An ascent of the Rastkogel as an Alpine mountain hike along the normal route, which is the easiest one, takes about 3 hours, approaching from the north along the southeast ridge (Südostgrat) from the Rastkogel Hut (2,117 m). Another route runs from the Weidener Hut (1,799 m) to the northwest over the Haslspitze and the west ridge (Westgrat) taking a good four hours to gain the summit.
