Interrail is about freedom and exploring Europe in an unconventional way. It’s not always about passing the capitals and biggest cities of Europe. In the spirit of this mindset, we introduce a route sweeping a bunch of, what we call, ‘second cities’. These underrated cities are often overlooked, but they have so much to offer. This route will start off in Hamburg and head West through the overlooked cities of The Netherlands, Belgium, and West Germany. You will return to Hamburg at the end of the journey knowing that many countries are more than just their capitals.


Hamburg - Bremen - Utrecht - Antwerp - Gent - Lille - Maastricht - Cologne - Hamburg
