Holmenkollen Skimuseum og hopptårn

Kongeveien 5, 0787 Oslo

The world's oldest ski museum sits inside the ski jump itself at Holmenkollen, with 4,000 years of skiing history, polar gear and a ski simulator where children can 'ski' downhill and jump. The same ticket takes you up the jump tower, 64 metres above ground, with a 360-degree view over all of Oslo. In summer there's a zip line from the top.
