From Gasthof Unterreith at the Fageralm valley station you walk across the practice meadow to the edge of the forest and then follow the edge of the slopes of the ski path from the Fageralm. During the ascent to the mountain station of the Forstaubahn (you cross under it a few times) you also cross the valley run a few times - caution is advised!
From the Forstaubahn mountain station, follow the Jägerlift Skiweg to the right of the Jägerlift valley station and then - roughly - the summer hiking trail no.2 until you reach the extensive alpine pasture area of the Fageralm at the Unterbergalm. Past the Lechneralm and the Premhütte you continue to climb until you reach the route of the summery Fagerstraße, which you then follow to the Trinkeralm. From there it is another 100 meters and half a kilometer to the Hinterfager mountain station and the Goliath giant swing, where you have reached your destination.
The descent takes place along the ascent route or along the Forstau valley run.
