You’re standing on a platform in Berlin. The air smells like ozone and cheap coffee. You have a backpack that’s slightly too heavy and a digital pass on your phone that says you can go basically anywhere in Europe. This is the reality of it. People talk about "interrailing" like it’s some mystical rite of passage or a confusing relic from the 70s, but at its core, interrailing what is it is just a massive, coordinated agreement between 33 different countries to let you sit on their trains without buying a dozen different tickets.
It's freedom. Mostly.
Sometimes it's also sprinting across a platform in Milan because your connecting train was delayed by four minutes and the next one doesn't leave for three hours. It’s a paradox of extreme planning and total spontaneity. You can wake up in a hostel in Budapest and decide, on a whim, that you’d rather have dinner in Vienna. Since the Interrail Pass covers the fare, you just hop on.
The Boring (But Necessary) Logistics of Interrailing
The concept started in 1972. Back then, it was restricted to travelers under 21. Now? Anyone can do it. There is no upper age limit, though the "Youth" discount (for those under 28) is significantly cheaper than the "Adult" or "Senior" fares. If you’re a legal resident of Europe, you buy an Interrail Pass. If you’re coming from outside Europe—say, the US, Australia, or Japan—you buy a Eurail Pass. They are essentially the same thing, managed by the Eurail Group G.I.E. based in Utrecht.
Don't let the marketing fool you into thinking it's a "golden ticket" that opens every door. It covers the base fare. On many high-speed lines, especially in France (the TGV), Italy (Frecciarossa), and Spain (AVE), you still have to pay for a seat reservation. These can range from a few euros to over twenty. If you forget this, a conductor in a very sharp uniform will give you a very sharp fine. Honestly, the "reservation culture" is the biggest shock for newcomers who expect to just wander onto any train they see.

Regional Differences You’ll Actually Notice
Eastern Europe is the budget traveler’s dream for this. In countries like Romania, Poland, or Hungary, your pass goes incredibly far because reservations are either non-existent or cost about the price of a candy bar. The trains might be older. You might find yourself in a compartment that looks like it hasn't been updated since the Cold War, but there's a charm to the rhythmic clacking of the wheels against the tracks that you just don't get on a silent, sterilized high-speed line in Germany.
The "Global Pass" is the big seller. It covers all 33 countries. But there are also "One Country Passes." If you just want to see every inch of Italy, getting a dedicated Italy pass is often way more cost-effective than the Global version.
Why Interrailing What Is It Matters in 2026
We live in an era of flight shame and agonizing airport security lines. Taking a train isn't just about the environment, though that's a huge perk; it's about the "middle" of the journey. When you fly from London to Prague, you see a departure lounge and an arrivals hall. When you interrail, you see the Swiss Alps from a panoramic window or the rolling vineyards of the Rhine Valley.
The infrastructure is changing, too. The Nightjet network, operated by ÖBB (Austrian Railways), has seen a massive resurgence. You can board a train in Brussels at night and wake up in Berlin or Prague. It saves you the cost of a hostel night and maximizes your daylight hours for exploring. It's not always luxury—some of the older couchettes are cramped—but the new Generation Nightjet trains are basically rolling boutique hotels.

The App vs. The Paper Pass
Most people go digital now. The "Eurail/Interrail Rail Planner" app is where you'll spend half your life during the trip. You log your journeys there, and it generates a QR code for the ticket inspector.
- Pro tip: The app works offline for searching schedules, which is a lifesaver when you're stuck in a tunnel or a station with no Wi-Fi.
- The Paper Pass: You can still get the physical paper folder. Some old-school travelers love it for the nostalgia, and it never runs out of battery. However, if you lose that piece of paper, your trip is over. There are no replacements.
- Battery Management: If you go digital, carry a high-quality power bank. If your phone dies and you can't show your QR code, you are technically traveling without a ticket.
