I'm from Oslo, Norway. If you're coming to Norway, skip Oslo. Most people get really disappointed when they come to the airport here. It isn't like the pictures at all
Go straight to Bergen and the west of Norway. That's where you find the fjords and the beatiful scenery. The north could be interesting if you'd like to see midnight sun.
I went to Svalbard (norwegian island in artica) this summer. God damn cold (freezing temperatures even in summer) but it was worth it. Daylight 24/h .. didn't change a bit at any hours. We went hikin in the middle of the night
. Great hikes, but you have to rent a gun if you leave town cause of polar bears. But that's really cheap.. about 10$ for a day. Msg me if you want to know more about Norway and Svalbard!
