3 days in Copenhagen: itinerary

Three days is enough for Copenhagen if you treat the city as one compact unit and give one of the three days to a day trip. The centre — Indre By, Nyhavn and the harbour — is walkable end to end in about 40 minutes, and the metro plus a rented bike covers everything else.

If you have only three days, do not try to see Zealand as well. Pick one out-of-town target: Kronborg at Helsingør, the Viking ships and cathedral at Roskilde, or Malmö over the Øresund bridge. Trying two of them leaves the city itself half-seen.

Book Tivoli, any castle you plan to enter, and long-distance trains before you arrive in summer and December. Copenhagen hotels fill on summer weekends and during the Christmas season.

Copenhagen's sights cluster tightly. Indre By holds the Round Tower, Strøget, Christiansborg and the National Museum within a 15-minute walk of each other. Nyhavn and the harbour sit just east; the Little Mermaid statue is a further 20–25 minutes north along the water, or one stop on the harbour bus.

Vesterbro is the area around the central station and Kødbyen's meatpacking district, 10–15 minutes on foot from the station. Nørrebro is 10 minutes by metro or 20 by bike from the centre. Amager and the beach at Amager Strand are 15 minutes by metro.

For day trips, trains leave Copenhagen central station for Helsingør (about 45 minutes), Roskilde (about 25 minutes) and Malmö (about 35 minutes across the Øresund). All three run frequently through the day.

Copenhagen is flat and bike-first. Renting a bike is often faster than the metro for short hops, but the cycle lanes are busy at rush hour and you need lights after dark. If you would rather not cycle, the metro, S-tog and harbour bus cover the city well; a rechargeable travel card or the DOT app handles all of them.

Money: Denmark uses the krone (DKK) and cards are accepted almost everywhere, including small kiosks. You rarely need cash. Tipping is not expected; service is included.

Food and drink are the biggest cost. Lunch at a food hall or a bakery (smørrebrød, pastries) is far cheaper than a sit-down dinner. Supermarkets and 7-Eleven are everywhere for picnic supplies.

Weather: mild, damp and windy year-round. Summer highs are 20–24 °C with up to 17 hours of light; winter is 0–4 °C with about 7 hours. Pack a rain layer whatever the month.

Closures: shops shut on 24–26 December and on the Easter holy days; many restaurants close 24–25 December and 1 January. In July some city restaurants take their own holiday. Check opening days around public holidays.

If you are short on time, a city pass can pay off only if you plan several paid museums in one day — run the numbers against your own list before buying.

Copenhagen Airport (CPH) at Kastrup is 15 minutes from the centre by metro (M2) or about 12 minutes by train to the central station. Both run frequently from early morning to late night; a taxi takes 20–30 minutes depending on traffic.

From the UK, Ireland and most of Europe, direct flights land at CPH in 1.5–3 hours. From the US, expect one stop via a European hub, or a direct flight from a few East Coast cities in season. From Australia and New Zealand, one or two stops is normal.

By train, Copenhagen connects to Malmö and the rest of Sweden over the Øresund bridge, and to Hamburg and the continent via the Danish network. Overnight and long-distance services book up in summer and around holidays.

Once in the city, the metro, S-tog, buses and harbour bus share one ticketing system. Buy single tickets or a rechargeable card, or use the DOT app. Contactless bank cards work on some readers (check).
