Copenhagen is the best home base in Scandinavia for a trip that covers more than one country. Sit at Central Station and six genuinely different day trips fan out from the same platform: cross into Sweden in under 45 minutes, stand inside a reconstructed Viking ship in half that, or walk Hamlet’s supposed castle by lunchtime. None of the six needs an advance ticket. This guide is the base-camp version of Copenhagen, what each trip costs, how long the ride actually takes, and which two to cut if you’ve only got 2 days.

Copenhagen rewards three days more than most Nordic capitals: Nyhavn’s canal houses, Tivoli Gardens, and Rosenborg’s crown jewels all happen without leaving the city limits. Skip the Little Mermaid at midday, it’s a genuinely small 1.25m bronze that draws its worst crowds mid-morning, and go before 9am instead. Denmark uses the Danish krone, not the euro, pegged at roughly 7.46 DKK to 1 EUR and 6.5 DKK to 1 USD, and this is one of Europe’s most expensive capitals, so treat the budget table below as the real number, not a lowball estimate.

The Round Tower (Rundetårn) doesn’t pull the crowds Rosenborg or Tivoli do, and that’s exactly the case for climbing it: 60 DKK, no advance ticket needed, and a wide spiral ramp instead of stairs that takes about 15 minutes at an easy pace. Christian IV built it in 1642, making it Copenhagen’s oldest surviving observatory building, though the observatory itself is closed for restoration until October 2026, so right now the climb is about the ramp and the view, not stargazing.
