Vienna has one of the finest public transport networks in Europe. The Wiener Linien system combines five U-Bahn (metro) lines with an extensive tram network, city buses and night buses into a seamless, punctual whole. A single ticket covers all modes, and the fares are low enough that most visitors will barely think about the cost — getting around Vienna is simply not an obstacle.
The U-Bahn: the backbone of the city
Vienna's U-Bahn has five lines — U1 (red), U2 (purple), U3 (orange), U4 (green) and U6 (brown) — covering the city in an interlocking grid. There is no U5 yet, though one is under construction. The lines do not all meet at a single central hub; instead they intersect at various interchanges, which gives the network flexibility but requires slightly more planning than a simple hub-and-spoke system.
Key stops and intersections:
- Karlsplatz: U1, U2 and U4 all meet here, making it the most connected interchange in the system. Close to the Staatsoper (State Opera), the Musikverein and the Naschmarkt.
- Schottenring: U2 and U4, at the northern tip of the Ringstraße, near the Votivkirche and the Danube Canal.
- Schwedenplatz: U1 and U4, at the heart of the old Jewish quarter, near the Donaukanal and easy walking distance to the Bermuda Triangle bar district.
- Stephansplatz: U1 and U3, directly beneath the Stephansdom cathedral — the single most useful stop in Vienna for orientation.
- Westbahnhof: U3 and U6, at Vienna's western mainline station for trains to Salzburg, Germany and beyond.
- Wien Hauptbahnhof: U1, at the main rail hub for long-distance ÖBB trains, including the popular Nightjet sleeper services.
The U-Bahn runs from around 05:00 to around 00:30 on weekdays. On Friday and Saturday nights it runs 24 hours — a genuinely useful feature in a city with Vienna's café, bar and opera culture.
Trams: slow but charming (and practical)
Vienna's tram network is extensive and covers streets the U-Bahn does not reach, particularly along the Ringstraße itself. The famous Ring Tram loop is partly a tourist experience, but the working trams — particularly the D, 1, 2, 71 and others — are a practical way to move around the inner districts. Trams run frequently during the day and are especially useful for journeys along the Ringstraße between the museums, opera house and parliament.
The same ticket covers U-Bahn and trams: tap in once when you board (or validate a paper ticket) and you can transfer between modes freely within the validity window.
Tickets and passes
Wiener Linien uses a relatively simple ticketing structure. For visitors, the most useful options are:
- Single trip (Einzelfahrt): Valid for one uninterrupted journey in one direction — you can change between U-Bahn, tram and bus without buying another ticket. Pricier per journey than any multi-ride option.
- 24-hour ticket (24-Stunden-Karte): Unlimited travel for 24 hours from first validation. Very reasonable price for a day of sightseeing.
- 48-hour and 72-hour tickets: Proportionally good value; the 72-hour option is ideal for a three-night city break.
- 8-day climate ticket (8-Tage-Karte): Eight days' unlimited travel that do not need to be consecutive — simply validate on the days you use it. Can be shared between travellers (validate once per person per day). Surprisingly good value for groups or longer visits.
- Vienna City Card: Combines unlimited travel with discounts at museums, sights and restaurants. Worth comparing against the raw transport card depending on your museum plans.
Tickets are bought from the orange vending machines in U-Bahn stations, at some tram stops, or on the Wiener Linien app. The machines have an English option. Validate paper tickets before boarding — there are orange validation machines at station entrances and on trams. Travelling without a valid ticket or without validation carries a significant on-the-spot fine, and inspectors operate in plain clothes.
Don't forget to validate: Vienna's system is honour-based — there are no turnstiles on trams or at some U-Bahn stations. Ticket inspectors do check regularly and the fine for travelling without a valid, validated ticket is substantial.
Night transport
On Friday and Saturday nights, all five U-Bahn lines run continuously through the night. On other nights, the U-Bahn closes around 00:30 and Nightline buses (N-routes) take over, covering similar corridors to the U-Bahn lines throughout the night. The night buses run until the U-Bahn resumes in the early morning. Standard tickets and passes are valid on night buses.
Getting to the airport
Vienna Airport is not served by the standard Wiener Linien network. To reach Vienna Airport, you take either the City Airport Train (CAT) or the S7 S-Bahn, both departing from Wien Mitte/Landstraße station on the U3 and U4 lines. Standard Wiener Linien tickets are valid on the S7 within city zones but require an airport-zone supplement for the journey to Schwechat.
Practical tips for getting around Vienna
- Vienna's historic centre (the First District) is compact and walkable. Many top sights — the Stephansdom, the Hofburg, the Kunsthistorisches Museum, the Belvedere — are all within 20–30 minutes of each other on foot. Combine walking with the occasional tram or U-Bahn rather than always going underground.
- The Ringstraße is genuinely beautiful and walking or cycling its full circuit (about 5.5 km) is one of the best free things to do in Vienna.
- Schönbrunn Palace is reached via U4 (Schönbrunn or Hietzing stops). Belvedere is a short walk from the U1's Südtiroler Platz stop.
- The Vienna Card and Wiener Linien app both include a live map of departures, which is useful for checking the next tram when you are on street level.
Vienna is also a superb rail hub for exploring Austria and central Europe. Our guide to travelling Austria by train covers the main routes, including scenic journeys through the Salzkammergut and Tyrol, and the ÖBB Nightjet sleeper network for overnight journeys to Germany, Italy and beyond.
Frequently asked questions
Does the Vienna U-Bahn run all night?
On Friday and Saturday nights (into Saturday and Sunday mornings), all five U-Bahn lines run 24 hours. On other nights the system closes around 00:30 and Nightline buses cover the main corridors until the morning.
What is the cheapest way to get around Vienna for several days?
The 72-hour ticket is good value for a three-day stay with multiple daily journeys. For four or more days, the 8-Tage-Karte (8-day card) works out cheaply per day and has the advantage of being usable on non-consecutive days.
Which U-Bahn line goes to Stephansdom?
Stephansplatz station, directly under the cathedral, is served by U1 (red) and U3 (orange). It is the most convenient starting point for the First District and the pedestrian zones of central Vienna.
Is the Vienna U-Bahn reliable?
Yes — Wiener Linien has a reputation for punctuality and cleanliness. Disruptions are rare and are flagged promptly in the app and at station displays. The network is well-maintained.
