You don't need to be a train aficionado like Sheldon Cooper, but let's be honest: Once in a while, travel connoisseurs like you and me - we love to skip the quick, cheap flights to get from A to B. We prefer to travel overland. There are three reasons why this excursion starts in Hamburg, Germany (Hamburg Central Station). Firstly, you are already quite far north when you arrive in (very well connected) Hamburg, almost like knocking on Scandinavia's door. Secondly, on your first leg to Copenhagen (Denmark), you will board the ferry by train. Boarding a ferry by train does not happen too often on this planet, making it a legitimate "Check. Done that!" item on the overland traveler's bucket list. The cruise from Puttgarden (Germany) to Rødby (Denmark) will take 45 minutes. You can choose to stay on the train or explore the ferry, perhaps to do some duty-free shopping. This option comes in handy in case you forgot to buy some proper beer in Hamburg, which, of course, is reason number three to start your trip there in the first place.
