This medium-difficult hike takes us up the Sonnberg to the exciting Filzalmsee. From the Hochbrixen Gondola car park we initially walk in the direction of the church, after the carpentry firm turn left and follow the road to the Gasthof Nieding, where we take a short break on the beautiful sun terrace. Then we continue our hike, about 200m, until we reach the Filzalmsee.
