Denmark welcomes fully vaccinated visitors from EU, Schengen and OECD nations (which includes the UK and USA). In most cases, for vaccinated visitors there is no mandatory quarantine period in Denmark, but please check carefully on the Danish Government's info website, as there are some exceptions. If you are not fully vaccinated but have a negative corona test, restrictions vary according to which country you are travelling from.
The corona passport is reintroduced in Denmark. This means that you'll need a valid corona passport or similar documentation of vaccine, previous infection or recent negative test to enter restaurants, nightlife, cultural venues and more. Additionally, face masks are mandatory on public transportation, in stores and supermarkets, in hospitals and more. Check the latest updates on Covid travel rules below.
