The Holmenkollen Ski Jump, perched on a hilltop overlooking Oslo, offers a panoramic view of the city from the top of the jump tower and the chance to zip-line down from the ski-jump platform. During Oslo's annual ski festival, held in March, Holmenkollen draws the world's best ski jumpers. Even if you're not a daredevil ski jumper, the complex is well worth a visit thanks to its ski museum and a couple of other attractions.
Admission includes entrance to the ski museum and the ski-jump tower. The Kollensvevet Zipline is not included and not covered by the Oslo Pass. There's a funicular-style lift to the ski-jump platform and a few more steps to the main viewing platform at the very top.
To get to the museum, take T-Bane line 1 to Holmenkollen and follow the signs uphill.
