The district of Kjelsås offers ski jumps, slalom slopes and vast areas of woodlands for hiking. Lake Maridalsvannet, located close to the woodlands, provides Oslo with its drinking water and is also the source of the Akerselva river, (formerly Frysjaelven).

Kjelsås is situated in the part of Oslo often not defined as "west" or "east" side but somewhere neutral in the middle.
