1. Experience Tivoli Gardens

Opened in 1843, Tivoli Gardens is one of Copenhagen's defining attractions. Rather than functioning solely as an amusement park, Tivoli combines rides, landscaped gardens, restaurants, concerts and theatrical performances directly beside Copenhagen Central Station.

Among the most memorable things to do in Copenhagen is visiting in the evening, when thousands of lights transform the gardens. The historic wooden Roller Coaster dates from 1914, while newer rides provide considerably more intense thrills.

Tivoli changes with the seasons. Its 2026 summer season runs from April 7 to September 20, with concerts, ballet performances and other entertainment scheduled throughout the period. Seasonal Halloween and Christmas openings create completely different atmospheres later in the year.

Allow at least three hours, or an entire evening if you plan to enjoy rides and dinner.

2. Walk Along Colorful Nyhavn

Nyhavn is the postcard image many travelers immediately associate with Copenhagen. The waterfront is lined with brightly painted historic townhouses, restaurants, cafés and wooden vessels.

This former commercial port once welcomed sailors and ships from around the world. Today, its colorful 17th-century buildings make it one of the most recognizable Copenhagen attractions. Hans Christian Andersen also lived at several addresses around Nyhavn during his life.

Walking beside the canal costs nothing, and early morning is particularly attractive for photography before the waterfront becomes busy.

Rather than limiting your visit to taking photographs, continue toward the harbor or use Nyhavn as the departure point for a canal cruise. During Christmas, market stalls and festive lights give the area an entirely different character.

3. Explore Rosenborg Castle and the Crown Jewels

For royal history, Rosenborg Castle deserves a prominent position on any list of things to do in Copenhagen.

Christian IV originally had the castle constructed as a summer residence in the early 17th century. Its interiors now provide a fascinating journey through Danish royal history, with elaborate rooms, royal collections and historic objects.

The greatest attraction lies beneath the castle, where visitors can see Denmark's Crown Jewels and royal regalia.

Rosenborg also sits beside the King's Garden, Copenhagen's oldest royal garden. Combining the two works particularly well on a pleasant spring or summer morning.

Allow around 90 minutes for the castle itself, followed by additional time for the gardens. The central location makes it easy to combine Rosenborg with the Round Tower or SMK.

4. Discover Christiansborg Palace

Christiansborg Palace is particularly interesting because it combines royal history with Denmark's modern political life.

The palace stands on Slotsholmen in central Copenhagen and houses the Danish Parliament, the Supreme Court and the Prime Minister's Office. Parts of the complex are also used by the Royal Family for official functions.

Visitors exploring Copenhagen attractions can access several areas, including the Royal Reception Rooms, ruins beneath the palace and Royal Stables, subject to opening arrangements.

The Great Hall is especially memorable because of its large modern tapestries depicting Denmark's history.

The palace tower also provides impressive views across central Copenhagen. Because Christiansborg contains multiple attractions rather than one simple museum route, allow two to three hours if you want to explore it properly.

5. Take a Copenhagen Canal Cruise

A canal cruise provides a completely different perspective on the Danish capital and is one of the easiest answers to what to do in Copenhagen Denmark on a first visit.

The classic sightseeing cruise lasts approximately one hour and passes landmarks including Amalienborg Palace, Christiansborg Palace, the Copenhagen Opera House, Black Diamond and Little Mermaid. Boats depart from Nyhavn and Ved Stranden.

As of the currently published listing, classic tours start at 199 DKK for adults and 100 DKK for children aged 6–15, while younger children travel free. Prices can change, so confirm them before visiting.

Canal tours are especially worthwhile early in a trip because they provide a useful geographical introduction before you explore individual neighborhoods on foot.

6. Visit Amalienborg Palace

Amalienborg Palace is the home of Denmark's royal family and consists of four impressive palaces arranged around an octagonal square.

For travelers interested in monarchy and history, it is among the essential things to do in Copenhagen.

One highlight is the changing of the Royal Guard. The guards leave Rosenborg Castle at 11:30 and march through Copenhagen before the changing ceremony at Amalienborg at noon when the monarch is in residence. The exact form of the ceremony depends on which members of the Royal Family are present.

Visitors can also explore the Amalienborg Museum, which presents royal interiors and objects associated with generations of the Danish monarchy.

Nearby Frederik's Church, commonly called the Marble Church, makes an excellent addition to the visit.

