A huge area of vineyards just south of Vienna - lovely to walk through in early autumn. Don't miss to go to one of the "Heurigen" in Guntramsdorf itself after the hike, and enjoy the fresh "Sturm" (slightly alcoholic grape juice)
Easy to reach by car, or also by public transport by using the "Badner Bahn" to either Guntramsdorf (closer to the "Heurigen" or "Neu-guntramsdorf" (closer to the vineyards).
