Now the Holmenkollen area is a perfect place hiking or mountain biking. If you have little time you can walk from Frognerseteren restaurant to the ski jump (or opposite) and then take the subway to wherever you are headed, or you can hike further north into the forest, or east, then you will end up at Sognsvann, a popular lake in Oslo. This lake is the last stop of subway line 3 Sognsvann. The best is to go the opposite way because then you can reward yourself with nice food and cakes at Frognerseteren restaurant after hiking all the way from Sognsvann. They have free maps over the area at the tourist information offices. It is also possible to visit the area by bike, there is a bike outlet at Voksenkollen (a station along the Frognerseteren subway line).
