Start at 'Innsbrucker Huette' following the path to the 'Bremer Huette'. Leave that marked path after having passed the ridges coming down from the Habicht and at 2400 altimeter turn right (NW) direction the hardly existing 'Glaetteferner' (small glacier nearly entirely coverd by stones now). We initially planned to do the full ridge from 'Aeußere Glaettenieder' as described in the guide book, but this was only reachable by climbing rotten rock once covered by the shrunk glacier.
So better directly turn directly to the south slope of´the Habicht. There is more than one way, but the easiest route is a bit left finally reaching the ridge leading to the summit. It is not the best rock but you don't need a rope if you are familiar with climbing UIAA II. Best descend is the normal route (NE) to 'Innsbrucker Huette'.
Crampons and axe might be usefull depending on conditions.
If you have information about this route that doesn't pertain to any of the other sections, please add it here.
