Grinzing lies in the northwest of Vienna and, with an area of 613.52 hectares, is the largest suburb in the district of Döbling. Grinzing is characterised by numerous forested ridges of the Wienerwald. Grinzing’s woods are home to several streams, including the Schreiberbach, which runs untouched through the Wildgrube almost as far as Nussdorf. The Reisenbergbach begins to the west of the Reisenberg and makes its way through Grinzing, where it flows into a canal. The headwaters of the Arbesbach also lie in the west of Grinzing. A further notable characteristic of the area is its grapevines, especially on the Reisenberg and Hungerberg hills.