7. Climb the Round Tower

Built during the reign of Christian IV, The Round Tower is one of Copenhagen's most unusual historic structures.

Instead of climbing a conventional staircase for most of the journey, visitors ascend the tower using its famous spiral ramp. The route eventually leads toward an observation platform overlooking Copenhagen's rooftops.

The combination of unusual architecture and city views makes it one of the most distinctive Copenhagen attractions for first-time travelers.

The tower originally formed part of a scholarly complex and remains associated with astronomy; its historic observatory is another reason to explore beyond the viewpoint.

Its location on Købmagergade also makes itinerary planning simple. Strøget, Rosenborg Castle and several central cafés and shops are within comfortable walking distance.

8. Explore the National Museum of Denmark

Travelers wanting to understand Denmark beyond Copenhagen's photogenic streets should spend time at the National Museum of Denmark.

The collections cover thousands of years of Danish and international history, making this one of the most informative things to do in Copenhagen on a rainy or cold day.

The prehistoric and Viking collections are particularly relevant for travelers interested in Scandinavia's early history. Exhibitions also explore medieval Denmark and later periods of Danish society.

The museum is centrally located on Ny Vestergade, close to Christiansborg Palace and Tivoli Gardens, so it fits easily into a sightseeing itinerary.

Allow at least two hours, although history enthusiasts can comfortably spend considerably longer exploring the extensive collections.

9. See Danish and European Art at SMK

SMK – Statens Museum for Kunst is Denmark's National Gallery and the country's largest art museum. VisitCopenhagen specifically identifies it as having an outstanding collection of Danish and international art.

For art lovers deciding what to do in Copenhagen Denmark, SMK offers a valuable break from palaces and waterfront sightseeing.

Its collections span centuries, including European Old Masters, Danish Golden Age art and modern works. This range means visitors can explore both Denmark's artistic development and broader European traditions within one museum.

The museum sits beside Østre Anlæg park and close to Rosenborg Castle and the Botanical Garden, making this area particularly efficient for a full day of cultural sightseeing.

Allow around two hours for a general visit and longer if art is a major focus of your trip.

10. See The Little Mermaid

The Little Mermaid may be small, but it remains one of the most famous Copenhagen attractions.

Inspired by Hans Christian Andersen's fairy tale, Edvard Eriksen's bronze sculpture has occupied its waterfront position at Langelinie since 1913. The statue has become an international symbol of Copenhagen despite being much smaller than some first-time visitors imagine.

Rather than traveling across the city solely for a quick photograph, incorporate the statue into a broader waterfront walk.

A good route connects Nyhavn, Amalienborg Palace, the Marble Church, Kastellet and the Little Mermaid. This transforms a brief photo stop into an enjoyable exploration of Copenhagen's harbor district.

Canal cruises also pass the sculpture, although viewing it from land provides the classic perspective.

11. Walk Through Kastellet

Close to the Little Mermaid, Kastellet offers one of Copenhagen's most distinctive green spaces.

The historic star-shaped fortress dates largely from the 17th century and retains ramparts, military buildings, pathways and a traditional windmill. It remains an active military area while also being open for visitors to walk through.

Exploring the ramparts is one of the quieter things to do in Copenhagen, particularly after visiting the busy waterfront landmarks nearby.

The elevated paths provide attractive views across the fortress and surrounding area, while the grassy landscape feels surprisingly peaceful considering its proximity to central Copenhagen.

Entry to the outdoor fortress area is generally free, making Kastellet particularly useful for budget-conscious itineraries. Combine it with the Little Mermaid and nearby Gefion Fountain.

12. Cycle Around Copenhagen

Copenhagen is best understood from a bicycle. VisitCopenhagen describes cycling as fundamental to everyday life in the city, where residents ride throughout the year in sun, rain and even snow.

Renting a bicycle therefore offers more than transportation—it provides a direct experience of local urban culture.

Cycling can also make geographically dispersed Copenhagen attractions easier to combine. A route might connect Nyhavn, Christianshavn, the harborfront, Frederiksberg and Nørrebro while allowing stops at bakeries, parks and cafés along the way.

Visitors should learn local cycling etiquette before joining busy commuter routes. Keep right, signal before stopping or turning and avoid unexpectedly entering cycle lanes on foot.

For confident cyclists, spending half a day exploring beyond the historic center can reveal a much more local Copenhagen.

