What are the best transport options to travel between european countries?

I'm planning to travel to europe in April 2009. I would like to know what are the best options for me to travel from London-%26gt;Amsterdam-%26gt;Copenhagen-%26gt;Munich-%26gt;S鈥?Which route is best by air and which are best by land/sea? I only have 6 weeks to travel to the cities I have mentioned above, so basically 1 week in each destination.|||As an addition to Becca's good answer, there is also the option of the bus/coach.

If you will stay about a week in each destination you are likely not cheaper off with a rail pass.


For cheap rail tickets, 3 months or 2 months before travel the best deals can be had.


One of the most useful sites for train travel with Germany involved is:

For cheap flights you can use many different sites. I normally use one of the general sites to find which company offers the best deal and then search for a direct link to that company:

That said, some of them are really nice (I like the German ICE trains). Another way to get about is low fair european airlines. I know of Easyjet and Ryanair, but there are others as well. I've flown with RyanAir before and enjoyed it. They sometimes have limited destinations, but you can find very cheap tickets.
