✦ Top pick
Helsingør (Kronborg Castle) is the best all-rounder; choose the Louisiana Museum for art lovers, Malmö if you want to tick off Sweden, and Dragør if you want the closest, easiest escape.
Copenhagen is one of Europe's easiest cities to escape for a day. Denmark's regional trains are fast, frequent, and reliable, and a single Øresund train can have you in another country (Sweden) in about 35 minutes. Within an hour or so you can reach Renaissance castles, a UNESCO cathedral, the world's best-preserved Viking ships, and chalk cliffs over a turquoise sea.
These eight trips are ranked for the traveler who wants the most reward for the least faff: each is reachable by public transport, doable in a day, and worth the ticket. We flag the travel time and mode from Copenhagen Central (København H), what to see, and who each one suits.
If you only have time for one, start at the top. If you want variety across a few days, mix a castle, a museum, and the Sweden crossing for contrast.

1tours from $122.6Helsingør and Kronborg Castle Google
Helsingør is the classic Copenhagen day trip: a handsome old harbor town crowned by Kronborg, the moated Renaissance fortress Shakespeare immortalized as Elsinore in Hamlet. The UNESCO-listed castle guards the narrowest point of the Øresund strait, with cannon-lined ramparts staring across at Sweden and casemates below where the legendary sleeping figure of Holger Danske waits. Beyond the castle, the striking M/S Maritime Museum sits in a former dry dock, and the cobbled old town has good cafes and the medieval Sankt Olai Cathedral. It pairs naturally with a quick ferry hop to Helsingborg in Sweden if you want two countries in a day.
- Kronborg Castle ramparts and casemates
- M/S Maritime Museum of Denmark
- Helsingør's cobbled old town and Sankt Olai Cathedral
- 20-minute ferry to Helsingborg, Sweden

2tours from $214.65Roskilde Google
Denmark's former capital is a compact, easy half-day that punches above its weight. The twin-spired Roskilde Cathedral, a UNESCO World Heritage Site, is the burial church of Danish monarchs, with around 40 royal tombs spanning a thousand years. Down on the fjord, the Viking Ship Museum displays five original 11th-century vessels excavated from the water, plus a working boatyard where shipwrights build replicas with traditional tools. In summer you can sail the fjord on a reconstructed Viking boat, and the town itself has a lively market square and good lunch spots.

- Five original Viking ships at the Viking Ship Museum
- Summer Viking boat sailing on the fjord

