Graz is Austria's second city, the capital of Styria, and one of the most enjoyable cities in Central Europe — yet it sits only about 200 kilometres south of Vienna, well under three hours by train. Whether you are making a day trip or stopping on the way to Slovenia and the Adriatic, the journey is easy and the destination rewards the effort.
The best option: ÖBB railjet and InterCity trains
ÖBB (Austrian Federal Railways) operates regular services between Wien Hauptbahnhof (Vienna Central Station) and Graz Hauptbahnhof throughout the day. The fastest services use the ÖBB railjet, a modern, comfortable high-speed train — typically completing the journey in around 2 hours 35 minutes to 2 hours 45 minutes. Standard InterCity (IC) trains on the route take a little longer, usually around 2 hours 45 minutes to 3 hours, with more stops.
Trains run roughly every hour or better throughout the day on this corridor, which is one of ÖBB's busiest domestic routes. Both Wien Hauptbahnhof (Vienna's main station, opened in 2015 and served by U1 metro) and Graz Hauptbahnhof are modern, central and easy to navigate. Graz station is a 10-minute walk or a short tram ride from the old town.
Seat reservations are not compulsory on most ÖBB domestic trains, including the railjet on this route — you can buy a ticket and board without a specific reservation, though a reservation is recommended on busy weekends or around public holidays. Tickets are available through the ÖBB app, website, or at station machines and counters; advance tickets can be cheaper than full-fare walk-up prices.
Interrail and Eurail pass holders can travel freely on ÖBB trains between Vienna and Graz without a reservation supplement. See our guide to travelling Austria by train for more on passes, tickets and the ÖBB network.
Worth knowing: The railjet on this route runs via the Semmering Pass — a UNESCO World Heritage Site and one of Europe's oldest mountain railway crossings, built in the 1840s. The section through the Semmering is brief but genuinely scenic, with forested ridges and dramatic stone viaducts.
The bus option
FlixBus operates coach services between Vienna and Graz, with several departures per day from Wien Erdberg coach station (reachable from the U3 metro). Journey times are around 2 hours 30 minutes to 3 hours on the fastest services, which is competitive with the train in travel time but less comfortable. Fares can be very low if booked ahead.
The bus mainly appeals if you find a significantly cheaper fare than the train on a given day, or if you are arriving at Vienna's international bus terminal and want to continue directly. For most travellers, the train is preferable for this length of journey.
Driving
The drive from Vienna to Graz on the A2 Südautobahn covers roughly 200 km and takes about 1 hour 50 minutes to 2 hours 15 minutes in normal traffic. The A2 is a toll motorway — you need a valid Austrian vignette (annual sticker, or a short-term digital vignette for 10 days, available at petrol stations and border crossings and now also purchasable online in advance).
Driving saves some time over the train, but Graz city centre parking is limited and paid. A car makes good sense if you plan to explore Styrian wine country (the Südsteiermark, or South Styrian wine road), the Lipica stud farm across the Slovenian border, or the remarkable Riegersburg Castle in the volcanic hills east of Graz — all of which are difficult or impossible by public transport.
Flying
There are no scheduled flights between Vienna and Graz. Graz Airport (GRZ) handles international routes; for domestic travel from Vienna, the train is the standard and sensible option.
Exploring Graz
Graz's old town is a UNESCO World Heritage Site — one of the best-preserved Baroque city centres in Central Europe, with a distinct Italian influence from its long history as a Habsburg city facing south towards the Adriatic. The Schlossberg clock tower looms over the town and can be reached by a lift cut through the rock; the views from the top are excellent. The Kunsthaus Graz ("Friendly Alien") is a striking contemporary art museum that sits in deliberate contrast to the historic surroundings.
Graz is also Austria's food capital by several reckonings — the Styrian cuisine (pumpkin seed oil on everything, Steirisches Backhendl, excellent local wines) and the covered market at the Lendplatz make eating here a genuine highlight.
Which should you choose?
The ÖBB train is the right choice for almost everyone: comfortable, regular, reservation-free and central. The railjet is the most comfortable option when available; regular IC trains are also fine. Take the bus only if the fare is significantly lower and you do not mind the extra travel time. Drive if you plan to explore Styria beyond Graz itself — the wine roads and rural castles are well worth it but require a car.
Frequently asked questions
How long does the train from Vienna to Graz take?
ÖBB railjet services typically take about 2 hours 35 minutes to 2 hours 45 minutes. Standard IC trains are a few minutes slower. Services run roughly every hour throughout the day.
Do I need to book a seat in advance?
Seat reservations are not compulsory on most ÖBB domestic services. You can buy a walk-up ticket and board without a reserved seat. That said, a reservation is worth making on busy travel days to guarantee a specific seat.
Is the Semmering railway included on the Vienna–Graz route?
Yes. All trains between Vienna and Graz cross the Semmering mountain pass, which is a UNESCO World Heritage Site. The section through the Semmering is short but includes viaducts and tunnels through dramatic forested terrain.
Can I visit Graz as a day trip from Vienna?
Yes, easily. A morning departure gives you a full afternoon in Graz before returning on an evening train. Aim for at least five to six hours in the city to see the old town, climb the Schlossberg and visit the market.
