Copenhagen is a real Christmas city and oozes of atmosphere during Christmas. Tivoli Gardens' Christmas market is a must, and on top of that you will find many more Christmas markets and activities.
If you are staying in Copenhagen between Christmas and New Year's Eve, please note that some attractions, shops and restaurants are closed or operate with shorter opening hours than usual. But no worries, there are still plenty of attraction that are open. Including these.
Julefrokost, gløgg, and smørrebrød: When spending Christmas in Copenhagen, there's really no way around indulging in those traditional culinary cravings that are such a big part of the season in Denmark.
