Very long hike, which requires good physical fitness. To save time, it is recommended to take the bike up to Möslalm and then continue on foot to the Hoher Gleirsch.
From the Scharnitz Nature Park Info Center, follow the Hinterautalstraße to the Gleirschhöhe. There take the turnoff to the right into the Gleirschtal. First the road leads downwards, before it goes steeply upwards over the so-called "Krapfen". Continue a few kilometers into the valley until you reach the Möslalm junction. Shortly before the Möslalm, turn left and follow the forest path to the Hoher Gleirsch signposts. Park your bike here and follow the narrow path. From here, walk through forest, mountain pines and over scree-rich terrain to the summit. The way back same as ascent.
