Depart early morning on Deutsche Bahn Intercity-Express (ICE) or EuroCity (EC) train to København. This transit takes approximately 4.5 to 5 hours and crosses the scenic Fehmarn Belt by ferry connection or tunnel depending on the service provider.
Continue your journey immediately by taking the Swedish SJ high-speed night train or daytime trains connecting København to Oslo Central Station. The journey typically takes around 8 hours, passing through picturesque Swedish countryside.
Take the NSB (Vy) train from Oslo Central Station to Trondheim Central, an approximately 6.5 to 7-hour scenic ride through the lush Norwegian landscape featuring fjords and mountains.
Board a direct flight (approximately 2h) from Trondheim Airport to Tromsø Airport for the fastest and most convenient transfer northwards as no direct train line exists to Tromsø.
Depart Bergen by Vy train to Oslo (about 7 hours), then continue from Oslo to Hamburg by train (about 12 hours) or train + overnight sleeper service via Copenhagen for efficient rest.
