Grunewald is a German forest located in the western side of Berlin on the east side of the Havel, mainly in the Grunewald locality. At 3,000 hectares (7,400 acres) it is the largest green area in the city of Berlin.
The forest occupies, on the western side, 3/4 of the Grunewald locality, a small portion of the southern part of Westend (both in the Charlottenburg-Wilmersdorf borough); a great part of Nikolassee, the northern side of Zehlendorf and the northwestern part of Dahlem (all 3 in the Steglitz-Zehlendorf borough). It is close to the border of the neighborhood of Wannsee and its lake, and is near the Düppel forest. It is divided by the Havel river from the localities of Kladow, Gatow and Wilhelmstadt (all in the Spandau borough). It also borders the locality of Schmargendorf.
There are two islets located by the Havel (Lindwerder and Schwanenwerder) and a small peninsula (Schildhorn); and the tallest point is the hill of Teufelsberg, which is 117 metres (384 ft) above sea level. On the northern border is found the Funkturm Berlin (radio tower) and the Messe Berlin (the trade show).
Beyond the river Havel and part of the Großer Wannsee lake, the forest is rich in lakes and ponds. The biggest are the Schlachtensee, Krumme Lanke, the Grunewaldsee and the Hundekehlesee. These lakes are located on the western borders of the forest and are linked by a canal. The other lakes are the Riemeisterfenn (between Krumme Lanke and Grunewaldsee), the Teufelsee  (in central-north area), and Pechsee and Barssee (both in the middle of the forest).
The natural environment of the Grunewald is forest, mainly composed of conifers and betulaceae. Some areas are forbidden to visitors as nature reserves (Naturschutzgebiet) to protect the local fauna (especially amphibians and birds).
The border of the Grunewald can also be reached by several other S-Bahn stations : Berlin Nikolassee (S1 + S7), Berlin Schlachtensee (S1), Berlin Heerstraße (S3 + S75), Berlin Pichelsberg (S3 + S75). The southeastern borders are linked by two U-Bahn stations: Krumme Lanke and Onkel Toms Hütte (both on U3 line).
