This hike started at P.1860 Chalchtrittli, following the marked trail up to Muttseehütte (mountain lodge), and then to Kistenpasshütte (another mountain lodge). From there almost straight up to Muttenbergen P.2895 and P.2905. There was perhaps 10 cm of snow, but no ice where I went, so it was possible to hike without crampons....
