Travelling across Europe by train is one of the most enjoyable ways to see the continent. Instead of spending your journey inside an airport or rushing from one terminal to another, you can watch cities, forests, rivers and countryside pass outside your window.
And despite rising travel costs, budget rail travel in Europe is still possible in 2026 — but there is an important distinction to make.
You may be able to find a few long-distance train journeys for under €100 in total if you book early and choose the right routes. That does not mean a five-day European holiday will cost under €100. Accommodation, food, local transport and sightseeing are separate expenses.
A good example is the popular Central European route:
Berlin → Prague → Vienna → Budapest
It crosses four countries: Germany, Czechia, Austria and Hungary, while connecting four major cities with relatively straightforward rail journeys.
This guide explains where the savings are genuine, where the original “under €100” idea needs qualification, and how to build a more realistic 2026 rail budget.

Why Choose Train Travel in Europe?
Europe has an extensive international railway network, with high-speed, intercity, regional and overnight services connecting major cities.
For travellers, trains offer several practical advantages.
Comfort
You generally avoid the airport-style process of security screening and boarding. On many routes you can also walk around, use a table or work from your seat.
City-centre travel
Major railway stations are often much closer to the city centre than airports. This can save both time and the cost of getting into town.
Scenic journeys
A train journey is part of the trip rather than simply transportation between two airports. Central Europe is particularly rewarding for this because several routes pass through riverside and rural landscapes.
A lower-emission option
The environmental advantage should not be exaggerated as a universal fixed percentage because emissions depend on the train, electricity mix, occupancy and the alternative being compared.
However, the European Environment Agency identifies rail as the lowest-emission major transport mode in the EU in terms of overall transport-sector greenhouse-gas emissions, and describes rail as highly energy efficient with low greenhouse-gas and air-pollution emissions.
Editorial analysis: If a convenient train replaces a short-haul flight, the environmental case for choosing rail is strong. But the cheapest ticket is not necessarily the most environmentally important factor; the route, train and alternative transport mode matter too.
Can You Really Travel Across Europe by Train for Under €100?
Yes — for selected rail journeys, not for the whole holiday.
The original example of Berlin → Prague → Vienna → Budapest remains a useful budget route, but the individual prices should be treated as advance-fare examples rather than guaranteed prices.
Current official railway information gives us a useful illustration:
- Berlin → Prague: Deutsche Bahn currently advertises fares from about €19.98 on some services, with other departures on the same route showing higher starting prices. A current timetable example also shows direct journeys taking roughly 4 hours.
- Prague → Vienna: České dráhy lists First Minute Europe fares from €18.50 in second class when the limited advance allocation is available.
- Budapest → Vienna: MÁV lists START Europa fares from €13 in second class for limited, train-specific tickets.
Using those advertised starting fares as a simple illustration:
€19.98 + €18.50 + €13 = €51.48
So the three intercity legs can theoretically come to about €51.50 when the lowest advertised advance fares are available.
That is considerably below €100.
But there is an important catch
These are “from” prices, not a promise that you will find all three tickets at those prices for your dates.
Railway operators use limited advance-fare allocations and demand-based pricing. Once the cheapest allocation sells out, the next available fare can be considerably higher.
So a better headline for 2026 is:
A four-country European train itinerary can sometimes cost under €100 in intercity rail tickets — if you book early and have flexible dates.
That is more useful and more accurate than suggesting the entire five-day trip costs under €100.
The Berlin → Prague → Vienna → Budapest Route
This route works well for a first Central European rail trip because the cities are geographically logical rather than requiring large backtracking.
1. Berlin → Prague
Berlin is the natural starting point if you want to begin in Germany.
Deutsche Bahn's current route information shows direct Berlin–Prague services, with some advertised fares from €19.98 and journey times of roughly four hours on the examples currently displayed. Other departures can cost more.
Best for: travellers arriving in Berlin who want a relatively simple international train journey.
Think twice if: you are starting your holiday somewhere far from Berlin. Flying into another European city and then travelling back to Berlin simply to follow this itinerary could erase the convenience and savings.
