Großes Fenster, Beach and bay area in Nikolassee, Steglitz-Zehlendorf, Germany.

The Großes Fenster is a bathing bay with a beach on the Havel in Berlin, set in the bend of the Große Steinlanke just before Schwanenwerder island, on the southern Havelchaussee. At this point the Havel is at its widest, and the view reaches as far as Berlin-Wilhelmstadt.

The Große Steinlanke was designated an EU bathing site on the Havel, and the bay takes its name from the broad view it opens toward Berlin-Wilhelmstadt. The DLRG Berlin maintains one of its 26 water rescue stations here, and the Wassersportgemeinschaft am Großen Fenster e. V. and Segelschule Hering lie just to the south.

The bay lies on the Havel, not a lake, at its widest point near Schwanenwerder. South of the bathing spot are the Wassersportgemeinschaft am Großen Fenster e. V. Berlin and the Segelschule Hering, so sailing boats and school craft are part of the scene.

The bathing spot has its own car park and its own bus stop, served by line 218 and also named "Großes Fenster". It lies on the southern section of the Havelchaussee, in the bend of the shore of the Große Steinlanke just before Schwanenwerder island. A DLRG Berlin water rescue station is based here, one of 26 in the city.

At this bend of the Große Steinlanke the Havel reaches its widest extent in Berlin, and the view runs as far as Wilhelmstadt. The bay is one of 26 water rescue stations run by DLRG Berlin, and the bus stop outside is itself named "Großes Fenster" (line 218).
