Eurail vs Interrail — what's the difference?
The passes cover the same trains but target different travellers. Interrail is for European residents (EU and most European nationals). Eurail is for everyone else — visitors from North America, Australia, Asia, and beyond. The coverage and prices are almost identical; the only practical difference is eligibility. If you hold a European passport and live in Europe, get Interrail. Otherwise, get Eurail.
Which pass type should you buy?
Both Eurail and Interrail offer two main structures:
Global Pass — unlimited travel across 33 countries. Choose between a continuous pass (e.g. 15 days, 1 month) or a flexi pass (e.g. 10 travel days within 2 months). Flexi passes suit most travellers since you'll spend several nights in each city.
One-country Pass — good if you're focusing on a single large country like France, Germany, or Italy.
For a classic multi-country trip (Paris → Amsterdam → Berlin → Prague → Vienna, for example), the Global Flexi Pass with 10 days of travel within 2 months hits the sweet spot.
Building your route
The biggest mistake first-time rail travellers make is cramming too many cities into too few days. A good rule of thumb: spend at least 2 nights in each city, and no more than 4–5 destination cities in a 2-week trip.
Think in terms of geography first — travel broadly in one direction rather than backtracking. A westward loop (Paris → Amsterdam → Berlin → Prague → Vienna → Venice → Barcelona) is exhausting but doable in 3 weeks. A tighter arc (Amsterdam → Cologne → Basel → Milan → Florence) is far more enjoyable in 10 days.

What do you need to book in advance?
Your pass covers most journeys but not all. Some trains require a seat reservation on top of your pass — this is especially common on:
- - High-speed trains: Eurostar (London–Paris), TGV (France), AVE (Spain), Thalys/Eurostar (Brussels–Amsterdam), Frecciarossa (Italy)
- - Night trains: ÖBB Nightjet, Trenhotel (Spain)
- - Scenic routes: Glacier Express, Bernina Express
Reservations cost €3–€15 per segment and are booked through the national rail operator or the Eurail/Interrail app. Book these as early as possible in summer — popular TGV trains sell out weeks ahead.
Practical tips before you go
Download the apps: Rail Planner (official Eurail/Interrail app) lets you add journeys offline. Useful when you have no signal at a station.
Validate your pass: From 2023 both passes are digital — activate it in the app on the day of your first journey.
Travel on overnight trains when possible: A night train between two distant cities saves a hotel night and a travel day. The ÖBB Nightjet network now covers Vienna–Brussels, Vienna–Rome, Vienna–Barcelona, and Hamburg–Zurich among others.
Don't over-plan: Part of the joy of a rail pass is spontaneity. Lock in the first 2–3 nights of accommodation and your high-speed train reservations; leave some days open.
