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, in the western side, 3/4 of Grunewald locality, a little bit in south of Westend (both in Charlottenburg-Wilmersdorf borough); a great part of Nikolassee, the northern side of Zehlendorf and the north-western bit of Dahlem (all 3 in Steglitz-Zehlendorf borough). Is it not too far from the borders with Wannsee and its lake, from the Düppel forest and is divided by the Havel river from the localities of Kladow, Gatow and Wilhelmstadt (all in Spandau borough). It also borders with the locality of Schmargendorf.
In the area, by the Havel, there are located two islets (Lindwerder and Schwanenwerder) and a little peninsula (Schildhorn); and the tallest point is the hill of Teufelsberg, with 117 metres (384 ft) amsl. In the north it borders with the Funkturm Berlin (radio tower) and the Messe Berlin (the trade show).
Other than 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 linked by a canal. The other lakes are the Riemeisterfenn (between Krumme Lanke and Grunewaldsee), the Teufelsee  (in central-north area), Pechsee and Barssee (both in the middle of the forest).
The natural environment of the Grunewald shows an extended 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).
Grunewald borders could be reached also at other S-Bahn stations : Berlin Nikolassee (S1 + S7), Berlin Schlachtensee (S1), Berlin Heerstraße (S3 + S75), Berlin Pichelsberg (S3 + S75). The south-eastern borders are linked by two U-Bahn stations: Krumme Lanke and Onkel Toms Hütte (both on U3 line).