13. Visit Copenhagen Zoo

Families wondering what to do in Copenhagen Denmark can dedicate several hours to Copenhagen Zoo in Frederiksberg.

The zoo houses more than 4,000 animals from around the world and ranks among Denmark's most visited attractions.

Its modern Elephant House was designed by renowned architect Norman Foster, while the Arctic Ring and other habitats provide opportunities to see animals in carefully designed environments.

The zoo's location also makes it possible to combine the visit with Frederiksberg Gardens, one of the capital area's most attractive green spaces.

Families should allow at least half a day rather than treating the zoo as a quick stop. It is especially useful when building an itinerary that needs attractions specifically suited to younger travelers.

14. Explore Den Blå Planet

Den Blå Planet, or the National Aquarium Denmark, provides another strong family attraction.

Located in Kastrup between central Copenhagen and the airport, the aquarium is instantly recognizable from its swirling, water-inspired architecture.

Inside, visitors encounter marine environments ranging from tropical ecosystems to colder northern waters. The enormous Ocean Tank and underwater viewing areas are particular highlights.

Among indoor things to do in Copenhagen, the aquarium is especially useful when the weather becomes wet or cold. Its location near Copenhagen Airport also means travelers with later flights may be able to incorporate it into their final day.

Allow approximately two to three hours for the aquarium. Families with children may want longer, particularly when attending scheduled feedings or educational activities.

15. Explore Copenhagen's Harbor, Food and Local Neighborhoods

Not every memorable Copenhagen experience requires an admission ticket. Some of the city's greatest pleasures come from simply exploring its neighborhoods, waterfronts and food culture.

Christianshavn provides canals and historic architecture, Nørrebro offers an energetic multicultural food and café scene, while Vesterbro combines restaurants, nightlife and the regenerated Meatpacking District.

During summer, Copenhagen's harbor becomes particularly important. The official tourism guide highlights harbor swimming, street-food markets and waterfront experiences as central parts of summer life.

For travelers seeking less conventional Copenhagen attractions, spend an afternoon away from the major monuments. Visit a bakery, try smørrebrød, walk beside the harbor, browse independent shops and finish at a food market or neighborhood restaurant.

This slower exploration often reveals Copenhagen's everyday character better than rushing between landmarks.

Best Copenhagen Attractions for First-Time Visitors

The official Copenhagen Card guide is worth checking if your itinerary contains several paid attractions. It currently covers more than 80 attractions and includes public transport throughout the Copenhagen region, including airport travel.

How Many Days Do You Need in Copenhagen?

Three days is a practical minimum for a first visit. Day one can focus on Nyhavn, Amalienborg, the Little Mermaid and a canal cruise. Day two can combine Rosenborg Castle, the Round Tower, Christiansborg and Tivoli Gardens. A third day provides room for museums, neighborhoods, food experiences and cycling.

Four or five days are better if you prefer slower travel or want to explore attractions beyond the city center.

Copenhagen's relatively compact center is a major advantage. VisitCopenhagen notes that many of the city's classic sights are within walking distance, while bicycles, metro services and harbor buses make longer journeys straightforward.

Best Time for Copenhagen Sightseeing

May through September is particularly convenient for extensive outdoor sightseeing because longer days make cycling, canal cruises, parks and waterfront exploration easier. Summer also brings Copenhagen's harbor spaces and outdoor food scene to life.

Winter offers a very different experience. Museums, palaces, bakeries and cafés become more important, while Christmas lights and seasonal Tivoli openings add atmosphere later in the year.

Regardless of season, bring layers and some protection against rain. Copenhagen's maritime weather can change quickly.

Final Thoughts

The best things to do in Copenhagen combine famous landmarks with experiences that reveal how the city actually functions. Tivoli Gardens provides historic entertainment, Rosenborg and Christiansborg tell Denmark's royal and political story, while Nyhavn and a canal cruise showcase Copenhagen's deep relationship with the water.

Yet the city's appeal extends beyond the major Copenhagen attractions. Cycling through residential neighborhoods, stopping at a bakery, walking beside the harbor and spending time in parks can be equally memorable.

For first-time travelers wondering what to do in Copenhagen Denmark, three or four days provides a comfortable introduction. Prioritize a few major sights rather than attempting everything, then leave enough time to wander. Copenhagen is compact enough for spontaneous exploration, and some of its most enjoyable moments occur between the headline attractions rather than inside them.
