The starting point is the P5 car park at the Znachtal junction in the rear Weißpriachtal valley, which is easily accessible by car or valley bus (toll road – coin and card payment possible). The hike leads along gravel path no. 770 past the Granglerhütte (1,320 m) to the ‘Ulnhütte’ fork (valley bus stop). Behind the hut, turn left, pass the roaring waterfall and cross the Longa. After approx. 200 m, a marked hiking trail leads to the Tonimörtlhütte hut. Once you have reached the hut, continue straight ahead and then turn left at the Wirpitschsee lake (1,699 m). The marked trail now continues to the Twenger Almsee lake (1,699 m).
