About borders and countries from where you can enter Denmark as a tourist
People resident outside of Denmark can enter Denmark with a worthy purpose and proof of a negative COVID-19 test taken no more than 24 hours before entry. If you travel by plane, the test must have been taken less than 24 hours before boarding the plane. The rule lasts until and including 17 January 2021.
As the things change fast, we encourage you to see the Danish authorities' latest information on entering Denmark here.
Denmark's borders are only open for travellers from countries (and in some cases regions) that meet certain criteria, including a certain number of covid-19 patients per capita. Each Thursday, the list of countries and regions classified as open or closed is published. See if your country of residence is considered open or banned and find the authorities' updated information on travelling into Denmark here.
Travellers from countries defined as banned on the list must expect to be denied entry at the Danish borders, including airports unless they have a worthy purpose for entering. See what is considered a worthy purpose by the Danish authorities in here.
If you are in Copenhagen, we urge you to follow instructions from the authorities which include these measures (valid until at least Jan. 2, 2021)
New guidelines at Copenhagen Airport
As of June 15, 2020 new guidelines for safe travel became effective in Denmark's airports. Besides including compulsory medical face masks at the terminals, the guidelines issued by The European Union Aviation Safety Agency (EASA) apply to all European airports and include a set of things you need to consider before flying.
See this practical guide on safe travel through Copenhagen Airport - including the option of free covid-19 test at the parking area P5 outside of Terminal 3.
