While the metro and tram systems are often the easiest and quickest way to get around Vienna during the day, they stop running at around midnight, making buses and taxis the two options for travelling at night time.
If you're planning a night out in Vienna, the night bus could be the best way to travel home. They operate between 12:30 am and 5 am and run every 30 minutes. There are 26 night bus lines, and the route numbers begin with the letter 'N'.
Tickets for travel on night buses are the same price as their daytime public transport equivalents, and you can buy the ticket on the bus - although, like the rest of Vienna's transport tickets, it's cheaper to buy in advance.