Editorial analysis: This is one of the strongest legs of the itinerary because you get an international journey without spending most of the day on a train.
2. Prague → Vienna
Prague and Vienna make a natural pairing.
České dráhy's First Minute Europe offer lists Prague–Vienna second-class tickets from €18.50, subject to availability. The cheapest fares are limited and should be booked in advance.
The same official source says international First Minute Europe tickets can be purchased up to 180 days before departure, with sales ending when the allocated contingent sells out or close to departure depending on the ticket class.
Best for: travellers who want to combine two historic capitals without changing the overall direction of the trip.
Think twice if: your priority is the absolute lowest possible transport cost rather than visiting both cities. A slightly different route may occasionally produce a cheaper combination.
Editorial analysis: Prague is generally the easier city in this itinerary for travellers trying to keep daily spending under control, while Vienna offers a more expensive accommodation and dining environment. That makes Prague particularly useful as the longer stop if your budget is tight.
3. Vienna → Budapest
The final rail leg takes you from Austria into Hungary.
MÁV currently lists START Europa fares from €13 for Budapest–Vienna in second class, although these are limited train-specific fares rather than a guaranteed walk-up price.
MÁV also publishes international timetables and warns that schedules can change because of construction or other operational reasons, so travellers should check the live timetable before departure.
Best for: travellers finishing their trip in a relatively affordable Central European capital.
Think twice if: you have a flight from Vienna. Budapest is a better final destination if you actually want to spend time there; otherwise, adding another city may create unnecessary transport and accommodation costs.
Editorial analysis: This is the route's strongest budget feature. Budapest can offer a lower-cost final stop than Vienna, particularly for travellers willing to use public transport and choose inexpensive accommodation.
A More Realistic 5-Day Itinerary
The original itinerary is useful, but the budget needs to be presented more honestly.
Five days is enough to experience these four cities, but it is fast-paced. You will spend a meaningful portion of the trip travelling between destinations.
If you prefer slower travel, consider removing one city and spending an extra night in the others.
Day 1 — Berlin to Prague
Take an early direct train from Berlin to Prague.
Current DB examples show direct services of roughly four hours, although journey times vary by departure.
After checking in, spend the afternoon and evening around Prague's historic centre.
Good low-cost choices include:
- Walking through the Old Town
- Charles Bridge
- Exploring the streets around Prague Castle
- Watching the city from one of its public viewpoints
- Walking along the Vltava
Budget strategy: walking is your friend in central Prague. Don't automatically buy a tourist transport pass if most of your sightseeing is concentrated in the centre.
Day 2 — Explore Prague
Give Prague a full day.
One useful 2026 price to know is Prague's public-transport tariff. From January 2026, an adult 30-minute ticket costs 36 CZK through the PID Lítačka app or 39 CZK on paper, while a 90-minute ticket costs 46 CZK electronically or 50 CZK on paper. A 24-hour ticket costs 140 CZK electronically or 150 CZK on paper.
This makes public transport relatively easy to budget.
What about Prague Castle?
Prague Castle's official visitor information currently lists the basic circuit at 450 CZK for an adult, with a reduced price of 300 CZK and family ticket of 950 CZK. The ticket is valid for two days, although individual buildings can generally be entered once.
That matters because “Prague is cheap” does not mean every attraction is cheap.
Editorial analysis: If you're travelling on a strict budget, you don't need to pay for every major attraction. Pick one or two paid sights and fill the rest of the day with walks, neighbourhoods, viewpoints and public spaces.
Day 3 — Prague to Vienna
Take a morning train to Vienna.
An advance Prague–Vienna ticket can start from €18.50 under the ČD First Minute Europe offer when the relevant allocation is available.
Once in Vienna, spend the afternoon exploring on foot.
Possible low-cost activities include:
- Walking around the historic centre
- St. Stephen's Cathedral
- The Ringstrasse
- Public parks
- The Danube and canal areas
- Exploring different neighbourhoods rather than filling the day with paid attractions
Vienna is where your budget may start to feel tighter.
