Getting around Denmark: trains, buses, driving and domestic flights

Denmark is small and its rail spine is good, so most trips need no car. Use DSB trains between cities, the metro, S-train and bike inside Copenhagen, and buses for the last stretch to villages and beaches. Book early for the cheapest fares, and reserve a seat if you travel on a Friday or Sunday afternoon.

DSB runs the InterCity and faster IC Lyn services on the main lines: Copenhagen–Odense, Copenhagen–Aarhus–Aalborg, and across to Esbjerg and Sønderborg. Trains are frequent, have Wi-Fi and quiet coaches, and the standard is high. Buy in the DSB app or on dsb.dk; an Orange or early-booking ticket is much cheaper than a walk-up fare, but it is tied to a specific departure.

Seat reservations are optional on most services and cost about DKK 30. On Friday and Sunday afternoons, and around holidays, the busy Copenhagen–Aarhus trains fill, so a reservation is worth it. Regional trains and the Copenhagen S-train need no reservation at all — just tap in with a Rejsekort, an app ticket or a contactless card where accepted.

Bikes travel free on S-trains and on many regional trains; on InterCity services you need a bike ticket and a reserved space, so check before you roll up to the platform.

Long-distance buses from FlixBus and Kombardo Expressen undercut the train on the main routes, often at DKK 100–250 if you book ahead. The trade-off is time — about 3 h 30 for Copenhagen–Aarhus — and stops that can sit outside the town centre rather than at the station. Buses generally do not take bikes.

Local and regional buses fill the gaps the rail network leaves: the west coast, small islands, and villages between stations. They are frequent enough on weekdays, thinner on Sundays and public holidays. A Rejsekort or the Rejseplanen app covers buses and trains in one ticket.

A hire car makes sense for the places trains do not reach well: the Skagen and west coast beaches, Møn and its chalk cliffs, rural Funen, and Bornholm's back roads. Expect DKK 400–800 a day plus fuel, and the Great Belt Bridge toll of about DKK 270 each way. Parking in Copenhagen and Aarhus is expensive and mostly app-based, and both cities have low-emission zones, so check your rental's status before driving in.

Denmark drives on the right, speed limits are strictly enforced, and headlights must be on at all times. Drink-driving limits are low. If you only plan city time plus one or two big towns, skip the car and take the train; rent one only for the days you actually leave the rail network.

Bikes are how Danes move, and renting one is the best way to see Copenhagen, Aarhus and Odense. Expect DKK 100–200 a day for a rental, or a city bike charged by the minute. Lanes are wide, separated and respected, and drivers actually look for cyclists.

Two rules matter: lights are required after dark, and fines apply for riding on pavements or through red lights. Bikes ride free on S-trains, which makes a bike-plus-train day trip easy. Long-distance cycle routes cross the country, and many hotels and hostels have secure parking.

Ferries are the only way to reach several islands. Bornholm is served from Ystad in Sweden in 1 h 20 and from Køge in about 3 h 30; foot passenger fares run DKK 150–400. Ærø, Samsø and the islands south of Funen have their own short crossings. In summer, car spaces sell out well ahead — book the car early or walk on and rent locally.

Domestic flights are rarely faster than the train on the mainland, but they matter for Bornholm (about 35 minutes from Copenhagen), Aalborg, Karup and for connecting to long-haul flights at CPH. Fares run DKK 500–1,200. For almost every other city pair, the train wins door to door.

There is no single national rail pass aimed at visitors the way some countries have one; the cheapest strategy is usually early-booking DSB tickets plus a Rejsekort or app tickets for local travel. A Rejsekort is a tap card that gives a discount on single journeys across buses, trains and metro, and the DSB or Rejseplanen apps sell the same tickets on your phone.

In Copenhagen, a 24- or 72-hour city pass covers the metro, S-train, harbour bus and city buses in the zones you choose; the Copenhagen Card bundles transport with museum entry and is worth it only if you plan several paid sights. For a longer stay, a Rejsekort or a monthly commuter product beats single tickets. Check current zone prices before you buy.

Denmark is compact and punctual, so build in less slack than you would elsewhere — but do check for engineering works on weekends, when replacement buses add time. Public holidays thin out buses and regional trains, and some island ferries run a reduced winter timetable.

Tap water is excellent everywhere, so refill a bottle rather than buying water. Card and MobilePay are accepted almost universally, including on buses and at ticket machines, so you rarely need cash. If you are arriving by air, the metro or train reaches central Copenhagen in about 15 minutes.
