Climbed twice with skis (Jan 24, and Feb 13, 2006).
A short ski-tour (Jan 24, 2006) from Grafenmatt after spending most of the day on the ski pistes (returned the same way). Magnificent sunset ! Skied down in almost complete darkness, what an experience!
Second time (Feb 13, 2006) I also climbed via Grafenmatt (started in Fahl); after summiting Herzogenhorn continued to nearby located Silberberg (1358 m). Silberberg's N-NW face is quite steep (40-45°) and fun to ski down!
