Most of Copenhagen's most popular attractions and sights are within walking distance. And the city has so much more to offer than the three most famous ones; Tivoli Gardens, the statue of The Little Mermaid, and the freetown of Christiania.
With a history that dates back to 1043, the city is full of historic landmarks, significant buildings and interesting sights and museums. For instance Christiansborg Palace and the picturesque Nyhavn.
Travel hack: Some attractions and museums do not allow luggage. LuggageHero and several other services help you store your bags, so you can use your day of departure exploring the city's attractions without dragging your luggage along.
