How to buy tickets:

The most affordable way of buying tickets for public transport is to use the “9 Euro Ticket”. This will give you free public transport within Cologne and Germany for the whole of June. It should be available to buy from any Deutsche Bahn or KVB (Cologne public transport) ticket machine. See here for more details:


Please note that this ticket covers only local trains (S-bahn, tram, U-Bahn/subway) but not IC, ICE and EC long distance trains.