3tours from $124.94Malmö, Sweden Google
Crossing into Sweden for the day is one of Copenhagen's signature experiences, and the Øresund train makes it almost effortless. Malmö rewards you with the twisting Turning Torso skyscraper, the cobbled squares of Lilla Torg and Stortorget, and Malmöhus, Scandinavia's oldest surviving Renaissance castle. The Western Harbour (Västra Hamnen) has a sleek waterfront promenade and the Ribersborg beach for summer swims. It is an easy add to pair with the cathedral town of Lund, 15 minutes further on. Remember to bring your passport or ID, as there are border checks.
- The Turning Torso and Western Harbour waterfront
- Lilla Torg and Stortorget old-town squares
- Malmöhus Castle
- Easy add-on to nearby Lund
Best for travelers wanting to tick off a second country
Getting there About 35-40 minutes by Øresund train from København H over the bridge; carry ID for border control
4Louisiana Museum of Modern Art, Humlebæk Google
Often called one of the most beautifully sited museums in the world, Louisiana spreads through a 19th-century villa, glass-walled galleries, and a sculpture park sloping down to the Øresund. The collection runs from Giacometti and Warhol to major rotating exhibitions, but the building and grounds are half the pleasure, with Calder mobiles and Henry Moore figures framed against the sea and Sweden on the horizon. The cafe terrace is a destination in itself for lunch with a view. Allow at least three hours; many visitors stay the whole afternoon.
- Sculpture park overlooking the Øresund
- Giacometti gallery and rotating world-class exhibitions
- Calder and Henry Moore works on the lawns
- The seaside cafe terrace
Best for art lovers and a relaxed cultural afternoon
Getting there About 35 minutes by train from København H to Humlebæk, then a 10-minute signposted walk; roughly 110 DKK each way
5Hillerød and Frederiksborg Castle Google
Frederiksborg is Denmark's grandest castle, a sprawling red-brick Renaissance palace built across three islets on a lake by King Christian IV. Inside, the Museum of National History fills room after gilded room with portraits, the spectacular Great Hall, and the chapel where Danish kings were once crowned. The Baroque gardens behind the castle, with their terraced parterres and mirror-image canals, are free to wander and gorgeous in summer. A small ferry crosses the castle lake, and the whole visit pairs well with a stroll through Hillerød's pedestrian center.
- Frederiksborg Castle and the Museum of National History
- The gilded Great Hall and chapel
- Baroque terraced gardens
- Boat across the castle lake
Best for castle and history enthusiasts
Getting there About 40 minutes on the S-train (line A or E) from København H to Hillerød, then a short bus or 20-minute walk
6Dragør Google
The closest and easiest escape on this list, Dragør is a preserved fishing village of yellow-washed cottages, hollyhocks, and crooked cobbled lanes right on the Øresund. It feels centuries removed from the city yet sits a short bus ride from the airport. Wander the car-free old town, watch boats in the working harbor, and eat fresh fish or smørrebrød at a quayside restaurant. With low effort and a quick journey, it is ideal for a half-day or a sunny afternoon stroll.
- Car-free old town of yellow cottages
- Dragør harbor and fish restaurants
- Coastal walks along the Øresund
- Dragør Museum on local maritime history
Best for a quick, low-effort half-day and a stroll
Getting there About 35-40 minutes from central Copenhagen by Metro to the airport then bus 35, or direct bus 250S; standard city transport ticket
7Møns Klint Google
For Denmark's most dramatic scenery, Møns Klint delivers gleaming white chalk cliffs plunging more than 100 meters to a turquoise sea, fringed by ancient beech forest. Wooden staircases descend to the pebble beach below, where fossil hunters dig for sea urchins and belemnites, and the GeoCenter Møns Klint explains the geology. The surrounding island of Møn is a designated Dark Sky reserve with quiet roads and the medieval frescoes of Elmelunde and Keldby churches. It is the longest trip here and best with a car, but the payoff is the country's finest coastal walk.
- White chalk cliffs and the clifftop forest trails
- Fossil hunting on the beach below
- GeoCenter Møns Klint
- Møn's Dark Sky reserve and medieval church frescoes
Best for hikers, nature lovers, and photographers

8Lund, Sweden Google
One of Scandinavia's oldest towns and home to a venerable university, Lund is a calm, scholarly counterpoint to Malmö and easy to reach on the same line. Its centerpiece is the 12th-century Lund Cathedral, a Romanesque masterpiece with an astronomical clock that puts on a small mechanical show twice daily. The cobbled streets are dotted with student cafes, bookshops, and the open-air Kulturen museum of historic Nordic buildings. Compact and walkable, it makes a serene half-day on its own or a natural pairing with Malmö.
- Romanesque Lund Cathedral and its astronomical clock
- Kulturen open-air museum
- Cobbled university-town streets and cafes

✦ Good to know
Before you go
Tickets and passesMost of these trips run on the integrated DOT zone system; buy tickets via the DOT Tickets or DSB app. For Sweden, the Øresund train to Malmö and Lund is a separate cross-border ticket, and you must carry a passport or national ID for border checks.
When to goMay to September is best for gardens, cliff walks, and Viking boat sailings, many of which only run in summer. Castles and museums stay open year-round but check seasonal hours, especially Møns Klint's GeoCenter.
Booking aheadTrains rarely need pre-booking, but reserve castle or museum entry online in peak summer to skip queues. Guided full-day tours are worth booking a few days ahead in July and August.
Combine destinationsHelsingør pairs with the Louisiana Museum (both on the northern coastal line), and Malmö pairs with Lund (15 minutes apart). Planning two nearby stops makes the most of a single train ticket.
From royal castles and Viking ships to chalk cliffs and a bridge into Sweden, Copenhagen's surroundings pack a remarkable amount of variety into short, simple journeys. Pick one for a day or string a few together over a long weekend, and you will see a side of Denmark that the city alone can't show. Check the train times, pack your ID for Sweden, and go.
