What should I avoid in Copenhagen?

Give Nyhavn 20 minutes and no money. The painted townhouses on the 1670s canal look exactly like the postcards, and the restaurants beneath them charge around DKK 90 for a draft Tuborg and close to DKK 200 for a plate of smørrebrød that costs half that elsewhere. Walk 20 minutes to Torvehallerne, the glass food halls by Nørreport station, where the rye-bread open sandwiches come piled with pickled herring and cold, grassy dill. The Little Mermaid disappoints more. Edvard Eriksen's 1913 bronze is about 1.25 metres tall and sits on a rock off Langelinie, and between 10am and 3pm the cruise coaches unload beside her in waves of 40. At 8am you might have her to yourself, with gulls shrieking over the harbour and the wind off the Øresund stinging your face, but if that hour doesn't suit you, skip her. Spend the time at Kastellet, the star-shaped fortress a few hundred metres south, where walking the grass ramparts is free.

Christiania is where first-timers get into real trouble. Signs at the gate of the Christianshavn commune ask visitors not to take photos, and that rule mattered most on Pusher Street, where hash was sold openly for decades. After shootings there in 2023, residents dug up the Pusher Street cobbles in April 2024 to drive the dealers out, and the strip still seems to be under rebuilding. Cannabis sold there was always illegal under Danish law, and police raids still happen. Visit in daylight, walk the lakeside paths, eat at Morgenstedet, the vegetarian cafe, keep your phone in your pocket near the old market strip, and buy nothing. Strøget is the other place to keep moving. The 1.1-kilometre pedestrian street from Rådhuspladsen to Kongens Nytorv is lined with the same H&M and Zara stores you have at home, and pickpockets work the crowds there and around Københavns Hovedbanegård, the central station. Copenhagen scores 7.8/10 for solo-traveler safety (see the TTDI Solo-Safety Index), and the main risk on Strøget is a lifted wallet, not violence.

The mistake nearly every first-timer makes in their opening hour in Copenhagen is stepping into a bike lane. The cycle tracks run between the pavement and the road, raised a curb's height, and riders come through at around 20 km/h with a sharp ring of the bell and little patience. Wait on the pavement side, look left twice, and when you get off a bus on Nørre Voldgade, never step straight into the lane. Transit has a trap of its own. From Kastrup airport the M2 Metro reaches Kongens Nytorv in about 15 minutes, and because there are no ticket gates, visitors hop on and assume they'll pay later. Inspectors board without warning, and riding without a valid ticket costs DKK 750, roughly $112 at the October 2026 rate of 6.6815 kroner to the dollar. Buy in the DOT Billetter app or at the platform machines before the train pulls in. Skip the taxi rank outside Terminal 3 too: a cab into Indre By tends to cost DKK 300 or more for a trip the Metro makes for a fraction of that.

Card terminals and airport ATMs in Copenhagen run a quieter scam. If a screen offers to charge you in dollars or euros instead of kroner, that is dynamic currency conversion, and the markup tends to be 3 to 7 percent. Always press DKK. Denmark is close to cashless, so skip the Forex exchange booths at Kastrup entirely: almost every Lagkagehuset bakery and 7-Eleven takes cards, including Apple Pay. Tivoli Gardens, open since 1843, is worth an evening, but the costs add up fast: the gate ticket doesn't include the ride pass, and a beer and a hot dog inside can top DKK 150. Go after dark, when the Halloween lanterns are lit and the paths smell of roasted almonds, and skip the ride pass unless you have kids with you. Pack for the October wind rather than the thermometer: at 7am today it read 10.5°C but felt like 6.5°C, and the gusts across Langebro feel colder than that.
