4.5 Hours ... that's what it said when we started our hike towards Trifthütte. Six and a half hours later we finally made it after  showers, fog, and snow. It was still snowint a bit when I went to bed way before 9PM that evening - way, way eralier than I normally go. The next morning we still had fog when we got up but then the sky cleared and we got a spectacular view onto the glacier. The hike also included a walk over the "Triftbrücke", a 170 meters suspension bridge, which was fun to cross (both with fog and sunshine).
