Day Trips from Copenhagen: Train, Boat, Bike and Cross-Border

I had one spare day at the end of my time in Copenhagen, and I spent a stupid amount of it just staring at the departures board at the central station, trying to decide. That’s the thing about Copenhagen that nobody quite prepares you for: it isn’t only a great city, it’s a great launchpad. A normal commuter train will drop you in another country before lunch. In the end, I picked Malmö, walked onto an Øresundståg, and was standing in Sweden about 35 minutes later, slightly amazed that crossing an international border had cost me less than a decent dinner.

I’ve been to Copenhagen and made the Malmö crossing myself, and I can talk about those two from experience. Everything else is researched rather than firsthand, the options on that departure board, the trips I read up on, and I asked locals about. I’ve kept the honest verdicts in, including the trips people oversell. Some are genuine 25-minute hops.  

Here’s how to actually do it: by train, by boat, by bike, and across three borders.

Getting to Your Day Trip: Train, Bus, Car and Tours

Copenhagen is one of the easiest cities in Europe to leave for the day, mostly because the rail network does the heavy lifting.

By train. Danish State Railways (DSB) covers the local trips in Zealand: Roskilde, Helsingør, Hillerød, Humlebæk. And the Øresundståg trains run across the bridge into Sweden. You can pay with a contactless card on the regional Zealand routes, buy singles from the DSB app, or use a Rejsekort travel card. For cross-border and longer routes, I’d compare fares on Omio, which pulls DSB, Øresundståg, and the German and Swedish operators into one search.

By bus. For the longest hauls (Hamburg, Gothenburg) FlixBus is the budget option. It’s slower than the train, and the savings aren’t always huge once you factor in the hours, so check both before booking.

By car. A rental gives you the cliffs and the deer parks that public transport handles badly. Just know the Øresund Bridge toll is steep (a one-way car crossing runs well over 500 DKK), so for a solo trip to Malmö, the train wins easily. Cars only make sense here for nature and for groups.

By an organized tour. If you’d rather someone else handle the logistics, GetYourGuide and Viator both run day tours to Kronborg, the cliffs, and Sweden. You pay for the convenience and lose the freedom to pause, but for the harder-to-reach nature spots, they can be worth it.

Best Day Trips from Copenhagen by Train (in Denmark)

You don’t need to cross a border to get a brilliant day out. These are the local Zealand trips, all reachable on a single DSB ticket, with most under an hour away.

Roskilde: Vikings and a Thousand-Year-Old Cathedral

About 25 minutes west of Copenhagen, Roskilde was the Danish capital for centuries, and it still has the receipts to prove it. The red-brick cathedral is a UNESCO site and the burial place of Danish royalty going back to the 1400s. The real draw, though, is the Viking Ship Museum, built around five original 11th-century vessels deliberately sunk in the fjord to block invaders. Worth knowing before you go: part of the museum’s waterfront has been affected by flood-protection works, so check what’s open before you travel. Entry to the ship hall is around 160 DKK in high season. The town itself is small and walkable, which makes Roskilde one of the easiest half-day trips on this list.

Helsingør and Kronborg: the Castle Shakespeare Never Saw

Forty-five minutes up the coast sits Helsingør, and its star attraction is Kronborg — the Renaissance fortress Shakespeare used as the setting for Hamlet without ever visiting it. It guards the narrowest point of the Øresund Strait, close enough to Sweden that you can see Helsingborg across the water. Reviews consistently flag the casemates, the dark underground tunnels where a statue of the sleeping Norse hero Holger Danske waits to wake when Denmark is in danger. Castle entry is roughly 165 DKK. Pair it with the M/S Maritime Museum next door, cleverly built into a dry dock, and you’ve got a full day without ever feeling rushed.

Hillerød and Frederiksborg: Denmark’s Answer to a Water Palace

If Kronborg is the brooding fortress, Frederiksborg in Hillerød (around 40 minutes by train) is the show-off. Built across three islets on a lake, it’s a 17th-century palace that now houses the Museum of National History. The baroque gardens are free to walk and arguably the best reason to come, wide symmetrical terraces reflected in the water, with the palace as the backdrop. Museum entry runs about 90–100 DKK, which is good value for what’s inside. Of the three castle trips, this is the one travelers most often call the prettiest.