Wiener Linien's 2026 fares show a 24-hour digital Vienna ticket at €9.70 and a 7-day digital ticket at €25.20. A digital single journey is €3.00.
The old 48- and 72-hour Vienna tickets are no longer sold under the 2026 tariff structure; for longer stays, the seven-day ticket can be worth considering.
Budget tip: Don't buy a seven-day ticket automatically just because it is good value per day. For a short stay, compare it with the number of journeys you actually expect to make.
Day 4 — Vienna to Budapest
Travel from Vienna to Budapest.
MÁV's current START Europa offer lists Budapest–Vienna fares from €13, subject to the limited advance allocation.
After arrival, explore Budapest's central areas and the Danube waterfront.
Budapest's public-transport prices are also worth checking before your trip. BKK currently lists:
- Single ticket: 500 HUF
- Single ticket purchased on the spot: 700 HUF
- 30-minute ticket: 600 HUF
- 90-minute ticket: 850 HUF
- 24-hour travelcard: 2,750 HUF
- 72-hour travelcard: 5,750 HUF
These are official BKK fares, but the correct ticket depends on how often you travel.
Editorial analysis: For a traveller staying mostly around central Budapest, paying for individual journeys may be better than buying a pass. If you expect several journeys every day, the 24- or 72-hour option becomes easier to justify.
Day 5 — Explore Budapest
Use your final day for a slower exploration of Budapest.
Consider:
- Walking along the Danube
- Buda Castle district
- Fisherman's Bastion area
- Central Market Hall
- Public squares and neighbourhoods
- Thermal baths if they fit your budget
The key lesson is that Budapest can be inexpensive, but you can still spend heavily if you stack paid attractions, restaurants, nightlife and tours into the same day.
What Does the Whole Trip Actually Cost?
This is where a transparent budget is more useful than simply saying “Europe under €100.”
The €51.48 figure above is only an illustrative combination of three advertised starting fares. It excludes accommodation, food, city transport, attractions and any other travel costs.
For comparison, Budget Your Trip's 2026 traveler-spending data puts the average budget-traveller daily spend at roughly:
- Prague: about US$60 per day
- Vienna: about €68 per day
- Budapest: about US$49 per day
These are third-party benchmarks based on reported traveller spending, not official government prices, and individual trips can be much cheaper or more expensive.
For example, simply using the published budget-traveller benchmarks for one day in each city already illustrates why a €100 total holiday budget is unrealistic.
A better way to think about the €100 target

|

That distinction makes the advice much more useful for someone actually planning the trip.
Should You Book Individual Tickets or Use a Rail Pass?
This is one of the most important decisions for budget travellers.
Individual tickets
For a fixed itinerary such as Berlin → Prague → Vienna → Budapest, individual advance tickets are often the first thing I would compare.
Why?
Because you already know your route, and the cheapest advance fares can be surprisingly low.
Best for:
- Fixed itineraries
- Travellers willing to book early
- People making only a few long-distance journeys
- Budget travellers who don't need maximum flexibility
Think twice if:
- Your plans may change
- You want to add several destinations
- You dislike train-specific tickets
- The cheapest fares have already sold out

What About Interrail?
Interrail can be excellent, but it is not automatically the cheapest option.
The current Interrail system covers 33 European countries. However, many high-speed and night trains require reservations that are not included in the pass price. Public transport such as ordinary city buses and trams is also generally outside the pass.
That means you should compare:
Interrail pass + reservations
against
individual advance tickets
rather than comparing the pass price with one train ticket.
Interrail itself notes that slower services can sometimes avoid reservation costs, although this may mean longer journeys or additional changes.
Editorial analysis: For the four-city itinerary in this article, I would not buy a rail pass simply because the journey crosses multiple countries. Three relatively straightforward intercity legs are exactly the kind of trip where individual advance fares can be competitive.
A pass becomes more interesting when you start adding several additional journeys and value flexibility more highly than the absolute lowest price.
