Fantastic way to start our first trip to Oslo. We took the T-bane to Holmenkollen and took a slow walk up a fairly steep hill, taking in the view as we walked. This took around 20 minutes. The entrance to the museum, jump tower and zipline is on the north side of the jump, just follow the signs. There is a great view of the jump itself and auditorium from this route. I agree with another reviewer - if you suffer from vertigo (the actual condition or a fear of heights!) then this is quite steep, especially on the steps down. Otherwise there is a barrier to lean on. There is a great museum leading you towards the jump tower that’s well worth looking at, including 5 models of the ski jump as it has evolved over the years. There is a lift up to the jump tower. As you get out of the lift, the zipline is to the right and to the left a great view of the jump, plus steps up to the very top. Beautiful views over Oslo and the surrounding hills. The worst bit for vertigo sufferers (I have the condition, where a turn of the head can cause room spin) is descending the stairs from the top to the floor below - all you can see is the jump below and everyone I saw was walking very slowly! Brilliant visit, I didn’t realise this was on my bucket list! Hope to return to do the zipline!
