Lysakerelven

Lysakerelven (also known as Lysakerelva) is a river that forms the boundary between the municipalities of the capital city of Oslo and Bærum.

The river by this name has its source in Bogstadvannet, though the source is further up, at Langlivann, and Søndre and Nordre Heggelivann in Oslomarka, the forests surrounding Oslo. Consequently, it is considered part of Oslomarkvassdragene, the river system flowing through these forests. It flows out into Lysakerfjorden, part of Oslofjorden near Lysaker.

The river is 7.4 kilometres (4.6 mi) long, with a total fall of 145 metres (476 ft). It includes several smaller rapids and waterfalls, the most prominent of the falls being Granfossen, earlier known as Fåbrofossen. In later years, the area around the river has been developed as a recreational area, and a footpath follows the entire length of the river.
