The Kaunergrathütte is a really nice mountain hut. The ascent from Plangeros is very demanding and demands a lot of fitness. Another approach goes over the Cottbusser Höhenweg. Songs, the old way is blocked by rockfall and you must first descend a bit again to then get on the normal climb from Plangeross. Unfortunately, the remaining 600 Hm still go strong in the legs.
