Gjønnes is the district southwest of Presterud, Nadderud and Bekkestua, south and east of Haslum, north of Ekeberg, Ramstad and Ballerud.
Geographically, the most significant feature of Gjønnes was the Nadderud Watershed (Norwegian: Nadderudvassdraget), with several small creeks from northern Bærum converging south of Gjønnes farm before continuing southwest towards Øverlandselva.
[4] Farming later decreased significantly, and the periphery of the farmland was soon built up with housing.
[7] On the other side of the school is found the headquarters of Haslum's sports team Haslum IL; a small complex with two football fields (bandy during the winter) and an indoor hall mostly used for handball.
[8] Before 1973, Stabæk IF operated a small ski jumping hill named Gjønnesbakken.
Norwegian National Road 160 passes through the area, with the Bekkestua Tunnel having its western exit right by the Metro station.
