Ascent from Weidenburg to the Zollnersee Hütte
The castle ruins are the first highlight at the start. The route then follows a somewhat monotonous but nevertheless scenic forest road to the lower Bischofalm. Excellent cheese is produced there, which you shouldn't miss out on. Further on, you hike along a path to the Obere Bischofalm and can enjoy the beautiful alpine landscape there. The Zollnersee is not directly on the trail, but a detour from the Zollnersee Hütte to the lake is highly recommended.
Alternatively, you can cycle to the Bischofalm on a mountain bike (the best place to start is at the Kronhof just above Weidenburg). You can leave your bike at the hut or cycle along the tractor track up to the Obere Bischofalm. Here again: leave your bike or take the track to the Rosseralm and on to the Zollnersee Hütte.
