Top Free Things to Do in Copenhagen with Kids
Finding free activities in Copenhagen does not mean settling for less. Some of the most innovative and memorable spaces in the city cost absolutely nothing to enjoy.
Konditaget Lüders (The Rooftop Playground)
Copenhagen has a knack for turning utilitarian spaces into architectural wonders, and Konditaget Lüders is the perfect example. Located in the modern Nordhavn district, this vibrant, red-hued rooftop space sits atop an eight-story parking garage. Instead of a concrete roof, the city built an active urban playground featuring trampolines, climbing structures, swings, and a sprint track. Kids can burn off endless energy bouncing and climbing while parents take in the sweeping, panoramic views of the harbor and the Øresund Strait.
- Opening Hours: Daily, 7:00 AM to 10:00 PM.
- Cost: 100% Free.
- Stroller Accessibility: Excellent. There is a large, reliable elevator that takes you directly from the street level to the roof.
- Nearest Food: The ground floor of the parking structure houses a well-stocked Meny supermarket, perfect for grabbing fresh pastries, fruit, and juice for a rooftop snack.
- Best Time to Visit: Mid-morning. It tends to fill up with local teenagers and fitness enthusiasts in the late afternoon.
- How Long to Spend: 1 to 1.5 hours.
Kalvebod Bølge (The Harbor Wave)
Located along the waterfront, Kalvebod Bølge is a striking wooden promenade that undulates out over the harbor. It was designed to bring the city closer to the water, and for children, it feels like a giant, abstract climbing frame. The structure features varying levels, slopes, and hidden nooks. Older kids love running up the wooden waves and lounging on the cargo nets suspended over the water. During the summer, locals use the surrounding harbor baths for swimming. Parent warning: The water is right there, and there are no fences. You will need to keep a very close eye on toddlers and impulsive preschoolers.
- Opening Hours: 24/7.
- Cost: 100% Free.
- Stroller Accessibility: Good. The main promenade is accessible via ramps, though you will need to leave the stroller parked to climb the "waves."
- Nearest Food: The nearby Fisketorvet shopping mall has a massive food court with options ranging from sushi to traditional Danish open-faced sandwiches.
- Best Time to Visit: Late afternoon on a sunny day to watch the boats go by.
- How Long to Spend: 45 minutes to 1 hour.
Valbyparken (The Themed Gardens)
When your family needs a break from cobblestones and urban energy, head to Valbyparken, the largest park in Copenhagen. This sprawling green escape offers way more than just open grass. It features 17 distinct themed gardens, including a stunning circular rose garden, a water garden, and a tactile garden designed specifically to engage the senses. For children, the highlight is the massive natural playground, one of the largest in Denmark, featuring winding wooden towers, long slides, and water-play areas built seamlessly into the surrounding forest.
- Opening Hours: 24/7.
- Cost: 100% Free.
- Stroller Accessibility: Perfect. The park has wide, flat, paved, and hard-packed gravel paths throughout.
- Nearest Food: There is a small seasonal café in the park serving coffee and ice cream, but packing a picnic from a local bakery is the best approach.
- Best Time to Visit: Mid-day, especially when the kids need a long, unstructured run-around.
- How Long to Spend: 2 to 3 hours.
LEGO Store Copenhagen
While buying LEGO sets will certainly cost you, visiting the flagship LEGO Store Copenhagen on the Strøget pedestrian street is completely free and serves as a mini-museum of brick art. The store features massive, intricate models of Copenhagen landmarks, including a huge build of the Nyhavn canal and royal guards made entirely of LEGO bricks. Kids can spend time at the free building tables scattered throughout the store, creating their own masterpieces. It is a fantastic, zero-cost way to experience Denmark’s most famous export if you do not have the time or budget to travel out to the LEGO House (Billund).
- Opening Hours: Typically 10:00 AM to 6:00 PM (varies slightly by season and day of the week).
- Cost: Free to enter and play.
