What's Open in Copenhagen on a Monday

Roughly half the Copenhagen Card's venues shut on Mondays, which is the most common way a trip loses a day. 42 of them do not — 27 with no weekly Monday closure at all, and 15 more that open on Mondays for part of the year. Which list applies to you depends on your dates, so both are here.

Planning Around It

What this means for the card you buy

Do not start a 24-hour card on a Monday
  • A 24-hour card starting Monday morning spends most of its life against closed doors if your list is mostly museums
  • Start on a Tuesday instead, or pick a longer duration so the Monday is absorbed rather than wasted
  • See how many days of card to buy for the arithmetic
Mondays suit the big-ticket venues
  • Copenhagen Zoo is the most valuable single attraction on the card, and it never closes
  • Experimentarium is the second most expensive, and it opens every day including Christmas
  • A Monday spent on those two extracts more value than an average museum day does — see whether the card pays off
Transport runs normally
  • The Discover card covers metro, trains and buses on a Monday exactly as on any other day
  • That makes a Monday a good day for a day trip, where the journey is half the value
  • Frederiksborg Castle and the Viking Ship Museum are both open Mondays and both a train ride out — see what the card covers on public transport
With children, the Monday is easy
  • The zoo, Experimentarium, the Planetarium and Ripley's are all open Mondays
  • That is a full family day without touching a closed museum
  • See the Copenhagen Card with kids
Common Questions

Mondays in Copenhagen

What is open in Copenhagen on a Monday with the Copenhagen Card?

27 card venues have no weekly Monday closure at all, including Copenhagen Zoo, Experimentarium and the Museum of Copenhagen. A further 15 open on Mondays for part of the year — Kronborg from May to October, the National Museum from April to October. That is 42 possible Monday visits in total.

Are Copenhagen museums closed on Mondays?

Many are, and it is the single most common way a Copenhagen itinerary goes wrong. Roughly half the card venues close on Mondays year-round, which is why the two lists on this page are worth checking against your dates before you buy a card that starts on one.

Should I start my Copenhagen Card on a Monday?

It is the weakest day to start on if your list is mostly museums, since a 24-hour card that begins on a Monday morning spends most of its life against closed doors. Starting Tuesday, or building the Monday around the zoo and the science venues, gets more out of the same card.

Is Copenhagen Zoo open on Mondays?

Copenhagen Zoo opens every day of the year, Mondays included, and it is the most valuable single attraction on the card. Experimentarium does the same, staying open through Christmas and New Year, which makes the pair the dependable answer to a Monday with children.

Which castles are open on Mondays in Copenhagen?

Frederiksborg opens every day of the year. Rosenborg opens Mondays in summer and closes them in winter, Kronborg opens Mondays May to October, and the Christiansborg Reception Rooms open Mondays 6 July to 16 August 2026. Check the dates against your trip.

For everything else the card opens, see the full attraction list and what's included.