Dealing With the "Interrail Stress"
It isn't all sunsets and baguettes. There will be moments where you’re exhausted. You've missed a connection in Cologne and the next train is packed, meaning you have to sit on your suitcase in the vestibule for four hours. This is part of the experience. It teaches you resilience.
Specific routes are notorious for being busy. The "Golden Pass" route in Switzerland or the trains connecting Amsterdam to Paris are almost always full in the summer. If you’re traveling in July or August, you absolutely must book your reservations weeks in advance. If you’re traveling in October? You can usually wing it. The shoulder season is arguably the best time to go because the weather is still mild but you aren't fighting a thousand other backpackers for the last window seat.
What about the UK?
Since Brexit, there's been a lot of confusion. To be clear: the UK is still part of the Interrail scheme. Your pass works on LNER, Avanti West Coast, and even the tiny regional lines in the Scottish Highlands. The only catch is the Eurostar. While the Eurostar is included in the pass, the pass-holder seats are strictly limited. They sell out weeks or even months in advance. If you’re planning to start your journey in London, book that Eurostar seat the second you buy your pass.
Breaking Down the Costs
Budgeting for this is tricky because the pass is only one part of the equation.
- The Pass: Anywhere from €200 to €900 depending on duration.
- Reservations: Budget around €10–€15 per travel day just in case.
- Food: Grocery stores are your best friend. A baguette, some cheese, and a bottle of water in a French supermarket cost €5. A meal in a dining car will cost €25.
- Accommodation: Hostels are the standard, but don't sleep on "pensions" in Eastern Europe which can be cheaper than a dorm bed in Paris.
Hidden Gems for the Rail Traveler
Most people do the "Banana Route"—London, Paris, Amsterdam, Berlin, Prague. It's a classic for a reason, but it's crowded.
Try the Bernina Express route through the Swiss Alps into Italy. It’s a UNESCO World Heritage site and honestly looks like a fever dream of snowy peaks and turquoise lakes. Or head to the Balkans. The train from Belgrade to Bar in Montenegro is frequently cited by experts like Mark Smith (the "Man in Seat 61") as one of the most beautiful journeys in the world. It crosses 435 bridges and goes through 254 tunnels. It's slow, it's often late, and it is absolutely spectacular.
The reality of interrailing is that it’s a lesson in geography. You start to understand how the mountains of Slovenia bleed into the plains of Austria. You notice the architecture change from the red bricks of Northern Europe to the white stone of the Mediterranean.
Actionable Steps for Your First Trip
If you're ready to stop reading and start booking, here is the sequence you should follow to avoid the most common headaches.
First, download the Rail Planner App before you even buy a pass. You can use it to see which routes require reservations. This will give you a realistic idea of the "hidden costs." If every train on your dream route has a little "R" icon next to it, you know you'll be spending more on top of the pass price.
Second, check the Seat61 website for specific country guides. Mark Smith is the undisputed king of European rail travel, and his site provides the most granular detail on everything from how to find your platform in Naples to which side of the train has the best views on the Rhine Valley line.
Third, buy a high-quality, 40L to 50L backpack. Do not take a suitcase with wheels. European cities are filled with cobblestones, narrow staircases, and ancient elevators that don't work. Lugging a 20kg rolling suitcase over the bridges of Venice is a special kind of hell that you want to avoid at all costs.
Fourth, book your "anchor" cities. Choose three major stops where you definitely want to stay and book those hostels or hotels in advance. Leave the gaps between them flexible. This gives you a safety net while still allowing for that "let's see where this train goes" magic that makes interrailing what it is.
Finally, always carry a physical "emergency kit": a printed copy of your passport, a portable charger, and a few high-protein snacks. Train delays happen. Strikes happen (especially in France). Having a granola bar and a charged phone makes a three-hour wait in a cold station feel like a minor inconvenience rather than a disaster.
Europe is waiting. The tracks are already laid. You just have to get on the train.
