An integrated network of metro, buses, local trains (S-tog) and harbour buses: a 2-zone single ticket, which covers the centre, costs 24 DKK, about €3.20, and is valid for 75 minutes with transfers, 22 DKK with the Rejsekort card; the airport needs 3 zones, 30 DKK; the 24-hour City Pass Small costs 100 DKK; fares since 18 January 2026; for tourists the Copenhagen Card (free entry to over 70 attractions + unlimited transport) or the City Pass for the urban zones only are handy.
- Always remember to 'tap out' with the Rejsekort, otherwise the maximum fare from the starting zone is charged.
- On-board checks are frequent: travelling without a valid ticket means a 750 DKK fine.
- On a bike, always signal with your hand before stopping or turning and use the mandatory white/red lights after dark, on pain of steep fines.
- The harbour buses (buses on the water) are part of the normal public-transport fares, many tourists don't know this and needlessly avoid them.
