenzollernhaus in 1978, and after renovations made it the first DAV hut and a vital asset in mountain rescues.
