Think of Copenhagen transport as one network

On a first visit, the Metro, buses, S-trains, regional trains and harbour buses can appear to be separate systems. The first thing to understand is that they are connected by a common fare structure. Within the zones and period covered by a valid ticket, you can change from the Metro to a bus, from a train to a harbour bus, or combine several modes without buying a new ticket for each vehicle.

In other words, there is no need to think in terms of a “Metro ticket” and a “bus ticket”. The useful questions are which zones your journey requires and how long the ticket remains valid. Walking and the Metro often work best in the centre; buses fill the gaps between stations; S-trains and regional trains take you out to the suburbs. The strength of the system lies in combining them.

Central Copenhagen has a dense network of stops and stations, and the Metro operates around the clock. Once you recognise the main hubs — Nørreport, København H (Copenhagen Central Station), Kongens Nytorv and Østerport — you do not need to memorise the entire map. Treating the city as one transport system is the simplest way to travel.

Zones — fares are based on distance, not the vehicle

Public transport in Copenhagen and Zealand uses a zone system. The fare is determined by the zones needed between your origin and destination, not by whether you take the Metro, a bus or a train. A Single Ticket starts at two zones; as of September 2026, the lowest adult fare is DKK 24. Within the purchased zones and validity period, the same ticket can be used across the different modes.

Counting zones from a map is not always intuitive. The airport appears in zone 4, but the Metro has a “ring zone” rule: on the M2, a journey is charged at a maximum of three zones. City Pass Small, by contrast, covers zones 1–4. The same airport journey can therefore look different depending on the product you buy. This is one reason it is safer to enter your origin and destination in the official app.

Rejsebillet or a station ticket machine will calculate the required zones when you enter the journey. If you are travelling to the Louisiana Museum of Modern Art, Frederiksborg Castle or Kronborg Castle, do not assume that a city-centre ticket is enough. Search the destination before you travel and check the coverage of your chosen pass.

The Metro — the city’s 24-hour backbone

Copenhagen’s Metro consists of four automated lines — M1, M2, M3 and M4 — and runs 24 hours a day. During the day, trains are frequent enough that you rarely need to plan around a timetable. The official line information gives a useful guide: approximately every two minutes during rush hour and every three minutes during daytime, evening and weekends. Overnight, the interval is about eight minutes on Friday and Saturday nights and about 20 minutes on Sunday to Thursday nights. Planned works can change this, so check the service status when travelling late.

  • M1: Vanløse–Vestamager, passing Frederiksberg, Nørreport, Kongens Nytorv, Christianshavn and Ørestad.
  • M2: Vanløse–Copenhagen Airport. In the central section it shares tracks with M1.
  • M3 Cityringen: a 17-station underground loop around the centre. A full circuit takes about 28 minutes and links Vesterbro, Frederiksberg, Nørrebro and Østerbro.
  • M4: Orientkaj–København Syd, running through the centre and Sydhavnen, with direct stops at København H and Rådhuspladsen.

Frederiksberg and Kongens Nytorv are the main interchange points between M1/M2 and M3/M4. M3 is a circle line, so rather than memorising “clockwise” and “anticlockwise”, check the displayed via-station and arrival time on the platform. Stations are clearly signed in English and generally have lifts as well as stairs. The absence of a gate at some stations does not mean that a ticket is optional.

Buses — connecting the streets beyond the Metro

Buses are most useful for neighbourhoods away from Metro stations and for destinations between rail lines. A-buses and the 5C are frequent central routes, S-buses make fewer stops and are designed for faster cross-city journeys, and N-buses operate at night. Rather than trying to memorise every route type, search the destination in Rejseplanen and follow the suggested service and direction.

Look for the yellow bus symbol at a stop. A bus may pass through if the driver cannot see anyone waiting, and it will not stop for a passenger getting off unless the stop button has been pressed. Stand where the driver can see you, and press the button before your stop.

A practical Copenhagen detail is the cycle lane between the pavement and the road on many streets. Look both ways before stepping into it to board or leave a bus. The comfort of the bus network depends not only on the vehicles but also on the city’s bicycle-first street design.

S-trains and regional trains — reaching destinations beyond the centre

The red S-trains connect central Copenhagen with the metropolitan area. They serve København H, Vesterport, Nørreport and Østerport, then extend towards Frederiksberg, Nørrebro, Hellerup, Klampenborg and Hillerød. For a short journey in the centre, the Metro is often easier; for suburbs, parks and northern destinations, an S-train can be faster.

Regional and InterCity trains connect Copenhagen with the rest of Zealand, Denmark and Sweden. For a design- and architecture-focused itinerary, take a regional train to Humlebæk for the Louisiana Museum of Modern Art, an S-train to Hillerød for Frederiksborg Castle, or a train to Helsingør for Kronborg Castle. The same integrated fare structure may apply, but the number of zones is greater, so confirm the journey before buying.

By 2026, the Greater Copenhagen Light Rail is also part of the wider public transport network outside the centre. A short visit focused on central Copenhagen can usually rely on the Metro, buses and trains, while Rejseplanen will include the light rail automatically when it is the best connection for an outer destination.

Harbour buses — seeing the city from the water

The yellow harbour buses, or Havnebus, are public transport rather than sightseeing boats. They accept regular zone tickets and City Passes and follow the harbour between places such as Nyhavn, the Royal Library area, Refshaleøen and Nordhavn. Route 991 runs south and 992 runs north; when there is an evening performance at the Opera, route 993 may shuttle between Nyhavn and the Opera House.

