Interrail is the classic way to see Europe by train on a single ticket. One pass gives you unlimited rail travel across 33 European countries for a set price, which makes it one of the cheapest and most flexible ways for students and young travellers to cover a lot of ground.
Rather than booking each leg separately, you pick a pass that suits your trip and hop on trains as you go. Interrail rewards spontaneity, keeps costs predictable, and lets you swap short-haul flights for a slower, greener journey through the continent.
