On January 8th, Danish authorities adopted stricter measures as regards entry into Denmark, in an effort to limit the spread of COVID-19. Those who wish to travel to Denmark must have a worthy purpose and are required to have a negative COVID-19 test that is not older than 24 hours. These measures are in effect until and including January 17th 2021 with the possibility of extension.
As such, we strongly advise you to visit the dedicated Danish police's website before traveling to Denmark:
