10 Best Sights in Copenhagen, Denmark

En route from Christianshavn to Refshaleøen is Copenhagen's legendary freetown Christiania, which was founded in 1971, when students occupied army barracks. It's now a peaceful community of nonconformists, consisting of 630 adults and 130 kids, where wall cartoons preach drugs and peace. There are a number of businesses here, including a bike shop, a smithy, a rock-music club, and several good organic eateries. When exploring Christiania, make sure to leave the central, busy part of the community to walk around on the idyllic, pedestrian paths that run through the forest, past the riding school, along the lake, and between the imaginative self-built houses.

A group of residents recount their experiences as well as the history of Christiania on daily English-language tours, which are a great way to discover the nooks and crannies of this quirky community.

Many inhabitants are not fond of cameras, and picture taking is forbidden on Pusher Street.

One of the best museums of its kind in Europe, the National Museum sits inside an 18th-century royal residence that's peaked by massive overhead windows. Extensive permanent exhibits chronicle Danish cultural history from prehistoric to modern times. The museum has one of the largest collections of Stone Age tools in the world, as well as Egyptian, Greek, and Roman antiquities. The exhibit on Danish prehistory features a great section on Viking times. The children's museum, with replicas of period clothing and a scalable copy of a real Viking ship, makes history fun for those under 12. Displays have English labels, and the do-it-yourself walking tour "History of Denmark in 60 Minutes" offers a good introduction to Denmark; the guide is free at the information desk.

Old Master paintings—including works by Rubens, Rembrandt, Titian, El Greco, and Fragonard—as well as a comprehensive array of antique and 20th-century Danish art make up the National Art Gallery collection, the biggest art museum in Denmark. Also notable is the modern art, which includes pieces by Henri Matisse, Edvard Munch, Henri Laurens, Emil Nolde, and Georges Braque. The space also contains a children's museum, which puts on shows for different age groups at kids' eye level. Wall texts are in English. The bookstore and café, which was recently taken over by Frederik Bille Brahe, one of Copenhagen's most hyped chefs, are also worth a visit.

Tivoli is not only Copenhagen's best-known attraction, but also the most charming one. The amusement park, the second-oldest in the world, is located conveniently next to the city's main train station and attracts an astounding 4.4 million people from mid-April to mid-September. Tivoli is a pleasure garden as well as an amusement park. Among its attractions are a pantomime theater, an open-air stage, several dozen restaurants (some of them very elegant and with Michelin stars), and frequent concerts—from classical to rock to jazz. Fantastic flower exhibits color the lush gardens and float on the swan-filled ponds. The park was established in the 1840s, when Danish architect George Carstensen persuaded a worried King Christian VIII to let him build an amusement park on the edge of the city's fortifications, rationalizing that "when people amuse themselves, they forget politics." Try to see Tivoli at least once by night, when 100,000 colored lanterns illuminate the Chinese pagoda and the main fountain. Tivoli is also open select hours around Halloween and in the winter season.

This museum chronicles the working class from 1870 to the present, with evocative life-size "day in the life of" exhibits, among them reconstructions of a city street and re-creations of apartments, including the home of a brewery worker, his wife, and eight children. Changing exhibits focusing on Danish and international social issues are often excellent. The exhibitions have explanatory texts in English. The museum also has a 19th-century-style café and beer hall serving old-fashioned Danish specialties and a 1950s-style coffee shop.

Trees, flowers, ponds, sculptures, and a spectacular 19th-century Palmehuset (Palm House) of tropical and subtropical plants blanket the garden's 25-plus acres. There's also an observatory and a geological museum. Take time to explore the gardens and watch the pensioners feed the birds. Some have been coming here so long that the birds actually land on their fingers.

This small statue from 1913 commemorates Hans Christian Andersen's lovelorn Little Mermaid. You may want to read the original Hans Christian Andersen tale in advance; it's a heartrending story that's a far cry from the Disney animated movie. Donated to the city by Carl Jacobsen, the son of the founder of the Carlsberg Brewery, the innocent waif has also been the subject of some cruel practical jokes, including decapitation and the loss of an arm, but she's currently in one piece. The Langelinie Promenade is thronged with Danes and visitors making their pilgrimage to the statue, especially on sunny Sundays. Although the statue itself is modest, the views of the surrounding harbor are not.

Situated at the western end of the lakes that divide Copenhagen, this modern, cylindrical planetarium appears to be sliced at an angle. It's Denmark's most advanced center for popularizing astronomy and space research and promoting knowledge of natural science. The on-site IMAX Theater is devoted to visual odysseys of the natural environment—below the sea, through the jungle, or into outer space. These films aren't recommended for children under age seven.

This Renaissance structure—built by King Christian IV and one of central Copenhagen's oldest—contains impressive displays of uniforms, weapons, and armor in a 600-foot-long arched hall. Children usually like this museum, but it's very much a look-but-don't-touch place. Each artifact has a label in English.

Established in 1859, the Copenhagen Zoo blends the old with the new. The elephant house, by acclaimed architect Norman Foster, is an elegant structure topped by two glass domes, providing its inhabitants with plenty of light and stomping ground. Modern glass enclosures for hippos and polar bears also make for spectacular viewing. But children are just as likely to gravitate to the small petting zoo and playground, which includes friendly cows, horses, rabbits, goats, and hens. The indoor rain forest has butterflies, sloths, alligators, and other tropical creatures. On sunny weekends, the line to enter can be long, so come early.

There are often extended weekend and summer opening hours
