From June 1 to August 31, 2022, visitors can use all public local and regional transport for nine euros per month. The so-called 9-euro ticket is valid for any number of journeys in the selected month on regional trains, S-Bahn and U-Bahn trains, buses and trams. 

By linking the various transport associations, it is possible to explore the whole of Germany with local transport. €9 tickets are not valid on long-distance trains (e.g. IC or ICE) or long-distance buses. 

Tickets can now be purchased throughout Germany from ticket machines, in train stations or online via the sales channels of Deutsche Bahn or local transport associations. Children under the age of 6 ride for free. Like all users of the 9-euro ticket, children from the age of 6 pay 9 euros per calendar month. There is no extra child ticket with this special offer. The conditions of the respective transport association apply to the transport of bicycles.