Overnight Trains: Are They Actually Cheaper?
Overnight trains can be useful, but the old idea that they automatically save money needs a little more thought.
ÖBB Nightjet fares depend on availability and demand. ÖBB says its cheapest Sparschiene fares are limited and recommends booking early. Nightjet tickets can generally be purchased up to 180 days before departure, although timetable-change periods can have shorter booking windows.
The important calculation is:
Night-train price + accommodation saved + time saved
not simply:
Night-train price = cheap
A seat may be relatively inexpensive but uncomfortable for sleeping. A couchette or sleeper costs more but can provide a genuine overnight accommodation alternative.
Best for:
- Long journeys
- Travellers who value saving daytime travel hours
- People who would otherwise pay for a hotel that night
Think twice if:
- You sleep badly on trains
- The journey is short enough to make daytime rail easier
- A sleeper costs more than the accommodation you would otherwise book
Booking Strategies That Actually Save Money
1. Book when the cheap fare is available
European railway tickets are not all sold under one pricing system. Some have limited advance allocations, while others behave differently.
For example, ČD's First Minute Europe tickets have limited allocations, and MÁV's START Europa fares are also available in limited numbers.
Don't assume that waiting until the week before travel will produce the cheapest fare.
2. Compare the railway operator with third-party booking sites
Platforms such as Omio and Trainline can make international journeys easier to compare, but they may not always be the cheapest place to purchase.
For important journeys, check the relevant national railway operator as well.
Useful official starting points include:
Editorial analysis: A third-party platform can be worth using for convenience, especially when comparing several operators. But convenience and lowest price are not necessarily the same thing.
3. Don't automatically choose the fastest train
If you have plenty of time, a slower service can sometimes reduce the price and may avoid certain reservation charges.
Interrail specifically notes that choosing trains without reservation requirements can sometimes reduce costs, although the trade-off is longer journey times or more changes.
4. Compare the complete journey, not just the ticket
A €5 cheaper train is not necessarily the better deal if it arrives at a station requiring an expensive transfer or arrives several hours later.
Consider:
ticket + station transfer + local transport + time
rather than the train fare alone.
Travel During Shoulder Season — But Don't Promise Huge Savings
Spring and autumn can be excellent times to travel around Central Europe.
However, the original claim that train and hostel prices can simply “double” in summer is too broad to present as a fact.
Prices vary by:
- city
- accommodation
- event calendar
- school holidays
- train operator
- booking date
- demand
- exact travel date
So instead of assuming a fixed percentage saving, compare your actual dates.
My editorial preference: May, early June, September and October can be attractive compromises between weather, daylight, crowds and prices, but the best month depends heavily on your priorities.
City-by-City Budget Reality
Prague
Advantages
- Compact historic core
- Excellent public transport
- Many sightseeing opportunities that cost nothing
- Official 2026 public transport fares remain relatively manageable
Limitations
- Major attractions can add up quickly
- Popular central areas can be expensive
- Prague Castle's standard circuit is now 450 CZK
Best for: travellers who want history and atmosphere without relying on expensive attractions every day.
Think twice if: you expect every famous sight to be inexpensive.
Vienna
Advantages
- Excellent public transport
- Very walkable historic centre
- Strong museums, architecture and public spaces
- Convenient connections to neighbouring countries

- Major attractions can quickly turn a low-cost day into an expensive one
- 2026 public transport fares have changed, including the removal of the former 48- and 72-hour tickets
Best for: travellers who want architecture, museums and classical European city life.
Think twice if: your entire holiday budget is extremely tight.
Budapest
Advantages
- Strong public transport network
- Many atmospheric walks and viewpoints
- Wide range of food and accommodation choices
- Official 2026 public transport fares provide several flexible options
Limitations
- Thermal baths, nightlife and paid attractions can quickly increase spending
- Currency is the Hungarian forint rather than the euro
- Tourist-focused areas may cost substantially more than neighbourhood alternatives
Best for: travellers wanting a relatively flexible Central European city with plenty of low-cost sightseeing.
