Start at the center of Fieberbrunn. Drive along the river towards the inn "Eiserne Hand" and Lärchfilzhochalm. Halfway you turn right towards the alpine inn Lärchfilzhochalm (big blue sign) and follow the trail up to the inn. At Lärchfilzhochalm take the right way (easy down) towards Streuböden. Pass the alpin inn Wildalpgatterl and after about 300 m cross the meadow and turn left. The first turns down are more difficult than the rest of the trail - difficulty hard! Bike down the way "Zillstattweg" until you reach the asphalt street, here turn right towards lake Lauchsee, pass it and return to the center of Fieberbrunn.
You can bike the trip in both directions!
Restaurants: Lärchfilzhochalm, Berggasthof Wildalpgatter, buffet at lake Lauchsee
