The Rietzer Grießkogel may be reached from the north from the Peter Anich Hut (1,909 m), which lies above Telfs to the south. Path no. 153 runs in a southerly direction initially over the Bachwandkopf peak, then along the west arête to the summit in, according to the literature, 3½ hours. From the south it takes about 4½ hours on the path from Kühtai or Haggen in the Sellrain valley along the Zirmbach stream and up the southwestern flank of the mountain. This ascent is also one of the most popular ski tours of the region. Another path runs from Flaurling via the Flaurlinger Alm from the east to the top.
