From the turn-off to Schöneben in the open field, we turn left, parallel to the forest path, to the Hauserbauerhütte. There we keep slightly to the left and, after a short steep climb, reach the Zirbeneck. We follow the ridge (summer trail markings) into the gently undulating terrain to the tree line. From there, we continue along the ridge to Sandkogel and over the shoulder to the summit cross of the Greim.
The descent follows the same route as the ascent.
