The route starts at the Hafelekar, which is the top station of the Nordkettenbahnen lifts and cable cars. The bottom station is located directly in the centre of Innsbruck. From the Hafelekar, take route 219 and follow it west as it leads downhill. The trail leads past Hafelekarspitze on the south side of the peak and then continues downhill for a short distance before following a level path on the southern side of the mountain. The trail then snakes its way briefly uphill before heading diagonally down into the Mühlkar corrie. Continue west below the Mandlspitze peak and then follow the trail steeply uphill to the Mandelscharte. From there, continue west again down to the Arzler Scharte.
The descent from the Arzler Scharte (route 217) follows a steep trail that leads south down a talus slope. The trail covers 1,300 vertical metres over loose Karwendel rocks and scree, requires surefootedness and is only for experienced mountain hikers who are in a good physical condition and wearing hiking boots. Upon reaching the forest, the trail continues straight down the mountain. At the next turnoff (not signposted), keep right to stay above the road and follow the narrow mountain path to the Arzler Alm mountain hut, where you can enjoy a well-deserved refreshment break. From there, it's just a short walk back to Hungerburg along a signposted mountain path.
