Ecotrail Oslo 21 km is the best way to explore how fantastic it is to combine urban paths with closeness to the city, nature and the sea.

From Fossum by the lake Bogstadvannet the path follows the fascinating Lysaker river down to the fjord and the city. 

From Lysaker  you´ll run by fjord all the way to the finish line. You will pass the wonderful Vækerø park and the country side of Bygdøy.

The last 5km by the fjord is on asphalt.

The very last kilometer goes over the old fort called Akershus Festning and to finish at the pier called Vippa.
