Day 2: First, ascend to the Seescharte (gap at 2,762 m a.s.l.), which can be reached from the Sulzenau Hütte via Grünausee (lake) or from the Nürnberger Hütte on a winding path. Afterwards the path leads from below the Gamsspitze across chunky rocks to the beginning of the glacier (at about 3,160 m a.s.l.). Hike across the ridge to reach a snowfield at about 3,340 m a.s.l., where you then walk on to the ridge leading to the peak of the Wilder Freiger. You will pass a small tollhouse made of stone.
Descend the same way, that you ascended.
