Copenhagen to Berlin

Hi,

The most direct and easiest way to go from Copenhagen to Berlin is by way of Hamburg Hbf. Buy a ticket Copenhagen-Hamburg Hbf, the border crossing into Germany is at Puttgarden. In Hamburg Hbf take the train to Berlin Hbf. Both legs are direct and on the ICE trains..

I just had dinner 2 nights ago with someone who flew into Copenhagen just to take the train-ferry to Hamburg. She enjoyed it. You ride the train onto and off of the ferry.

Thank you Fred and Chani! Can anyone else help answer my questions?

If the Deutsche Bahn sells you a ticket from Copenhagen to Berlin, you've got a ticket from Copenhagen to Berlin. In the past I've bought tickets from www.bahn.de to Germany and back from different neighbouring countries. These are international trains, operated in cooperation with the respective railway companies. Both companies can sell the tickets.
You buy a through ticket, including the ferry. Actually, as noted above, the train goes on the ferry.
If the young one travels free on the train, she's also free on the ferry. You'll get a ticket on which the number of travelling persons is mentioned. That one of them is travelling free, only shows in the price.
One important thing: you must have the credit card ready with which you've bought the ticket. The ticket collector will probably ask for it. It functions as an ID.
Have a good trip!

I don't know if you've checked out the budget European airline fares, however it's possible to fly from Copenhagen to Berlin on EasyJet starting at $25 for one way flights early morning. And it's a 1 hour flight.
I'm okay on short train trips, but when they get almost 400 miles and require a ferry crossing--I'm flying.
And the best part is that you have an additional day in your trip.

Nicely sitting on a train, looking at the landscape, doing some reading about your next destination, is no lost time.
