What does the rule "participants will, as a basic rule, travel by rail" mean?
This rule means that the travel tickets that are bought by the DiscoverEU travel team are as a standard, train tickets. There are exceptions, ferries and buses can also be booked in certain cases.
If you decide to book a flight from Madrid to Amsterdam by yourself, to then proceed to travel with an Interrail Pass from Amsterdam, that's fine.
Ferries & busses
- A ferry to cross the water,
- A bus in case the fixed travel tickets are not in budget via rail, but an existing bus service can get you to your destination.
- When you are living in an outermost region or your country is an island.