A harbour bus is not always the fastest route on land. It is, however, a way to read Copenhagen from the water: the Black Diamond, harbour housing, the Opera House and former industrial areas appear as one continuous urban landscape. For anyone interested in architecture, public space and waterfront regeneration, it offers a different kind of city tour without the price of a sightseeing cruise.

Boarding and leaving takes place via a ramp, making the harbour bus accessible to wheelchair users. Departures are less frequent than Metro trains, and weather or the time of day can affect waiting time, so check Rejseplanen before walking to the harbour.

From the airport — choosing between M2 and regional trains

Public transport at Copenhagen Airport is concentrated around Terminal 3. The city centre is approximately 15–20 minutes away by Metro or regional train. Since both use the same zone-based system, the practical question is not which is cheaper but which station is closer to your accommodation.

  • Choose M2 for Christianshavn, Kongens Nytorv, Nørreport and Frederiksberg.
  • Choose a regional train for København H, Østerport, or onward travel across Zealand, Denmark or Sweden.
  • Consider the 5C when your destination lies on a bus corridor away from a rail station and avoiding a transfer is more important than speed.

Ticket machines are available at the airport. Buy a Single Ticket by entering your destination, or consider City Pass Small if you will travel repeatedly in the city and need airport coverage. If you plan to use an app, install it and set up payment before leaving home, but activate or purchase the actual ticket only when you are ready to travel.

Choosing a ticket — Single Ticket, City Pass or Rejsekort app

For visitors, ticket choice becomes clear when you start with the number of journeys and the area you intend to cover. The table below reflects official information available in September 2026. Prices and terms can change, so the official app or website takes priority at the time of purchase.

ProductBest forCoverage and price guide
Single TicketOnly a few public transport journeysMinimum two zones; adults from DKK 24. Valid across modes within the purchased zones and time.
City Pass SmallRepeated travel around the city and to the airportZones 1–4, 24–120 hours; adults DKK 100–340.
City Pass LargeTrips to Hillerød, Helsingør, Roskilde and the wider regionZones 1–99, 24–120 hours; adults DKK 200–680.
Rejsekort appPaying as you go when the number of trips is uncertainCheck in and out; adults from DKK 22 for two zones, with a 20% off-peak discount where applicable.
COPENHAGEN CARD DISCOVERCombining museums and attractions with transportPublic transport in zones 1–99 plus included attractions; airport travel is included.

City Pass covers buses, trains, the Metro, harbour buses and the relevant light rail within its validity area. Small is generally enough for the city and airport; Large is worth considering when a trip to Louisiana or northern Zealand is part of the plan. COPENHAGEN CARD is an attraction product as well as a transport pass: DISCOVER includes regular public transport and airport travel, while HOP is based on Hop-on Hop-off sightseeing buses and should not be confused with the city’s normal network.

The Rejsekort system changed in 2026. The physical Rejsekort closed on 29 June, and travellers now use the Rejsekort app for check-in and check-out or a Basiskort when they do not want to use an app. For a short visit, Rejsebillet’s Single Ticket or City Pass is simpler; when the amount of travel is unpredictable, the Rejsekort app can be the more flexible option.

Before boarding — using Rejseplanen and Rejsebillet

Use Rejseplanen to plan the journey and Rejsebillet to buy the ticket. Rejseplanen combines Metro, bus, train, harbour bus and light rail data and uses live information to show routes, departures, changes and walking sections. It can search by address or attraction, so you do not need to know the nearest station in advance.

Rejsebillet is available in Danish and English and sells Single Tickets and City Passes. A Single Ticket is normally valid from the time of purchase, so buy it shortly before boarding rather than hours earlier at the hotel. The app shows the remaining validity time. If you prefer not to use a phone, ticket machines are available at Metro stations, major railway stations and the airport.

With the Rejsekort app, swipe to check in before boarding the first vehicle and swipe to check out when the journey ends. You do not check in again when changing from bus to Metro during the same journey. Keep the phone charged: a dead battery can leave you unable to show your travel authority.

Do not assume that a station reader accepts an overseas Visa or Mastercard as a universal tap-in fare. The official options are to have a valid ticket in an app, buy one from a machine, or check in correctly with the Rejsekort app or Basiskort. It is not the same system as bank-card tap-in on the London Underground.

Children, bicycles and inspection — the final practical rules

One passenger aged 16 or over with a valid adult ticket may bring up to two children under 12 free of charge. Children travelling alone pay a child fare until they turn 16, normally half the adult fare. Most stations have lifts or escalators for prams, but check live service information when a lift or station is being repaired.

Bicycles are generally free on S-trains, buses and harbour buses in the Copenhagen City Area, subject to available space. On buses, the driver decides whether there is room, and prams or mobility aids have priority. A bicycle ticket is required on the Metro and regional trains. Bikes are not permitted on the Metro during weekday rush hours, 07:00–09:00 and 15:30–17:30.

Many Copenhagen stations have no physical gate, but ticket inspections take place on vehicles and at stations. Have the valid ticket ready on your phone or as a paper ticket before entering. Travelling without a valid ticket can result in a fine of at least DKK 750. “I will buy one later” or “I have a credit card” is not a substitute for a valid travel document.

Before setting off, check four things: destination, direction, required zones and expiry time. Once those are clear, there is no need to treat the Metro, bus, train and harbour bus as separate systems. Their integration with walking and cycling is part of what makes Copenhagen easy to navigate. Taking public transport is not only a way to reach a destination; it is also a way to experience the city’s design.
