[2] For the 1936 Summer Olympics, the city hosted the canoeing and rowing events at the regatta course on the Langer See.

Located in the south-eastern suburb of Berlin, Grünau is bounded (in south-west) by the Brandenburger town of Schönefeld (in Dahme-Spreewald district).

The Berliner bordering localities are Bohnsdorf, Altglienicke, Adlershof, Köpenick, Müggelheim and Schmöckwitz.

The quarter is surrounded by the Berliner Stadtforst and traversed by the river Dahme (tributary of the Spree) in the southern shore.

To cross the river Dahme, it is served by the BVG ferry line F12[3] in Wassersportallee, that links Grünau to Köpenick.
