For some reason this local gem is not in the Lonely planet. The hill, which requires approximately…read more1-1.5 hour hike one way, is a fantastic escape to the nature!
The trail up goes mostly through the forest, however, once you get to the top, a fantastic view on Oslo will reveal itself!
As this was my first time, I didn't find any specific path, just went up, till some kind soul advises me to follow blue marks on the trees, which you can do both on the way up and down.
