Route: Information centre – Gleirschhöhe – Valley Hinterautal – Source of the River Isar – Alpine Hut
Kastenalm – Lafatscher Niederleger – Alpine Hut Hallerangeralm– Alpine House Hallerangerhaus
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. To the left below the alpine pasture, a small, marked trail branches off and leads diagonally upwards across the alpine pasture into a mountain pine alley. The mountain pines clear after a few hairpin bends and the trail continues across a mountain meadow to the ridge. Continue to the right over stony, rugged, steep and partly somewhat exposed terrain to reach the Sunntigerspitze. The way back is the same as the ascent.
Surefootedness and a head for heights are absolutely necessary on the last 100 hm!
