Just wanted to see suggestions for can't miss destinations when visiting Norway on a family trip?
We visited Trondheim for a weekend in December and it was lovely! There are plenty of walks, skiing nearby, and some beautiful tourist attractions to see.
This is what we did: http://www.neverendinghoneymoon.net/trondheim-norway/
Bergen! Such a nice city. If your family is adventurous, you should also spend a night at Memurubu turisthytte AS. It's crazy-beautiful there. Most people take the boat out, spend the night and hike back (about 8 miles) the next day. I suppose you could take the boat out and back, but the hike is spectacular.
My wife and I did it opposite: Hike out, boat back. I think the other way is better.
