COPENHAGEN · A PARENT-TESTED GUIDE

10 unmissable things to do in Copenhagen with kids

A genuinely useful family guide to the experiences children will enjoy—with honest advice on timing, food, saving money and what you can safely skip.

Copenhagen is one of those cities that works remarkably well with children. It is compact, easy to navigate and full of experiences that feel exciting without every day becoming an exhausting military operation.

This is not a list of famous landmarks included simply because every Copenhagen guide mentions them. These are ten experiences children can genuinely enjoy, with practical tips from actually visiting the city as a family.

Before you leave the hotel

Wear comfortable shoes and take a lightweight backpack. Copenhagen is wonderfully walkable, but a family sightseeing day can involve far more steps than expected.

If you are visiting in summer, pack refillable water bottles. Use the backpack for water, picnic food, a light layer, pencils and a few activity pages—but keep it light enough that carrying it does not become another problem.

Copenhagen is overwhelmingly card-friendly. Contactless payment is normally the easiest option for attractions, cafés, transport and food stands. Take a second payment method as a backup and check whether your bank charges foreign-transaction fees.

1. Explore Den Blå Planet—then go crabbing

Den Blå Planet, Denmark's national aquarium, deserves a substantial part of the day rather than a hurried visit between other attractions.

Book the earliest morning entry slot if possible. You will arrive before the aquarium becomes too crowded, giving children more space and time to enjoy the exhibits.

Do not automatically leave when everyone becomes hungry. The café is excellent and can be better value than eating in central Copenhagen. It also gives the family a proper break without sacrificing another hour travelling somewhere else for lunch.

Before leaving, make sure you try the free crabbing activity outside. It is simple, wonderfully Danish and may become one of the experiences children remember most.

Parent tip: Reserve an early slot, plan to eat at the aquarium and leave enough time for crabbing afterwards.

2. Experience Tivoli without exhausting everyone

Tivoli Gardens is magical, but timing makes an enormous difference. Arrive early while the gardens and rides are quieter, or go later in the afternoon as some daytime visitors begin to leave and the lights start coming on.

Do not feel that you have to race from ride to ride to justify the ticket price. Find one of the cafés, order a beer and a lemonade, and let everyone have a proper break. Tivoli is as much about enjoying the atmosphere as it is about completing every attraction.

If you can, finish with dinner at Tivoli Food Hall. Everyone can choose something different, it is easier with children than a formal restaurant, and it creates a relaxed ending to the visit.

Parent tip: Avoid arriving during the busiest middle part of the day. Early means shorter queues; later afternoon brings more atmosphere.

3. See Copenhagen from the water

Copenhagen makes more sense when you see it from the harbour. A canal tour gives tired feet a rest while children watch bridges, colourful houses and boats pass close by.

For a cheaper, more local alternative, use one of the yellow harbour buses. It is public transport rather than a narrated tour, but that is part of the fun. You still see the city from the water and can hop off when something catches your attention.

Children who are normally impatient with conventional sightseeing often enjoy the simple movement of the boat, going beneath bridges and spotting different vessels along the route.

Parent tip: Keep a light layer in the backpack. The breeze on the water can feel considerably cooler than the streets, even in summer.

4. Eat a proper Danish hot dog

One of the easiest Copenhagen meals with children is also one of the most enjoyable. Find a traditional pølsevogn, order a Danish hot dog and eat it standing outside like a local.

The classic version can arrive with mustard, ketchup, remoulade, raw and crispy onions and pickles. Children who prefer simpler food can normally ask for fewer toppings.

It is quick, relatively inexpensive and much more memorable than retreating into another international fast-food restaurant. It also works perfectly between attractions when nobody wants to lose an hour over lunch.

Parent tip: Order one fully loaded version for the adults and a simpler one for cautious children.

5. Buy a picnic and slow down in the King's Garden

Not every Copenhagen memory needs an entrance ticket. Buy bread, fruit, pastries, drinks and a few Danish treats from a supermarket or bakery, then take everything to the King's Garden beside Rosenborg Castle.

