First, buy a Copenhagen Card (USD70 for 48 hrs, Website), a discounted, hassle-free way to pay for public transport throughout the city, avail discounts at some hotels and entry to 74 museums and sights. The city centre is Indre By, where the famous shopping street, Strøget, has boutiques, cafés and tourist traps. The Danish parliament is also here, and you can walk in. The royal palace Amalienborg, which is guarded by the Danish Royal Lifeguards wearing big bearskin hats the beautiful Rosenborg Castle and its gardens, great for a picnic, are other highlights. The nearby Christianshavn borough has lovely canals, and the Vor Frelsers Kirke (Church of Our Saviour), with its tall and winding corkscrew spire. It's also home to Freetown Christania, an autonomous commune created by hippies in the 1970s, self-governed by its own Christiania Law of 1989. About 900 residents live in self-made houses, or on the streets, and run workshops and bars. It was controversial for allowing cannabis trade till 2004, but now the cops show up for raids from time to time. The area's run-down quality, while inspiring to some, was unappealing to others among my group. Local guides fear Indian tourists will try to buy cannabis, so will suggest you go there on your own. In the east, is peaceful water-facing family-friendly Øhsterbro, with broad boulevards, the Copenhagen lakes, the seafront Little Mermaid statue, and the Aamanns restaurant. Once a red-light district, Vesterbro is fashionable, modern and has a great nightlife. The Istedgade street has sex shops on one end and the cosy family Enghave Park on the other. There are second-hand stores, small cafés and bars selling special beers and old-school cocktails. The Carlsberg Museum is also here. Going north from Vesterbro, you technically leave Copenhagen,and reach Frederiksberg, the most expensive neighbourhood in the capital region. The Copenhagen Zoo, Frederiksberg Palace and the oldest gay bar in Copenhagen, Café Intime, are here.
