Why Choose Train Travel in Europe?
Europe has one of the world’s most advanced and connected rail systems. From high-speed trains like France’s TGV and Germany’s ICE to scenic regional routes in Austria or Switzerland, the network covers almost every major city and town.
Train travel offers several advantages:
-
Comfort: Spacious seats, no baggage restrictions, and freedom to move around.
-
Flexibility: Many trains let you hop on and off with open tickets or travel passes.
-
Sustainability: It’s eco-friendly — trains produce far less carbon emissions than planes.
-
Scenery: You enjoy stunning views of landscapes, lakes, castles, and villages right outside your window.
But the real charm lies in discovering how to do all this on a tight budget.
How to Keep Your Train Travel Under €100
1. Pick Budget-Friendly Routes
Not all routes are equally expensive. Western European countries like France, Switzerland, or the UK often have higher ticket prices, while Central and Eastern Europe are much cheaper.
For example, this popular and scenic route can easily fit under €100 if you book early:
-
Berlin → Prague: around €20
-
Prague → Vienna: €15–€20
-
Vienna → Budapest: €10–€15
That’s just around €45–€55 for travelling across three countries — Germany, Czech Republic, Austria, and Hungary.
You’ll still have money left for snacks or short local trips!
2. Book in Advance
Train tickets in Europe work a lot like flight tickets — the earlier you book, the cheaper they are.
Use trusted platforms such as:
-
Omio (user-friendly, shows best deals)
-
Trainline (great for cross-country travel)
-
Deutsche Bahn (DB) (Germany-based but covers much of Europe)
If you plan your trip a few weeks ahead, you can easily get discounts of 30–60% compared to last-minute bookings.
3. Travel Overnight
Overnight trains are a hidden gem for budget travelers. You save both time and one night of accommodation.
Trains like ÖBB Nightjet (Austria) or RegioJet (Czech Republic) offer sleeper seats and couchettes at affordable rates. You can sleep comfortably and wake up in another country — that’s both efficient and cheap.
4. Use Train Passes and Regional Deals
Sometimes, individual tickets cost more than a travel pass. Europe offers many regional passes that are ideal for short multi-country trips.
Here are some excellent options under €100:
-
Benelux Pass: Covers Belgium, Netherlands, Luxembourg.
-
Balkan Flexipass: Ideal for exploring Eastern Europe (Serbia, Croatia, Bulgaria, etc.).
-
Interrail One Country Pass: Choose one country (like Italy or Spain) and travel freely for a few days.
These passes give you flexibility and allow spontaneous stops along your route.
5. Travel During Off-Season
Prices for trains (and even hostels) can double in summer (June to August). Traveling in spring (April–May) or autumn (September–October) not only saves money but also gives you fewer crowds, cooler weather, and more local experiences.
