Christiania is not to be missed. The freetown was established in 1971 when squatters moved into an abandoned military area to create their own utopia. Today the Christiania community still exists as a pocket of informality in an otherwise very organized and well planned city. Especially the area behind the (in)famous Pusherstreet is worth a visit, as there are some wonderful examples of alternative and very imaginative architecture.

The Copenhagen Harbour Baths were once an industrial and polluted harbour area, but after several years of concentrated efforts to improve the water quality, Copenhagen’s inner harbour is now swimmable. There are two harbour baths, one is at Islands Brygge and the other, Copencabana, is close to the Fisketorvet shopping mall. The pools are among the most popular places in town to hang out on warm summer days and the season begins the first week of June and runs through the first week of September.

Tivoli is Copenhagen’s biggest tourist attraction with its more than 4 million annual visitors. This amusement park adjacent to the townhall square dates back to 1843 and still retains some of its faded elegance. Tivoli is especially worth a visit at night, when its 120,000 colored lamps illuminate the amusement park’s numerous attractions.   

Amalienborg Palace is the home of Denmark’s royal family and one of Europe's finest rococo palaces. It consists of four almost identical palaces, which surround an octagonal square, at the center of which stands the statue of a horse and rider. From Amalienborg there are spectacular views of the great dome of the Frederik's Church and across the harbour to the controversial new Copenhagen Opera House. 

The Little Mermaid is Copenhagen’s single most famous monument. Not surprisingly she sits in the seaspray at Langelinie close to the royal palace. Soon, however, she travels to Shanghai for the EXPO 2010, to be part of the Danish pavilion designed by local architects BIG.

The Royal Library also known as the ‘Black Diamond’, also sits on the waterfront and is a superb example of contemporary Danish architecture. The glass, steel and black granite façade is relieved by an atrium designed as an organic room in motion, which cuts into the structure with wave-lake balconies. The library is a very lively place as it hosts concerts and exhibitions, and its reading rooms are extremely popular among Copenhagen's students. The Black Diamond also boasts a restaurant and café where one can relax right on the waterfront and watch harbor life sail by.

The Canal Tours are a wonderful, and quite comfortable, way to see the Copenhagen from the water. The boats take you through the old and new districts of the city.

The Royal Danish Ballet is renowned among connoisseurs for its strong Bournonville tradition, which is characterised by the use of mimic and acting. Artistic director from 1830-77 (the golden age of Danish romanticism), August Bournonville choreographed more than 50 ballets, many of which still form the core of The Royal Danish Ballet’s repertoire.

The Lakes lay between the inner city districts of Nørrebro, Vesterbro, Østerbro and Frederiksberg and have served Copenhagen as both moats and water reservoirs. They are a brilliant location for people watching as they are one of the most popular hangout spots for Copenhageners. They also make the perfect starting point for explorations of Copenhagen's different neighbourhoods.
