Copenhagen in a Day: How to See the City on an Extreme Day Trip

Copenhagen is one of those rare cities that works beautifully for an extreme day trip. I’ve done it myself, and what surprised me most was how easy everything felt. The airport is close to the centre, the metro is fast, and the main sights sit within a compact, walkable area. Even if you’re starting the day in Billund, Malmö, Hamburg or stepping off a cruise ship with only a few hours to spare, you can still see a generous slice of the city. Colourful harbours, royal palaces, cosy cafés and a few classic viewpoints all fit comfortably into a single day, without it feeling rushed or chaotic. This guide keeps things simple and realistic, showing you exactly how to make the most of Copenhagen when time is tight.

Best flights to Copenhagen, Denmark

Copenhagen Airport (CPH) is the closest and only sensible option for a day trip. It’s well‑connected, efficient and linked directly to the city by metro and train. If you’re flying in from the UK, there are regular direct flights from London, Manchester, Edinburgh and several regional airports, and prices can be surprisingly reasonable outside school holidays. Travellers coming from elsewhere in Denmark, southern Sweden, or northern Germany often find that Copenhagen is the cheapest major hub in the region, with plenty of low‑cost and legacy airlines competing on the route.

How to get from Copenhagen Airport to the city centre

The airport sits just a few minutes from town, and both the metro and train run directly from Terminal 3.

By train – The train runs directly from Terminal 3 to Copenhagen Central Station and is one of the quickest ways into the city. The journey takes around 15 minutes, and trains run frequently throughout the day. Tickets are easy to buy from the machines in the arrivals hall, although booking in advance will always save you time. It’s a simple, reliable option if you’re heading towards Tivoli, the Meatpacking District or anywhere near the main station.

By metro – The metro runs straight from Terminal 3 into the city, with trains every few minutes and a journey time of around 15 minutes. It’s the easiest option for Nyhavn, Kongens Nytorv and Nørreport, and you can buy tickets from the machines in arrivals. There’s no need to book ahead, and the metro runs late into the evening, making it a simple choice for both arriving and heading back to the airport.

By taxi – This is the quickest but priciest option, with fares usually around DKK 250–350 into the centre. Official taxis wait just outside Terminal 3, and almost all accept card payments. There’s no need to agree a fare in advance as everything runs on the meter, but you can ask for an estimate before you set off. It’s the most convenient choice if you’re short on time, and you can easily hail a cab or ask your hotel to call one for the return journey.

By bus – Several local buses run from the airport into the city, but they’re generally slower than the metro or train. The most useful is the 5C, which goes to Copenhagen Central Station and Nørreport, taking around 30–35 minutes depending on traffic. Tickets are the same as the metro and train and can be bought from the machines in arrivals. It’s a straightforward option if you’re heading somewhere along the bus route, but not the quickest choice on a tight schedule.

Our One-Day Extreme Trip Itinerary

How much you fit into one day could certainly depend on how many hours you manage to have in between your flights. The following are all easily walkable, and where tickets are required, it is a good idea to prebook to avoid disappointment. You can amend this itinerary to suit your own day trip. Check open days and times before visiting and finalising your day.

Start your day – Where you arrive in Copenhagen will depend on what transport options you have taken into the city (see above). Our route below starts at a centrally located attraction, and it is mostly a walking route. Copenhagen is very compact and doable on foot. I have included below the only time it is worth taking public transport. You could book the 24-hour hop on hop off city sightseeing bus, which is great for getting around the main sites.

Nyhavn (Start Here -Walk)

Nyhavn is the perfect place to start a day in Copenhagen. It’s the city’s most recognisable harbour, a row of colourful 17th‑century townhouses, old wooden boats and cosy cafés lining the water. Even if you’ve only got a few hours in the city, it gives you that instant “this is Copenhagen” feeling. The cafes fill up fast, which is why this is another good reason to visit as soon as you can.
How to get here: If you’re already in the centre, it’s an easy walk from most places, or just hop on the metro to Kongens Nytorv and stroll the last couple of minutes. It’s a great spot for a quick coffee, a gentle wander along the canal and a few photos before you head off to explore the rest of the city. FREE to visit.

Amalienborg Palace (Walk – 10 minutes)

From Nyhavn, stroll along the waterfront to Amalienborg, home of the Danish royal family. The square is beautiful, and you can see the guards changing throughout the day. This happens every day at noon, so depending on when you visit, you may want to adjust this itinerary to coincide. There is a small but interesting museum you can visit. It’s inside Christian VIII’s Palace and gives you a look at royal life behind the scenes.
How to get here: Walk along the harbour path, it’s flat, scenic and quick. FREE to see from the outside. We visited during the changing of the guard, which is great to watch. There is a small charge to visit the museum.

The Little Mermaid (Metro plus Walk OR Walk Entirely)

This is the iconic spot in Copenhagen that’s slightly further out, so the metro helps if you’re short on time. I’ve always wanted to see it, but I was surprised by how small it is!
How to get here: Option A: Metro (fastest). From Kongens Nytorv, take the M3 or M4 to Østerport and then walk for around 10 minutes to the statue. Option B: Walk (if you prefer a scenic route). It’s about 25–30 minutes from Amalienborg along the waterfront. FREE to visit.

