Copenhagen's harbour was an industrial waterway until the late 1990s, closed to swimming and not somewhere you would put your hand. The city spent two decades separating its stormwater from its sewage and building treatment capacity, and by 2002 the water in the middle of the city was clean enough to open a public swimming facility in it.
There are now several harbour baths, free, unstaffed for much of the year, in the centre of a European capital. On a warm July evening several thousand people are in the water between office buildings. It is the single most impressive thing about the city and it costs nothing.
Why proximity to the water changes the trip
The baths are used casually, the way a park is used. People swim before work, at lunch, after work, and the season runs longer than visitors expect because a substantial number of Danes swim year round.
That only works if you are close. The main baths are at Islands Brygge, on the Amager side facing the centre, at Sandkaj in the newer Nordhavn district, and at Kalvebod Bølge on the western quay. If your hotel is a fifteen-minute walk from one of them, you will use it repeatedly. If it is a metro ride, you will go once with a towel and a plan.
The city is also small and flat, which means the harbour, Nyhavn, the Tivoli gardens and the royal palaces sit within about two kilometres of each other, and a bike covers all of it.
The ten below are grouped by which stretch of water they sit nearest.
The inner harbour and Nyhavn
The old waterfront, closest to Islands Brygge across the water and to the centre on foot.
Admiral Hotel Copenhagen occupies a converted 1787 granary on the waterfront with vaulted brick ceilings, oak beams and rooms that are genuinely unlike anything else in the city. It is a short walk to the Opera ferry and to Nyhavn.

What we have left off
The airport hotels at Kastrup are excluded, and they are convenient, comfortable and well priced. They are also eight minutes by metro from a city that is best experienced by walking out of the door into it.
What to do
Swim, if the weather allows. The baths are free, the water is tested continuously and there are lifeguards in high season.
Rent a bike on the first morning. Copenhagen has more bicycles than cars and the infrastructure is genuinely separated. Cycle to Refshaleøen for the street food halls and the former shipyard.
Do one castle, one museum, one garden. Rosenborg for the crown jewels, the Design Museum or the Glyptotek, and either Tivoli or the Botanical Garden.
Eat. Copenhagen changed European cooking twice over and the mid-priced restaurants are better than most cities' expensive ones. Book anything with a reputation months ahead.
Take the train to Louisiana, the modern art museum on the coast north of the city, which is 35 minutes each way and one of the best museums in Europe.
Practical notes
The airport is eight minutes by metro to the centre, which is the fastest airport link in Europe.
June to August is warm, long-daylight and the swimming season. May and September are pleasant and much cheaper. November to February is dark, cold and expensive to fly to but the city handles it well.
Copenhagen is very expensive. Cards are accepted everywhere and cash has effectively disappeared.

Questions people actually ask
Is the harbour water actually clean?
Yes, and it is monitored continuously with the baths closing if readings fall. This has been true for over twenty years.
When can you swim?
The baths run through the summer with lifeguards and stay open in shoulder season. Danes swim year round; visitors mostly do not.
Is Copenhagen worth the cost?
For food, design and the way the city works, yes. It is among the most expensive capitals in Europe and it is not pretending otherwise.
How many nights?
Three, four with a day at Louisiana or a trip across to Malmö, which is 35 minutes by train.
