After leaving the Hallerangerhaus, you follow trail 224 heading west, forming the sixth stage of the Karwendel High Trail. (Detour to Sunntigerspitze mountain: follow the sparsely marked trail leading north from the Hallerangeralm.)  You pass the Kohleralm pasture hut and soon come to the Lafatscher Niederleger hut before making a somewhat more steep descent on the road down into the Hinterautal valley. You can reach the Kastenalm mountain hut by taking a brief detour at the marked junction in the road. From here, you keep heading along the road out of the valley and pass the source of the Isar river on the way. This is followed by a gentle ascent to the panoramic Gleirschhöhe (1069 m) and a leisurely descent that takes you past the Wiesenhof Lodge. You then come to the Isarbrücke bridge and subsequently complete the route in Scharnitz. After a short rest, you can pick up your well-deserved goodybag at the nature park information center with a full stamp pass.
