FATMAP difficulty grade
You go from the inn in the Au (1265m) in the Zillergrund over the bridge and then south uphill past the Jagdhaus into the Sundergrund.
On the wide alpine pasture path you go up through the forest into a valley step. Afterwards you pass the Rachhüttenalm and continue (a little ascending).
On the other side of the stream you will see a hiking destination, the Kainzenhüttenalm at 1550m. Same way back!
