  • Getting from Vienna International Airport to the City Centre

    Vienna airport is well-connected to the city by public transport.

    • S-Bahn/Regionalbahn (S7, R7, direction Wolkersdorf) and ÖBB trains: The most budget-friendly option. The S7/R7 train takes around 25 minutes to the station Wien Mitte and runs every 20-30 min. ÖBB trains (mostly railjet) connect to Vienna’s main train station (Hauptbahnhof). Buy a ticket at one of the ÖBB ticket machines at the airport train station, or from the ÖBB ticket counter in the airport. Note that if you already own a Vienna city ticket for public transport, you only need to buy a ticket from Vienna airport to “Schwechat” (this is the city boundary). Don’t forget to get this extra ticket, else it can result in a fine.
    • City Airport Train (CAT): This express train runs every 30 minutes, taking you directly to Wien Mitte station in 16 minutes.
    • Buses: Vienna Airport Lines operate buses that connect the airport with key locations in the city, such as Schwedenplatz and Westbahnhof.

  • Good to know

    • Vienna is one of the safest cities in Europe, with low crime rates. However, as in any major city, be mindful of your belongings, especially in crowded areas like public transport or tourist attractions.
    • Vienna is and has always been a very international city and most people speak English. When using public escalators, stand on the right side to allow others to pass on the left (people take this seriously).
    • In restaurants/cafés/for taxi fares, rounding up the bill (e.g., adding 5-10% tip) is common. Simply state the total amount you’d like to pay when handing over money.
    • Austrians are known for their love of coffee houses as an oasis of ‘Gemütlichkeit’ and their many types of coffee.
    • Vienna’s tap water comes from alpine springs and is of excellent quality. Feel safe to drink it directly from the tap.
    • Most places accept credit and debit cards, but it’s a good idea to carry some cash for smaller establishments or markets.
    • Emergency numbers: Dial 133 for the police, 144 for medical emergencies, and 122 for the fire department.