- Stroller Accessibility: Doable, but the store gets extremely crowded. A baby carrier is much easier to navigate here.
- Nearest Food: You are right on Strøget, surrounded by cafes, hot dog stands (pølsevogn), and bakeries.
- Best Time to Visit: Right at opening time (10:00 AM) to beat the heavy tourist crowds.
- How Long to Spend: 30 to 45 minutes.
The Driverless Metro and Havnebus (Transit Hacks)
While technically requiring a transit ticket (or the Copenhagen Card), kids under 12 ride public transit for free when accompanied by a paying adult, making these transit hacks highly cost-effective entertainment. The Copenhagen Metro is fully automated and driverless. If you head to the very front of the train, there is a large, clear window where kids can sit and pretend they are driving the train through the underground tunnels. It is a thrilling, free activity that makes getting from point A to point B incredibly fun.
Similarly, skip the expensive private canal tours and hop on the yellow Havnebus (Harbor Bus). It is part of the public transit system and zig-zags across the harbor, offering fantastic views of the Opera House, the Black Diamond library, and the city skyline for the price of a standard bus fare.
Worth the Splurge: Paid Things to Do in Copenhagen with Kids
While keeping costs low is great, a few experiences in Copenhagen are absolutely worth allocating budget toward. These world-class attractions provide immense value for families.
Experimentarium
Located in Hellerup (just north of the city center), the Experimentarium is a massive, world-class science center housed in a former brewery. Every single exhibit is designed to be touched, climbed, and manipulated. Highlights include the Bubble Solarium, where kids can stand inside giant soap bubbles, and the interactive Port area, which simulates global shipping logistics through massive ball-pit mechanics. It is, without a doubt, one of the best indoor activities in Scandinavia.
- Practical Details: Tickets are roughly 235 DKK ($34 USD) for adults and 145 DKK ($21 USD) for children. Plan to spend at least 4 hours here. There is a great, healthy cafeteria on-site.

Den Blå Planet (National Aquarium Denmark)
Northern Europe's largest aquarium, Den Blå Planet (National Aquarium Denmark), is a stunning architectural marvel shaped like a giant whirlpool. Inside, it puts you face-to-face with sea otters, hammerhead sharks, and an incredible Amazonian rainforest exhibit where butterflies and birds fly freely above the water. The outdoor water playground is a massive hit with younger kids during the warmer months.
- Practical Details: Tickets are roughly 210 DKK ($30 USD) for adults and 110 DKK ($16 USD) for kids. It is located near the airport, making it a great first or last stop on your itinerary.

Tivoli Gardens (Seasonal Events)
Tivoli is magical year-round, but it truly shines during its seasonal transformations. If you visit in autumn, the Tivoli Gardens Halloween Season brings over 20,000 pumpkins and elaborate, gently spooky decorations. In winter, the Tivoli Gardens Christmas Season turns the park into a fairy-light-draped winter wonderland with holiday markets and hot gløgg (mulled wine).
- Practical Details: Entrance alone is about 155 DKK ($22 USD), but ride passes are extra. Aim to arrive around 3:00 PM so you can experience the park in daylight and stay as the millions of lights turn on after dark.
What to Skip in Copenhagen with Kids
Protecting your budget also means avoiding attractions that overcharge and underdeliver. Skip these tourist traps and redirect your time toward authentic Danish experiences.
The Little Mermaid (Den Lille Havfrue)
It is the most famous landmark in Copenhagen, but The Little Mermaid (Den Lille Havfrue) is notoriously underwhelming for children. It is a surprisingly small statue located far from other major sites, requiring a long, often windy walk along the harbor. When you finally arrive, you are met with throngs of tour groups elbowing for photos. Kids are not allowed to climb or touch the statue. Save your walking energy for something interactive.
