Tannegg Castle Ruins

Highlight • Castle

There is not much left of the castle ruins, but the wall is still impressive and, above all, the path over the Tannegger Grat is an absolutely beautiful rooty and cool ridge path. Is worth a trip!

Nice spot with a bench and a fireplace. The signage saying "To the castle ruins" is a bit misleading, because as others have said, nothing of the ruins can be seen anymore.

The Tanneggergrat S3-4 (from the ruins of Tannegg) is completely unsuitable to life-threatening for bikes (downhill), uphill anyway.