Humlebæk and the Louisiana Museum of Modern Art

This one’s for anyone who, like me, will reroute an entire trip around a good museum. Louisiana sits on the coast at Humlebæk, about 35 minutes north of Copenhagen, and it’s regularly named one of the best modern art museums in the world. What makes it special isn’t only the collection: Giacometti, Calder, a rotating roster of major exhibitions, but also the setting. The galleries open onto a sculpture garden running down to the sea, with Sweden visible on the horizon. Entry is around 160 DKK. Even on a grey day, the building and the view do half the work.

Dragør: the Old Fishing Town Hiding Next to the Airport

For the shortest trip on this list, take a bus from the city out to Dragør, a preserved fishing village of yellow houses and crooked lanes right on the edge of Copenhagen, barely beyond the airport. There’s no big-ticket attraction here, and that’s the point as it’s an hour of wandering, a harbor, smoked fish, and almost no crowds. If you want a half-day that feels like proper Denmark without committing to a train journey, this is it.

Odense: Hans Christian Andersen’s Hometown

I’ll be straight with you: at around 1 hour 15 minutes each way, Odense is the longest Danish day trip and the one I’d only do if you’re genuinely interested in Hans Christian Andersen.  Denmark’s third-largest city, where he was born, and the modern HCA museum dedicated to him has had strong reviews for the way it tells his story. The old town around it is pretty, and the trip is easy by direct train. Just go in knowing you’ll spend nearly three hours on rails for it.

Day Trips from Copenhagen to Sweden

This is where Copenhagen earns its reputation. The Øresund Bridge means Sweden is closer than half the Danish countryside, and crossing it remains the single most memorable easy thing I did on my whole trip.

Malmö: the Easiest Border Crossing you’ll Ever Make

I almost didn’t go. I assumed crossing into another country would take he whole day in logistics. It absolutely did not. The Øresundståg from Copenhagen Central runs every 20 minutes or so, the crossing takes around 35–40 minutes, and a single ticket cost me somewhere around 100–120 DKK. Half of that ride is the bridge itself: water on both sides, the wind farm turning, and then you’re simply in Sweden.

Malmö surprised me by being quietly confident rather than trying to impress anyone. I spent the afternoon between the old town squares, Stortorget and the smaller Lilla Torg, and the Turning Torso, the twisting white skyscraper on the waterfront that’s become the city’s signature. What stuck with me was how relaxed it felt after Copenhagen’s busier center. Prices are in Swedish kronor here, not Danish, and tap a card for transport rather than fumbling with cash. One honest note: carry your passport or national ID. Sweden has reintroduced border ID checks on and off in recent years, and while I wasn’t stopped, you don’t want to be the person who gets turned around at the bridge.

Lund: a University Town with a 900-Year-Old Cathedral

Fifteen minutes past Malmö (so around 50 minutes from Copenhagen) is Lund, one of Scandinavia’s oldest towns and home to a major university. The Romanesque cathedral is the headline, go on the hour to catch its astronomical clock, and the surrounding streets have the calm, bookish feel of a place run by students rather than tourists. It pairs neatly with Malmö if you want two Swedish towns in one day.

Helsingborg: the Two-Castle Crossing

Here’s a clever trick. Instead of returning from Helsingør the way you came, take the 20-minute ferry across the strait to Helsingborg in Sweden. You get a short sea crossing, a second medieval tower (Kärnan) to climb for the views back toward Denmark, and the satisfaction of having done two countries in an afternoon. It’s one of the more underrated cross-border combinations from Copenhagen.

Gothenburg: Doable but I’d Take 2 Days

Gothenburg shows up in “best day trips from Copenhagen to Sweden” lists, and technically, you can do it as the train runs around 3 to 3.5 hours each way. But that’s six or seven hours of travel for a few hours in the city, and Gothenburg deserves better than a sprint. My honest take: make it an overnight, not a day trip. If you only have a day for Sweden, spend it in Malmö and Lund.

