Very long hike, which requires good physical fitness. To save time, it is recommended to take the bike up to Kastenalm and then continue on foot to the Hallerangeralm.
Starting at the information centre Scharnitz at car parking Länd follow the road towards the Isarlodge Wiesenhof. Continue on to Gleirschhöhe where you take the forest track to your left towards the source of the river Isar. Just before the Kastenalm park your bike and cross over a little bridge.Then go up a steep track past the Lafatscher Niederleger to mountain meadows Halleranger. When you reach the pastures the path splits, left to the hut Hallerangeralm.
