Stop in Trondheim
Trondheim is a small town north of the city of Oslo. Rather far is only a night train. It 'a very nice town with nice people very friendly. Not much to see in the classic sense of the city of art. But nature takes over and it is beautiful around. So many colorful houses, many rivers and forests in which walks and excursions.
Excellent hostel in Trondheim now also for families with children with you. E 'un poso where you can do a good lap and put it in a tour of Norway can not be like the final destination of the trip.
Good trip to Norway.