Generic Tourist Traps on Strøget
Avoid Ripley's Believe It or Not! Copenhagen and the Hans Christian Andersen Experience (Copenhagen). These are expensive, generic attractions that lack local Danish charm and feel incredibly dated. The Hans Christian Andersen walkthrough is essentially a series of dusty mannequins pushing buttons to hear stories. Your money is much better spent on a locally designed experience like the Experimentarium.
Stuffy Museums and Adult Dining
While Copenhagen is a culinary capital, ultra-fine dining spots like Noma are multi-hour, expensive marathons that are entirely unsuitable for children. Likewise, unless you have deeply historical older teens, skip the Amalienborg Museum. While the palace exterior is iconic (and the free changing of the guard is fun to watch at noon), the museum interior consists of static royal rooms roped off from the public, which will bore younger travelers to tears.
Age-By-Age Guide for Free Things to Do in Copenhagen with Kids
Tailoring your itinerary to your children's developmental stages ensures everyone stays happy and engaged.
- Toddlers (Ages 2-3): Focus on the wide-open spaces of Valbyparken where they can safely toddle without traffic worries. The sensory gardens are perfect for little hands to explore. Also, riding the Havnebus is a gentle, soothing way to see the city, and the rhythmic motion often results in a great stroller nap.
- Preschoolers (Ages 3-5): This age group thrives on imagination and physical play. The LEGO Store Copenhagen provides instant gratification with its free building stations. They will also be utterly obsessed with snagging the front seat of the driverless Metro, pretending they are steering the train through the tunnels.
- School-Age (Ages 6-10): Kids this age need larger physical challenges. The trampolines and sprint tracks at Konditaget Lüders are perfect for burning off mid-morning energy. They will also love navigating the wooden slopes of Kalvebod Bølge, treating it like an urban obstacle course.
- Tweens and Teens (Ages 11-14): Older kids appreciate independence and cool aesthetics. Let them lead the navigation through the modern architecture of the Nordhavn district. They will also appreciate the street-food culture at places like Reffen, where they can wander safely and choose their own eclectic meals from various shipping container stalls.
Pro Tips from Parents for Visiting Copenhagen
- Rent a Christiania Bike: Do as the locals do and rent a cargo bike (often called a Christiania bike). It is the most efficient and fun way to move multiple tired kids across the city. The kids sit in the wooden bucket up front, completely engaged with their surroundings, while you pedal (many are electric-assist now, making it a breeze).
- Time Your Meals at Reffen: The outdoor street food market, Reffen, is fantastic for families due to the massive variety of food. However, it becomes very crowded, loud, and geared toward young adults drinking after 6:00 PM. Arrive around 4:30 PM for an early dinner, grab a spot in the sand by the water, and head out before the evening rush.
- Skip Nyhavn Restaurants: Avoid the overpriced, tourist-heavy restaurants lining the iconic Nyhavn canal. Instead, grab a giant waffle cone at Vaffelbageren, sit on the edge of the canal (watching carefully, of course), and enjoy the view for a fraction of the cost.
- Try a Flødeboller: For a relatively cheap and highly authentic treat, stop by Summerbird Organic for a 'Flødeboller.' It is a chocolate-covered marshmallow treat on a marzipan base that is a beloved Danish childhood staple. It is messy, delicious, and a cultural experience in itself.
- Stroller Accessibility is Elite: Copenhagen is one of the most stroller-friendly cities on earth. Ramps, wide sidewalks, and spacious elevators in public transit stations are the norm. Do not hesitate to bring your full-size travel stroller; you will not have to lug it up endless flights of stairs like in Paris or London.
Copenhagen proves that you do not need an unlimited budget to create lasting family memories in Scandinavia. By leaning into the city’s incredible public infrastructure, world-class parks, and clever transit options, you can balance the budget while still experiencing the absolute best of Danish design and culture. Whether you are bouncing on a rooftop overlooking the harbor or steering a driverless train beneath the city streets, finding the best things to do in copenhagen with kids is an adventure in itself. Pack your comfortable walking shoes, embrace the local biking culture, and get ready to explore one of Europe's most family-centric capitals.
