Copenhagen (København — "merchants' harbour") is the happiest city in the world (World Happiness Report, regularly, as a proxy for the happiest country — Denmark) and the capital of the country that invented hygge (the Danish concept of cosy contentment — candlelight, good coffee, good company, and the rejection of excess). Denmark's capital (population 1.35 million) is also the gastronomic capital of northern Europe since Noma (René Redzepi's restaurant that invented New Nordic cuisine in 2003 and has been the world's #1 restaurant multiple times) transformed not just Copenhagen but the entire way the world thinks about local, seasonal, fermented and foraged food. The city itself — the Nyhavn harbour (the postcard row of coloured townhouses along the canal, the most photographed image in Scandinavia), Tivoli Gardens (the world's second-oldest amusement park, opened 1843, which inspired Walt Disney to build Disneyland), the Little Mermaid, Christiansborg Palace and the free commune of Christiania — is compact, cycle-friendly and extraordinarily beautiful.
Nyhavn (New Harbour — the 17th-century canal district of coloured merchant townhouses (red, yellow, green, blue), now the most photographed image in Scandinavia and the tourist heart of Copenhagen) is at its most beautiful at dawn before the outdoor café tables fill up: Hans Christian Andersen lived at no.20 (1835), no.67 (1867) and no.18 (1848) at different times — three plaques mark his residences in the street where he wrote some of his most famous fairy tales.
🎫 Book tickets via GetYourGuideChristiansborg Slot (the Palace on Slotsholmen island — the only building in the world that houses all three branches of government: the Parliament (Folketing), the Supreme Court and the Prime Minister's Office, plus the Royal Reception Rooms and the Royal Stables) is the political and historical heart of Denmark. The Palace Tower (106m — the tallest tower in Copenhagen, free, the finest 360° view of the city from the top) and the Royal Stables (white sand floor, Dutch-style stabling for 80 horses) are highlights.
🎫 Book tickets via GetYourGuideThe Nationalmuseet (Princes' Palace, free admission) has the finest pre-Roman Iron Age and Viking collection in the world: the Trundholm sun chariot (1400 BC — the most beautiful Bronze Age object ever found in Scandinavia, a horse pulling a gilded sun disc across the sky), the Hjortspring boat (320 BC — the oldest Nordic warship ever found, 19m long, built by bending green oak with no tools except stone and bone), and the Viking room with the original Jelling runic stones (copies — the originals are in Jutland).
🎫 Book tickets via GetYourGuideTivoli Gardens (Vesterbrogade 3, opened August 15, 1843 — the second-oldest amusement park in the world after Dyrehavsbakken north of Copenhagen, which Walt Disney visited in 1951 as the inspiration for Disneyland) is not just a funfair but a beautifully designed park of rides, restaurants, a concert hall (the finest outdoor venue in Copenhagen), lanterns and gardens. The Rutschebanen (1914, the oldest wooden roller coaster still in operation in the world) and the Demon are the rides. In summer (mid-April–September) and at Christmas (mid-November–January 2).
🎫 Book tickets via GetYourGuideCopenhagen has 390km of dedicated cycle paths and 63% of residents cycle to work every day (the highest rate of any city in the world). Renting a city bike (Donkey Republic or Baisikeli, DKK 99–129/day) and cycling from Nyhavn to Christiania to the Little Mermaid to the Design Museum is not only the fastest way to see the city — it IS the Copenhagen experience. The harbour cycling path along Havnegade gives the finest cycling view of Christianshavn.
🎫 Book tickets via GetYourGuideChristiania (the 34-hectare "free town" in Christianshavn, established in 1971 by squatters who occupied an abandoned military barracks and declared it an autonomous anarchist community, recognized but not fully legalized by the Danish state — population 900, its own flag and currency, its own rules (no hard drugs, no cars, no photographs on Pusher Street)) is one of the most extraordinary urban experiments in Europe: a functioning commune with its own art galleries, restaurants, live music venues and community governance, operating for 54 years.
🎫 Book tickets via GetYourGuideThe Designmuseum Danmark (Bredgade 68, in the former Royal Frederik's Hospital, 1757 — the finest design museum in Scandinavia: the permanent collection of Danish design from 18th-century porcelain to the Arne Jacobsen Egg chair (1958) and Swan chair (1958), the Hans J. Wegner Y-Chair (1949 — the most copied chair in history), the Bang & Olufsen audio systems and the annual design exhibitions that define Scandinavian design culture globally) is the best introduction to why Danish design is different from every other national design tradition.
🎫 Book tickets via GetYourGuideThe Little Mermaid (Den Lille Havfrue — 1913, sculptor Edvard Eriksen, the bronze mermaid of the Hans Christian Andersen fairy tale, the most photographed monument in Denmark despite being smaller than most visitors expect: 1.25m sitting on a rock at Langelinie) is the city's most iconic image. Walk from there to the Kastellet (the 17th-century star-shaped fortress still used by the Danish military — the pentagonal ramparts and water moat are among the best preserved Renaissance fortifications in northern Europe, free, beautiful for an evening walk).
Smørrebrød (open-faced rye bread sandwiches — the Danish lunch tradition that has been elevated to fine dining: slices of dense dark rye bread (rugbrød) topped with pickled herring (various preparations), smoked salmon, roast beef with remoulade, liver pâté, and the finest Danish cheeses — each topping arranged with the precision of Japanese sushi) at Restaurant Schønnemann (Hauser Plads 16, since 1877 — the oldest smørrebrød restaurant in Copenhagen, the definitive address) with a snaps of aquavit.
🎫 Book tickets via GetYourGuideRosenborg Slot (1624, King Christian IV — the Dutch Renaissance castle in the middle of Copenhagen, built as a summer residence and now a museum of the Danish monarchy: the Crown Jewels (in the actual treasury in the castle basement — the crown of Christian V, 1671, the orb, the sceptre and the Queen's jewellery collection), the Knight's Hall (with the three silver lions that guard the throne) and the personal rooms of Danish monarchs from 1606 to 1863 preserved intact).
🎫 Book tickets via GetYourGuideTorvehallerne (Israel Plads — opened 2011, the two covered glass market halls with the finest food stalls in Copenhagen: Paper Island Bao Bar, the Grød porridge counter, the Coffee Collective (the finest single-origin coffee roaster in Denmark), the fresh fish counter, the macaron stall and the hot dog stall (the pølsevogn — the Danish hot dog (røde pølse) in a brioche bun with fried onions, mustard, remoulade and ketchup — the original fast food of Copenhagen). The Saturday rush is extraordinary.
🎫 Book tickets via GetYourGuideCopenhagen Harbour Baths (Islands Brygge — the free outdoor sea swimming pools in the inner harbour, open June–August, water tested daily for purity. Notably, Copenhagen's inner harbour water is clean enough to swim in — a remarkable achievement for a city of 1.35 million that has done so through stringent pollution control over 30 years) or a kayak tour (Copenhagen City Kayaks, DKK 399 for 2 hrs, the most unusual way to see the Christianshavn canals and the Christiania waterfront).
