Once landed on Vienna airport, it’s very easy to travel to the city centre. You just take the train! The trainstation is perfectly located underneath the airport.
Now, you have two options. You can travel with the green City Airport Train (CAT or City Express) that takes you to the centre in 16 minutes. You can buy the tickets at the green ticketmachines.
But if you want to save some money and are not in a real hurry, you can also take the normal train/S-Bahn (ÖBB), that takes you to the heart of the centre in 30 minutes and costs only € 4,40. You buy the tickets at the red ticketmachines, on the trainplatform. Both trains are very comfortable and clean. More info >
