Next to the Karwendelhaus begins the marked trail to the Birkkarspitze, which is initially quite steep and in places rope-secured in the rocky terrain through mountain pines and avalanche barriers up. Somewhat less steep, the route then heads in a southeasterly direction into the seemingly endless Schlauchkar. The route leads past the junction to the Hochalmkreuz (left) and the junction to the Brendelsteig (right). Here you keep the direction and climb somewhat laboriously - partly in rocky terrain and in unpleasant scree - up through the cirque. The cairns also provide orientation here. The path becomes increasingly steep, the last section to the Schlauchkar saddle runs in a southwesterly direction.
In this area, a hard snow field must be crossed most of the time, it is best to follow the footprints. From the Schlauchkar saddle (2,639 meters) then past the Birkkar hut (emergency shelter) and over the rope-secured climb in easy scrambling along the west ridge over to the summit of the Birkkarspitze (2,749 meters) with the cross. From the summit back to the Schlauchkar saddle and down to the south. First, the route descends steeply through boulders, in places
