If you really want to arrive with style, you can consider making your Trondheim visit a unique holiday. The Coastal Express (Hurtigruten) is called the most beautiful sea voyage of the world and takes you into the many Norwegian fjords before arriving Trondheim. You could start south from Bergen or north from Tromsø. Both would be a three days journey to Trondheim. Please plan well in advance.
