Quick answer: Four to five days is Copenhagen done properly: the classics and Tivoli’s evening glow, a bike-the-bridges day through Christianshavn and Reffen, the Louisiana art-museum coast day every visitor remembers — and a Malmö or castles finale across the water.
Day 1: Nyhavn & the royal core
Quay-side coffee before the crowds, Amalienborg’s noon guard change, Rosenborg’s crown jewels, smørrebrød at Torvehallerne — then Tivoli at dusk: lights, lake, closing fireworks in season.
Day 2: bike like a local
Rent wheels: the Cykelslangen ramp, Christianshavn’s canals, Freetown murals, harbour-bath swims (summer proof the water’s clean) and Reffen’s street-food hangars.
Day 3: the Louisiana day
Forty minutes north: the Louisiana Museum’s sculpture coast — art, sea and light in perfect proportion. Pair with Kronborg (Hamlet’s castle) at Helsingør for the full coast run.
Day 4: neighbourhoods & depth
Nørrebro’s Jægersborggade lane, assistens cemetery strolls (Andersen and Kierkegaard), Vesterbro’s meatpacking nights — the lived-in city beyond the postcards.
Day 5: Malmö or museums
Twenty-five minutes over the Øresund bridge to Sweden (passport!), or double down: the National Museum’s Vikings and the round-tower climb.
FAQ
Is the Copenhagen Card worth it? Doing 2+ paid sights daily plus transit — usually yes; bike-and-wander trips can skip it.
How expensive is Copenhagen? Nordic: dinners sting, lunches and street food behave — see our capital comparison.
Best months? May–September for harbour life; December for Tivoli’s Christmas.
Weekend version? Compress days 1–2 — our 2-day plan does exactly that.
