Copenhagen's transport network is one of the most liveable in Europe: a driverless 24-hour metro, a reliable S-tog suburban rail system, excellent buses, a harbour bus ferry service, and a city where cycling is not just encouraged but taken completely for granted as a normal way to travel. Combine a few of these and you can move around the city without a car, at almost any hour.
The Metro: driverless and 24-hour
Copenhagen's Metro is fully automated — no driver in the cab — and one of its most visitor-friendly features is that it runs 24 hours a day, seven days a week. Frequency varies (every 2–4 minutes at peak, every 20 minutes in the small hours), but you are never stuck waiting for morning. Two main lines form the backbone, with a third adding coverage:
- M1 and M2 — share a common central section from Vanløse (M1) and the Airport (M2) through Frederiksberg and the city centre (Kongens Nytorv, Copenhagen Central Station, Christianshavn), before splitting at Vanløse and the airport ends. M2 is the direct airport link.
- M3 (Cityringen) — the circular metro line, opened in 2019, looping around the inner city and serving neighbourhoods like Nørreport, Frederiksberg and Østerport that the older lines did not reach. It adds significantly to network coverage and is especially useful for the Meatpacking District (Kødbyen) and the lakes area.
- M4 — opened in stages from 2020, extending the network to the Copenhagen Harbour area (Orientkaj) and with a branch toward the new Sydhavn district.
The key interchange in the city centre is Kongens Nytorv (M1/M2 and regional bus connections) and Nørreport, where the M3 meets the S-tog network — the busiest transit hub in Denmark.
The S-tog: suburban rail
The S-tog (S-train) is a suburban rail system running on dedicated tracks, marked on maps by the distinctive red hexagonal S logo. Seven lines (A through H, minus F and G) radiate from Copenhagen Central Station and Nørreport out through the inner and outer suburbs, and along the coast to the north (the famous Kystbanen "coastal line") and south toward Roskilde. The S-tog does not go to the airport — that is the Metro M2.
The S-tog is the fastest way to reach western Copenhagen, Hellerup, the northern beach towns of Charlottenlund and Klampenborg, and suburban centres like Lyngby. It runs from around 5 am until around 12.30 am on weekdays, with night buses filling the gap on most nights.
Regional trains (Øresundtåg and DSB)
From Central Station and Nørreport, DSB regional trains extend beyond the S-tog network — to Helsingør (for the Kronborg Castle ferry to Sweden), Roskilde, Køge and across the Øresund Bridge to Malmö in Sweden. The Øresundtåg services to Malmö take around 35–40 minutes from Central Station and form one of the most seamlessly cross-border commuter routes in Europe. They accept the same Rejsekort (travel card) as city transport within zones.
Buses
Movia operates Copenhagen's buses, which cover areas outside the metro and S-tog lines as well as providing more direct surface routes between points on the map. The distinctive yellow buses are reliable but can be slow in city traffic. Express routes (prefixed "A" for rapid lines) stop less frequently and are faster. Night buses run on key routes when other services finish.
The Harbour Bus (Havnebus) routes 991 and 992 run along the Copenhagen waterfront, connecting the Opera House, the Royal Library (Black Diamond), Nyhavn, the S-tog at Nordhavn and the Nordre Toldbod area. It is an enjoyable and genuinely useful alternative to the metro for waterfront destinations — and tickets are the same as any other Movia service.
Tickets and the Rejsekort
Copenhagen's ticketing is zone-based, but visitors are well served by a simple set of options:
- Single tickets: priced by number of zones crossed. A central city trip typically spans one to two zones. Buy at metro stations, at DSB machines or via the DOT Tickets app.
- 24-hour pass: unlimited travel within chosen zones for 24 hours. The all-zones variant covers the airport, outer suburbs and even the Øresund crossing to Malmö.
- 72-hour and 120-hour (City Pass): excellent value for multi-day visitors; the Copenhagen City Pass covers all zones including the airport metro.
- Rejsekort: a rechargeable travel smartcard that gives a per-trip discount over single tickets. Requires a deposit and must be registered online. Ideal for stays of a week or more, or for frequent visitors.
- Copenhagen Card: a tourism-oriented pass including unlimited transport plus free entry to most museums and attractions; worth calculating carefully against your planned itinerary.
Validate tickets or tap the Rejsekort on yellow readers at metro gates, on-board bus validators, and S-tog gates. Remember to tap out on the Rejsekort at the end of each journey — failure to do so results in a maximum-zone charge.
Cycling in Copenhagen
Cycling is not a niche activity in Copenhagen — an estimated 40–50% of residents commute by bike daily, and the city's infrastructure is built around it. Wide, separated cycle lanes run throughout the city, with their own traffic lights and right-of-way logic. Visitors comfortable on a bicycle will often find it the fastest and most enjoyable way to cross the city centre.
The Bycyklen (city bike) smart bike-share scheme operates electric-assist bikes from docking stations across the city. Registration is via the app; rental charges are by the hour. Standard bikes can also be taken on S-tog trains (not metro) for a small surcharge outside peak hours.
For the waterfront, Nørrebro, Vesterbro and Frederiksberg, cycling is genuinely the locals' choice. The main cycling corridor — the Cykelslangen (Cycle Snake) elevated bike bridge over the harbour — is worth crossing for the experience alone.
Tips for getting around Copenhagen
- The Metro's 24-hour service means you never need to worry about last trains from the city centre on a late night out.
- Nørreport is the central nerve point of the network — Metro M3, S-tog, and multiple bus routes all converge here. If you are ever unsure of the fastest route, Nørreport is usually the right direction.
- The Rejsekort must be tapped off at journey's end — many visitors forget and get charged the maximum fare.
- For trips to Sweden, the Øresundtåg from Central Station to Malmö is efficient and scenic over the famous bridge. Check whether your pass or Rejsekort balance covers the international portion.
- For longer Scandinavian journeys, see European rail passes and the Schengen rules if you plan to travel between several Nordic countries on one trip.
Frequently asked questions
Does the Copenhagen Metro run all night?
Yes. All metro lines — M1, M2, M3 and M4 — run 24 hours a day, seven days a week. Frequency is lower in the small hours (around every 20 minutes) but service does not stop.
How do I get from Copenhagen Airport to the city centre?
The M2 metro runs directly from the airport to the city centre in 14–16 minutes. Trains run around the clock. You need a ticket covering zones 1–3, or a City Pass / all-zones day pass.
Can I travel to Malmö by public transport from Copenhagen?
Yes. Øresundtåg trains run from Copenhagen Central Station (and Nørreport) to Malmö Central in around 35–40 minutes, crossing the Øresund Bridge. Services are frequent throughout the day. A Rejsekort covers the Danish portion; you pay separately for the Swedish side, or use a through ticket.
Is the Bycyklen bike share worth using?
For visitors comfortable on a bicycle, yes — especially for exploring the inner city, waterfront and parks where bikes are faster than the metro. The electric-assist option makes hill-free Copenhagen even more effortless. Check the Bycyklen app for available docking spots, as popular stations can run low in peak hours.
