The normal route for the easiest ascent of the Kellenspitze runs up the northwestern mountainside from the col of Nesselwängler Scharte. The base for this route is the Tannheimer Hut at 1,713 metres. From the hut the ascent heads steeply uphill to the north across the scree slopes of the Gimpelkar cirque to the col, then right and upwards requiring climbing at UIAA grade I and, in places II. There are also short sections of cable protection. According to the literature this approach takes a good 2 hours to reach the top. From the opposite side, a route runs from the Otto Mayr Hut in the north up to the same col, taking a good four hours to the top of the Kellenspitze.
