Holmenkollen hill on the west side of the city is famous for the enormous ski jump that can be seen from just about everywhere in Oslo. The most popular sports arena in Norway, Holmenkollen also contains the world's oldest Ski Museum and an exciting ski-simulator (on which visitors can try out the Holmenkollen ski jump themselves!). Holmenkollen hosts a variety of winter sports events, culminating in the annual ski festival in March. Even those not interested in winter sports should not miss the chance to enjoy the spectacular panoramic view of the city.
