About Lysaker River

Dating back to the 12th century, several mills and manufacturing facilities used the Lysaker river for power. In modern times, the river divides Oslo and Bærum municipalities. Its source is Bogstadvannet situated at 145 meters above the ocean and its mouth is at the Lysakerfjorden, which is part of Oslofjorden. There are several waterfalls and small rapids, Granfossen is the most notable waterfall, situated near downtown Lysaker. The path is continuously hilly and varies in elevation throughout the trip, all while surrounded by a thick spruce forest.

There are plenty of spots to rest close to the water. Near the beginning of the river there’s a gapahuk, a structure intended for temporary residence or for socializing. There are also wooden swings before you reach Granfossen. Towards the end of the trip, the path is not near the river, but you will see the river when it meets the sea.


Public transportation is the easiest for this trip, if you’re not taking a round trip. Take the T-bane to Røa, then transfer to Bus 32 and get off at Bogstad Camping. You’ll start the trip a little south of Bogstadvannet. You can also either start or end the trip in Jar. The path takes you right past the Jar T-bane stop. Finish the trip at the sea, which is a 2 min. walk from Lysaker station.
