The Alpeiner Kräulferner, a glacier on its north flank, gives the Östlichen Seespitze a much wilder appearance than from the south.

The easiest ascents up the Östliche Seespitze run over glaciers and require the right equipment and experience.

This route runs initially westwards over the Hochmoosferner glacier and then up the southwest flank to the summit, requiring block climbing of moderate difficulty (UIAA grade I).

More difficult and one hour longer is the ascent from the Franz Senn Hut over the Alpeiner Kräulferner.

The crossing to the Westliche Seespitze is difficult and, at one point, is assessed as UIAA grade III.