Rosenborg Castle & The King’s Garden (Walk – 15 minutes)

Head back towards the centre and stop at Rosenborg Castle, set inside the King’s Garden. Even if you don’t go inside, the grounds are lovely and very Copenhagen.
How to get here: Walk from Kastellet through Østerport and down to the gardens. FREE to walk around the gardens. It’s well worth a look inside, and we loved exploring it. Just note there’s an admission charge.

Torvehallerne Food Market (Walk – 5 minutes)

This is the perfect lunch stop; smørrebrød, pastries, coffee, open sandwiches, everything. It’s lively but not chaotic.
How to get here: Walk from Rosenborg, it’s just across the road at Nørreport.

Strøget & The Old Town (Walk – 5 minutes)

After lunch, wander through the pedestrian streets of Strøget, dipping into side streets, squares and cafés. This is the heart of the city and great for a wander.
How to get here: Walk directly from Torvehallerne. FREE to wander

Christiansborg Palace (Walk – 10 minutes)

Continue down Strøget until you reach Christiansborg, home to the Danish parliament. The tower is free and gives you a great view if the queue is short. With a ticket to Christiansborg Palace, you can visit the Royal Reception Rooms, the stables and the ruins beneath the palace, giving you a glimpse into both modern royal life and Copenhagen’s medieval foundations. It’s a compact set of attractions, easy to explore in an hour or two.
How to get here: Walk straight down the pedestrian street. As mentioned above, the tower is free. If you want to visit the Palace, tickets will need to be purchased in advance. There is a lot to see here, and it’s well worth the entrance fee.

Tivoli Gardens (Walk – 10 minutes)

Finish your day at Tivoli, especially if you’re visiting in winter or the Christmas season. Tivoli usually stays open later than most other attractions in Copenhagen, making it a great place to end your day. Opened in 1843, it’s one of the world’s oldest amusement parks, known for its beautiful gardens, nostalgic charm and brilliant mix of classic and modern rides.
How to get here: Walk from Christiansborg to Copenhagen Central Station, and Tivoli is right opposite. There is an entrance fee into Tivoli, and it costs extra to that to go on the rides. Tivoi is a great place to visit on an extreme day trip over Christmas.

Highlights of the day: Nyhavn pretty harbour – Amalienborg Palace (with a chance to see the changing of the guard) – Little Mermaid statue – Rosenborg Castle – Food market – The Old Town – Christiansborg Palace – Tivoli Gardens

A few more fun things to do in Copenhagen

Guinness World Records Museum: A light, silly, family‑friendly stop right off Strøget. Full of record‑breaking oddities, interactive bits and photo ops. Great if you want something easy and indoors.

Ripley’s Believe It or Not!: Right next door to the Guinness museum. My son loved this place! There are weird artefacts, illusions, curiosities and all the classic Ripley’s oddness. Very fun if you’re travelling with kids or just want a break from “serious” sightseeing.

The Round Tower (Rundetaarn): A gentle spiral walk to the top with lovely views over the rooftops. No stairs, just a sloping ramp. It’s right in the centre, so it’s an easy add‑on. Entry tickets are sold directly at the Round Tower’s ticket office.

Freetown Christiania: A unique, alternative neighbourhood with colourful murals, cafés and a very different vibe from the rest of the city. Best visited in daylight.

Canal Tour from Nyhavn: A classic for a reason; you see so much of the city in an hour, and it’s a great break for your feet. A boat tour is often included with the Copenhagen card.

Costs Breakdown

We paid £58 return per person for our extreme day trip to Copenhagen. I have seen flights around this price for a return via the links above. A lot of our itinerary includes free things to do. We paid to go inside Rosenborg Castle, Christiansborg Palace and Tivoli gardens, which cost £50 per adult (children are cheaper). All in, you could be between £60-110 per adult.

To save money on entrance to attractions, it may be worth purchasing the Copenhagen Discover card, which includes most public transport.

Top Tips for visiting Copenhagen

For a one‑day trip to Copenhagen, the best thing you can do is start early and keep things simple. The city is compact and incredibly walkable, so you’ll naturally see a lot just by wandering between the main sights. Use the metro for any longer hops, especially getting to Østerport for the Little Mermaid and stick to one area at a time so you’re not zig‑zagging across the city. Copenhagen is almost entirely cashless, so paying by card everywhere keeps things quick and easy.

If you want to add it to your day, a canal tour is a great way to see more of the city, as well as a city sightseeing bus. Keep an eye on bike lanes, as they’re busy and fast, and remember that many museums close around 5 pm, so plan indoor sights earlier in the day. If you’re visiting Tivoli, book ahead so you can head straight in without queuing.

In Conclusion

An extreme day trip to Copenhagen is full‑on but completely doable, and you’ll be amazed by how much you can see in such a short time. With its compact centre, effortless transport and beautiful waterfront streets, the city rewards every minute you spend exploring. Whether you’re wandering through Nyhavn, catching the Changing of the Guard, or squeezing in some theme park rides before heading home, Copenhagen delivers a day that feels rich, memorable and surprisingly relaxed for such a fast-paced itinerary.