It is considerably cheaper than taking the whole family to another city-centre restaurant. You get to eat outside, and children have room to move around rather than sit through another formal meal.

Bring a small ball, pencils or a few pages from the Copenhagen activity pack and allow this to become the slower part of the day. Parents get a breather, children get some freedom and the holiday budget gets a welcome break.

Parent tip: A supermarket picnic saves money without making the day feel like a compromise.

6. Let children experiment at Experimentarium

Experimentarium is the place for children who want to touch, test and try everything rather than walk quietly past display cases.

The hands-on science exhibits offer a useful change of pace after palaces and historic streets. It is also an excellent wet-weather option, although it can easily occupy several hours, so avoid squeezing it into an already full afternoon.

The best approach is to let children lead. They will usually find the areas that interest them most, and the visit becomes far more enjoyable when adults resist the urge to complete every exhibit in order.

Parent tip: Treat Experimentarium as a major activity and check current opening arrangements before travelling.

7. Climb the Round Tower

The Round Tower gives families a view across Copenhagen without an endless staircase. Much of the ascent follows a broad spiral ramp, which makes the climb feel like part of the attraction.

Children can look for rooftops, church towers and the busy streets below once they reach the top. The climb is manageable for most families, but take your time and keep younger children close near the viewing areas.

Parent tip: Go when the weather is clear enough to enjoy the view. There is little point climbing purely to inspect a cloud.

8. Visit the Children's Museum at the National Museum

The National Museum can sound like a worthy adult choice that children must tolerate. Its Children's Museum changes that equation with spaces designed for play, imagination and hands-on discovery.

This is a good choice when the weather turns or when the family needs something more contained than another long walk. Check the current programme before visiting because activities and opening arrangements can change.

Parent tip: Do not attempt to cover the entire National Museum. Prioritise the child-focused areas and finish while everyone is still enjoying themselves.

9. Walk through Nyhavn—but do not eat there automatically

Nyhavn is busy and undeniably touristy, but the colourful houses, old boats and lively waterfront are still worth seeing. Children can look for boat names, count colours and choose the house they would most like to live in.

Walk through, take photographs and enjoy the atmosphere—but do not assume you need to sit down at the first waterfront restaurant. Prices reflect the location, and better-value family meals can be found away from the most obvious stretch.

Nyhavn works particularly well when combined with a boat trip rather than treated as a major half-day attraction in its own right.

Parent tip: Enjoy the view, then move a street or two away before deciding where to eat.

10. Choose Copenhagen Zoo for an easy family day

Copenhagen Zoo is a dependable choice when children need a day built around animals rather than architecture. It offers enough to fill several hours and sits beside Frederiksberg Gardens, so families can combine the zoo with more outdoor space.

Do not try to see every enclosure at speed. Choose the animals your children care about most, include proper breaks and leave while everyone still has some energy.

If your family already visits many zoos, you may prefer another uniquely Copenhagen experience. For animal-loving children, however, it is likely to be a highlight.

Parent tip: Check the day's programme when you arrive, then build a loose route around one or two events rather than constantly crossing the zoo.

Is the Little Mermaid worth visiting?

Honestly, not as a special journey with children.

The statue is much smaller than many visitors expect, the area can be crowded and there are far more enjoyable family experiences in Copenhagen. If you are already walking nearby, or your child knows the story and particularly wants to see it, stop for a quick look. Otherwise, do not feel guilty about missing it.

Your children are more likely to remember catching a crab, riding beneath a bridge, eating a hot dog or seeing Tivoli light up than standing behind a crowd to photograph a small statue.

The best Copenhagen days leave some space

The temptation on a city break is to fill every hour because there is so much to see. With children, Copenhagen is better when you choose one major experience, add one smaller activity and leave room for a park, a hot dog or something unexpected.

Go early when timing matters. Sit down when everybody needs a break. Carry water, wear comfortable shoes and do not mistake an expensive day for a successful one.

The aim is not to complete Copenhagen. It is to come home with a few family stories that everyone actually wants to remember.