Think twice if: you're travelling mainly for nightlife and paid experiences on a strict budget.
The €100 Rail Challenge: A Better 2026 Version
If your goal is specifically to keep long-distance rail fares below €100, this is how I would approach the trip.
Step 1
Choose your dates before booking.
Step 2
Check Berlin → Prague first.
Step 3
Check Prague → Vienna.
Step 4
Check Vienna → Budapest.
Step 5
Add the three fares together.
For example, using the currently advertised starting fares cited above:
€19.98 + €18.50 + €13 = €51.48
That leaves a theoretical €48.52 before reaching €100.
But don't treat the €51.48 result as a guaranteed price. The fares are availability-dependent, and they may not be available on your dates.
My practical target
I would personally use:
- Under €70: excellent rail deal
- €70–€100: still a strong budget result
- €100–€150: reasonable if your dates are fixed
- Over €150: compare alternative dates, operators and routes
These thresholds are my editorial framework, not official industry categories.
Bonus Tips for Keeping the Trip Affordable
Bring simple food for the train
A supermarket sandwich or packed meal can cost considerably less than buying everything at stations.
Carry a refillable bottle
It is useful throughout the trip, although you should check local drinking-water guidance where relevant.
Use local public transport strategically
Don't buy a city pass just because it is marketed to tourists. Calculate how many journeys you are actually likely to make.
Download offline information
Save your accommodation address, railway tickets, maps and important booking details before leaving Wi-Fi.
Leave a financial buffer
This is one of the most important budget tips.
If your calculated transport budget is €95, don't build a trip around the assumption that every fare will remain exactly €95.
Leave room for:
- fare increases
- sold-out cheap tickets
- luggage fees where applicable
- station transfers
- unexpected changes
- food during long journeys

My recommendation
For Berlin → Prague → Vienna → Budapest, I would start by pricing the three journeys individually.
The route is short enough that you don't need a rail pass simply because you are crossing national borders. If the advance fares are available, individual tickets can make the budget much easier to control.
If you plan to expand the trip to six, seven or more rail journeys, then compare an Interrail pass against the individual fares.
And if your priority is the overall holiday budget, don't spend all your planning energy chasing a €10 saving on a train ticket. Accommodation can have a much larger effect on the final cost.
Final Thoughts
Travelling through Europe by train for under €100 is still possible in 2026 — if we define the €100 target correctly.
For the Berlin → Prague → Vienna → Budapest itinerary, current official railway information shows that very low advance fares can bring the three main intercity journeys to roughly €51.48 at the advertised starting prices used in this guide.
But that is a rail-fare calculation, not a five-day holiday budget.
Once accommodation, food, local transport and attractions are included, the real cost is much higher. That is not a failure of budget travel — it simply gives you a more honest number to plan around.
The bigger advantage of this route is that the four cities fit together naturally. You can start in Germany, continue through Czechia and Austria, and finish in Hungary without unnecessary backtracking.
For a budget traveller, the winning strategy is therefore simple:
book the long-distance trains early, compare official railway fares, avoid paying for attractions you don't really want, use city transport intelligently, and keep a buffer for price changes.
The goal isn't to make Europe artificially cheap.
It's to spend your money where it actually improves the trip.

Price Variability and Exclusions
All prices in this article should be checked again before booking.
Rail fares can change according to:
- travel date
- departure time
- availability
- booking time
- ticket type
- class
- operator
- special events or timetable changes
“From” fares are particularly important to interpret correctly: they represent an available starting price, not a guaranteed price for every journey.
The budgets in this article exclude international flights to Europe, visas, travel insurance, accommodation unless specifically stated, meals, attractions, airport transfers, optional seat reservations, luggage-related charges where applicable, shopping and personal expenses.
Currency conversions are intentionally avoided where possible because exchange rates change continuously.
Editorial analysis and recommendations are clearly identified as such; sourced prices, transport rules and spending benchmarks are presented separately from personal judgement.