Day Trips from Copenhagen to Germany

Germany is the long-haul direction, and what’s possible here changed recently, so it’s worth getting the facts straight.

Hamburg: a long day, not a quick one

The Copenhagen–Hamburg train no longer rolls onto a ferry the way it famously used to,  since 2019, the route runs overland via Odense and Flensburg, while the Fehmarn Belt tunnel is being built (it won’t open until around 2028–2030). The direct trains now take roughly 4.5 to 5 hours each way, with new ComfortJet and EuroCity Express services running the line. Tickets booked ahead of time can start surprisingly cheap. Can you day-trip it? Just barely, on the earliest train out and the last one back, but you’ll get maybe five or six hours in Hamburg for nine or ten on the rails. I’d treat Hamburg as an overnight and enjoy the harbor, the Elbphilharmonie, and the Speicherstadt warehouse district properly.

Lübeck: the marzipan city, slightly further still

If you do overnight in Hamburg, Lübeck is a brilliant add-on, a UNESCO-listed old town on an island, the home of Niederegger marzipan, and the famous twin-towered Holstentor gate. From Copenhagen, it’s too far for a day, but from a Hamburg base, it’s only about 45 minutes. File this one under “extend the trip,” not “day trip.”

Can you Take a Day Trip to Norway from Copenhagen?

Short answer: not really, and anyone selling you a Copenhagen-to-Oslo day trip is stretching the truth.

Oslo is too far for a return train or bus in a day. Your two real options are a flight about 1 hour 15 minutes in the air, plus airport time at both ends or the overnight cruise, which I’d actually recommend if Norway is calling. The Copenhagen–Oslo ferry (now run by Go Nordic Cruiseline, the route DFDS operated until late 2024) sails in the evening and arrives the next morning, roughly 17.5 hours of crossing dressed up as a mini-cruise, with cabins, buffets, and onboard entertainment. For the price of a hotel room, you get a bed, dinner, and Denmark and Norway sliding past the window. It’s a lovely way to reach Oslo. It is not a day trip, and I’d rather tell you that than pretend otherwise.

Nature Day Trips from Copenhagen

Most of Copenhagen’s best nature needs a car or a bit of patience on public transport, so I’ve grouped the standouts here rather than stretching each into its own section. Worth the effort: 

• Møns Klint, the dramatic white chalk cliffs about two hours south, plunging into turquoise sea genuinely spectacular, but awkward without a car (train plus a seasonal bus, so check connections before you commit). 
• Stevns Klint, a UNESCO-listed cliff line closer to the city, where the geology records the asteroid impact that ended the dinosaurs. 
• Dyrehaven, the royal deer park at Klampenborg, reachable in about 20 minutes by train and home to thousands of free-roaming deer, ancient oaks, and the old Bakken funfair on its edge easily the most accessible nature day out on this list.

The Best Day Trips in Winter

Half of these trips lose their shine in a Danish January, when the light fades by mid-afternoon, and the cliffs and bike routes turn bleak. So in winter, lean indoors. Kronborg, Frederiksborg, and the Louisiana museum are all weatherproof and arguably more atmospheric under grey skies. Malmö and Lund work year-round, and Roskilde’s cathedral and Viking hall keep you mostly under cover. Save the cliffs and the cycling for the long days of summer, they’re worth waiting for.

A Few Things Worth Knowing Before you Go

A handful of practical notes that will save you hassle. 

• Carry a photo ID or your passport for any trip into Sweden, since border checks come and go. 
• Denmark uses Danish kroner, and Sweden uses Swedish kroner, so don’t assume a single card setup covers both, though tapping a contactless card works almost everywhere. 
• For the local Zealand trips, the DSB app or a Rejsekort is simplest; for cross-border and German routes, compare fares on Omio first. 
• And book the longer trains (Hamburg, Gothenburg) in advance, where the cheap fares live, turn up on the day, and you’ll pay a lot more.
