Prague and Vienna are two of Europe's most beautiful capital cities, and they sit barely 300 km apart across what was once the heart of the Habsburg Empire. You can do the journey comfortably in a day by several means, with direct trains being the most popular choice. Here is how each option stacks up.

The quickest way: direct trains

Several direct trains make the journey from Prague hlavní nádraží (Prague main station) to Wien Hauptbahnhof each day. The fastest services take around 3 hours 50 minutes to 4 hours 20 minutes, operated by a combination of Czech Railways (ČD) and ÖBB, including Railjet services on part of the route. The journey passes through southern Bohemia and Austria, and the trains are comfortable — a good option for a relaxed half-day of watching the landscape roll by.

Unlike the very fastest cross-border high-speed trains elsewhere in Europe, reservations are generally not compulsory on all services here, though they are advisable in peak season and on busier departures. Booking ahead — through the ČD or ÖBB websites — will also get you better fares than buying on the day.

The cheapest way: long-distance bus

Flixbus and other coach operators run frequently between Prague and Vienna, typically taking around 4–5 hours. Fares at the budget end of the scale can be strikingly low, especially well in advance, and buses depart from Prague's Florenc bus station and arrive close to Wien Hauptbahnhof. For travellers whose priority is cost over comfort, the bus is hard to beat on this route — and the time difference versus the train is not enormous.

The fastest door-to-door (sometimes): flying

Flights do exist between Prague and Vienna, but this is one of the routes where flying makes the least sense. The actual flight time is under an hour, but Prague Václav Havel Airport and Vienna Schwechat are both well away from their city centres, and the transfers, check-in and baggage add up fast. Total door-to-door time for a flight on this route frequently matches or exceeds the train. Fly only if you find an unusually cheap fare, are starting near an airport, or have a long connection to manage.

Driving

The road distance is around 300–330 km and typical driving time is 3–3.5 hours by motorway, passing through southern Bohemia and the Austrian border near Mikulov or Gmünd. Both the Czech Republic and Austria require motorway vignettes — make sure you have the correct sticker or digital registration before joining the motorway network. The drive through the South Bohemian countryside is genuinely pleasant, and Český Krumlov — one of the most beautiful small towns in Central Europe — sits almost exactly halfway, making it an obvious stop if you have time.

The scenic detour via Salzburg

If you are in no hurry, consider going the long way: Prague to Salzburg by train or bus, spending a night there, then continuing south to Vienna. It adds distance and time but gives you one of Europe's most attractive cities as a bonus. Alternatively, a stop in Linz — Austria's often-overlooked third city, with a fine old town and the Ars Electronica museum — breaks the journey agreeably.

Which should you choose?

The direct train is the right choice for most travellers: comfortable, reasonably priced when booked ahead, and city centre to city centre. Choose the bus if budget is tight and you do not mind the slightly longer journey time. Driving rewards those who want to stop — especially at Český Krumlov — or who need a car in Vienna. Flying rarely justifies itself on a 300-km route.

Prague hlavní nádraží: station orientation

Prague's main station has a distinctive Art Nouveau original hall alongside a more functional modern lower level, where most international departures, including trains to Vienna, are handled. Signage is in Czech and English, and platform numbers are usually confirmed 20–30 minutes ahead on the departure boards. The station sits a short walk or one metro stop (Hlavní nádraží, line C) from Wenceslas Square, so it is easy to reach on foot from most central hotels with light luggage.

Comfort and luggage on board

Railjet and EC trainsets on this route have generous overhead racks and dedicated luggage stacks near the vestibules, comfortable for typical holiday luggage. A dining or bistro car operates on most Railjet services, serving hot food and drinks for the roughly four-hour journey — useful given the trip spans a natural lunch or early-dinner window depending on your departure time. Both first and second class are available; second class on Railjet is well-appointed and perfectly comfortable for this journey.

Practical tips for first-timers

• Carry your passport or ID card even though this is an all-Schengen journey — spot checks near the Czech-Austrian border do occur periodically.
• If travelling with an Interrail or Eurail pass, check whether your specific train requires a reservation before boarding, since this varies by service on this corridor.
• Currency changes at the border — the Czech Republic uses the koruna, not the euro, so have both currencies or a card that handles conversions smoothly if you plan to buy food or drink at either end.

Money-saving tips

Both ČD and ÖBB release cheaper advance fares that climb as the train fills, so booking a few weeks ahead is the most reliable way to save on the train. FlixBus fares follow the same logic even more steeply — the earliest bookings on this route can be a fraction of a late booking, so if the bus is your chosen mode, lock in a date as early as possible.

Accessibility notes

Both Prague hlavní nádraží and Wien Hauptbahnhof have step-free access via lifts, and Railjet trains carry a wheelchair-accessible space in most trainsets — contact ČD or ÖBB assistance services at least 24–48 hours ahead of travel to arrange boarding help, since older rolling stock occasionally still used on this route has a bigger step up from the platform than the newest sets.

Prague also connects well to Berlin by train, and Vienna onwards to Budapest — making this a natural link in any Central European loop. For night-train enthusiasts, ÖBB Nightjet services from Vienna connect to a number of onward destinations.
