Book an Interrail journey in 5 steps: choose your pass type, plan routes with the Rail Planner app, and reserve seats for high-speed and night trains.

Regional trains in Europe are cheap and scenic. Germany's Länder pass costs just €22 for unlimited travel in one state. Eurail and Interrail both work.

Book European train tickets 3–9 months early for the best prices — Vienna to Budapest starts at €9. Youth, senior and group passes save up to 25%.

A Eurail Global Pass pays off for 5–7+ cross-country journeys in 1–2 months. Point-to-point tickets are cheaper if you book 2–3 months ahead with fixed dates.

High-speed trains (TGV, Eurostar, AVE) and night trains require seat reservations — book 3–6 months ahead. Regional trains usually don't need one.

Eurail is for non-European residents; Interrail is for Europeans. Both cover 31 countries. The key difference is eligibility and home country rules.
