One pass, 33 countries, 30+ operators. How Interrail and Eurail actually work — pass types, pricing, reservation rules, and when a pass beats buying point-to-point tickets.
Interrail is a rail pass that lets you travel across 33 European countries on a single ticket. Instead of buying individual point-to-point fares, you pay once for a set number of travel days within a window, and on each travel day you can board almost any participating train in any included country.
The pass was introduced in 1972, originally as a scheme for under-21s and now available to all ages. It's administered by Eurail Group GIE, a collective of European railway operators. The same product is called Interrail for residents of Europe and the UK, and Eurail for everyone else. The passes are functionally identical — different names, different buying websites.
Both are bought online directly from interrail.eu or eurail.com respectively, or through retailers like Trainline.
The flagship product. Valid in all 33 countries. Sold as either continuous (unlimited travel for a set number of consecutive days) or flexi (a set number of travel days used within a longer window).
Continuous options: 15, 22, or one month of unlimited travel. Flexi options: 4, 5, 7, 10, or 15 travel days used within a one- or two-month window.
Cheaper than a Global Pass if you're only travelling in one country. Valid for 3, 4, 5, 6, 7, or 8 travel days within a one-month window. Available for most major countries including France, Germany, Italy, Spain, and the Benelux bloc (sold as a single pass covering Belgium, Netherlands, and Luxembourg).
If you're only exploring, say, Italy by rail — Rome, Florence, Venice, Milan, Naples — the Italy One Country Pass is substantially cheaper than a Global Pass and often cheaper than point-to-point tickets if you're making 4+ long journeys.
Pass prices vary by duration, class (Standard or First), and age band. As of 2026, a typical Global Pass price range:
First Class passes cost roughly 25% more than Standard. The benefit varies by country — First Class seats are notably better on long-distance trains in France, Germany, and Italy; on most regional services the difference is marginal.
This is the single most important thing to understand about rail passes: having a pass is not always the same as having a ticket.
Some trains — most notably high-speed services and night trains — require a seat reservation on top of the pass. The reservation is an additional fee, usually €5–€35, depending on the country and service. Without the reservation, you can't board.
The high-speed service through the Channel Tunnel has a small number of passholder seats per train, and the reservation fee is €30 — one of the highest on any European route. These seats sell out quickly, especially on weekends and in summer. If you plan to use your pass on Eurostar, book the reservation as far in advance as possible (up to 4 months ahead).
A rail pass makes sense when:
You'll usually do better buying individual tickets when:
The Channel Tunnel service is the natural entry point to Interrail for UK-based travellers. Your pass entitles you to a discounted reservation (not a free seat) on the London–Paris, London–Brussels, and London–Amsterdam services. The reservation fee as of 2026 is €30 each way in Standard class.
Passholder seats must be booked via Eurostar's dedicated passholder channel, not the normal booking site. Details are emailed to you when your pass is issued.
Interrail passes are sold directly at interrail.eu (for European/UK residents) and Eurail passes at eurail.com (for everyone else). Both sites are operated by the same organisation and accept major international payment methods. Physical passes are no longer issued by default — the pass lives in the Interrail app on your phone.
Passes are sold directly by Interrail (interrail.eu) and Eurail (eurail.com), and also via resellers including Trainline, which carries both. Prices are typically identical across sellers; Trainline is convenient if you want to bundle a pass with individual reservation fees or related ticket purchases in a single place. For a first-time buyer deciding between pass types, the official Interrail and Eurail sites have the most detailed product information.
