From Kogleralm, a green-and-white-marked trail initially leads us steeply over alpine meadows and then through forests, partly steep, for about 1 hour upwards to the distinctive trail junction below the Reißthalerhütte (unmanaged).
Here, we do not follow the trail straight uphill (Gretchensteig), but instead turn left, walking more flatly, where after a few minutes, we reach the somewhat hidden Reißthalerhütte.
From there, the trail ascends again, veers right from the forest road, and leads us in numerous switchbacks, and finally through somewhat stony terrain to the base of the Raxenmäuer (entrance to the secured Reißthalersteig, memorial plaque).
Here, we turn left onto the blue-painted footpath trail (the trail is partly hard to recognize) until, after about 5-10 minutes, we see a rock with the old inscription "Amalienst" in a recess in the wall.
Now, climb directly upwards over some grassy rock (caution when wet!) and slightly to the right (old blue markings) over gravelly ledges (UIAA grade I) into a shallow gully. Continue upwards through the gully (do not veer left, as further up the ridge-like rock ledge becomes impassable), always following the blue markings until a rocky rise.
Climb over this (UIAA grade I - II) and from here, head slightly left to the plateau.
In a few minutes, reach the impressive summit marker on Heukuppe at 2,007 meters – a magnificent panorama awaits us.
Descent via the Karl Ludwig Haus (managed) and either the Gretchensteig or the Reißthalersteig back to Koglergraben and the starting point.
