There’s something magical about traveling through Europe by train. No airport stress. No long security lines. Just the rhythmic sway of the train, sweeping landscapes out your window, and a new city every day if you want it. Interrail (or Eurail if you’re non-European) makes that kind of freedom possible.
But let’s be real—one month is both a lot of time and not enough time. That’s why having the right Interrail route can make or break your trip. The right mix of cities, countryside, culture, and downtime. And the best part? It’s all flexible. You don’t have to plan every hour in advance. Interrail gives you options to adapt your route on the go. (Perfect if you fall in love with a lakeside town in Switzerland or want to skip a rainy week in Berlin.)
In this guide, I’ll walk you through real, tested Interrail route ideas for 1 month in Europe. Whether you’re into history, beaches, nightlife, food, or all of the above—we’ve got a route that works. Think of it like choosing your own European adventure.
Before we dive in, here are a few tips to keep in mind:
Quick Interrail Tips Before You Start Planning
- Get the right pass. For a month, the best value is usually the Interrail Global Pass with unlimited travel for 1 month. (Prices vary based on age—under 27? You’re in luck.)
- Download the Rail Planner App. It works offline and shows train times, routes, and which ones require reservations.
- Some trains need reservations. France, Italy, and Spain often do. Book these early to avoid last-minute surprises.
- Travel light. You’ll thank yourself every time you haul your bag onto a train in 5 minutes flat.
- Mix big cities with smaller towns. The secret to a great trip? Balance. Cities like Paris and Prague wow you, but it’s the Alpine villages and seaside escapes that make your trip unforgettable.
Ready to see Europe one track at a time? Let’s start with the Classic Western Europe route—perfect if it’s your first time and you want to hit the big names.
Route 1 – The Classic Western Europe Loop
For First-Time Interrailers Who Want the Best of Everything
This is the most popular Interrail route idea for 1 month in Europe—and for good reason. It blends famous capitals, charming towns, and natural beauty. You’ll hit five to seven countries without ever feeling rushed.
Route Overview:
Start in Amsterdam → Brussels → Paris → Lyon → Geneva → Interlaken → Milan → Florence → Rome → Venice → Munich → Prague → Berlin → End in Amsterdam
Week-by-Week Breakdown
Week 1 – Urban Cool Meets Romance
- Amsterdam (2 nights): Kick things off in the Netherlands. Rent a bike, visit the Anne Frank House, and get lost in the canal-lined streets.
- Brussels (1 night): A quick stop for Belgian waffles, beer, and the Grand Place. Not a must-stay city, but it breaks up the journey to France.
- Paris (3 nights): The Eiffel Tower, Montmartre, and café culture await. Use the metro and take it slow—there’s a lot to soak in.
Week 2 – Scenic Routes and Mountain Views
- Lyon (2 nights): A food lover’s dream. This lesser-known French gem offers riverside walks and world-class cuisine without Paris crowds.
- Geneva (1 night): Expensive, yes. But the train ride here through the Alps is stunning. Walk by the lake and maybe splurge on fondue.
- Interlaken (3 nights): Base yourself here for Swiss Alps day trips. Take the train to Jungfraujoch or hike the Lauterbrunnen Valley. It’s the definition of postcard-perfect.
Week 3 – Italian Culture, Art, and Pasta
- Milan (1 night): Great for fashion and a quick look at the Duomo. But not a long-stay city.
- Florence (2 nights): Renaissance heaven. Climb the Duomo, eat gelato on every corner, and day trip to Pisa if you have time.
- Rome (3 nights): The Colosseum, Vatican, Roman Forum… history lives here. The train ride in is chaotic, but once you’re there, magic.
Week 4 – Beer, Castles, and Cool Cities
- Venice (1 night): Crowded, but still worth it. Especially early mornings or evenings.
- Munich (2 nights): Beer gardens, Bavarian charm, and if you’re up for it—a day trip to Neuschwanstein Castle.
- Prague (2 nights): Cobblestones, Gothic towers, and incredible value. It’s romantic and fun at the same time.
- Berlin (3 nights): Hip, historic, and endlessly cool. Street art, museums, and late-night doner kebabs.
- Back to Amsterdam (1 night): Full circle. Wind down with a final night in a city that now feels like home.
Why This Route Works
- No major time zones or jet lag.
- Trains are frequent, comfortable, and scenic.
- You get a bit of everything: capitals, mountains, history, beach (Venice), and nightlife.
- You can adapt easily if you fall in love with one place or want to slow down.

Final Thoughts: Which Route Is Right for You?
There’s no one-size-fits-all when it comes to Interrail. That’s the beauty of it. You get to shape your own rhythm, follow your curiosity, and adapt as you go. Still not sure where to begin?
- Pick Route 1 (Classic Western Europe) if you want iconic cities and a safe first-time experience.
- Choose Route 2 (Southern Sun) if you’re chasing beaches, good food, and a slower pace.
- Go for Route 3 (Eastern Europe Loop) if you love discovering lesser-known places and stretching your budget.
- Try Route 4 (Northern Nature + Nordics) if you want peace, nature, and cooler climates.
Whichever you pick, remember: it’s not about ticking off boxes. It’s about slow mornings, unexpected detours, and unforgettable moments. That’s what makes Interrailing one of the best ways to experience Europe.
Happy travels!
