With the blue UK travel documents you can’t go to Denmark. If you go there, they will reject you and send you back again to the UK.

It’s happened to me on March 2023. I went to London Stansted airport (Ryan air). Even though they have a counter for visa check, they didn’t say anything to me. I was admitted into the flight and flew to Denmark. When I arrived in Copenhagen, immigration said that I needed a visa with this passport and they refused entry and sent me back again to UK.

It depends on the precise type of travel document. If it is a “convention travel document,” with this cover, the answer is yes.

Section IV of this document (“Fritagelse for krav om visum”) details 26 categories of people who are exempt from the visa requirement in Denmark. They include citizens of a number of visa waiver countries, holders of a residence permit in another Schengen country, passports for some of the many many British nationality types (British citizen, BN(O), BOTC, BOC, BPP and British subject), laissez-passers from certain international organizations, etc. It does include aliens’ passports from a few countries, but not British ones.

Item 19 is: Holders of valid travel documents issued under the convention of 28 July 1951 relating to the status of refugees or the agreement of 15 October 1946 relating to the issue of a travel document to refugees, issued by an EU or Schengen country, if the holder is a lawful resident of the issuing country.

Some other categories you might qualify for depending on your particular circumstances, based on a casual reading, are:

20. Participants in school trips within the EU, if the group is led by a teacher who has been issued a specific form for EU school trips.

21. Stateless and refugees under the age of 21 named in a collective passport.

22. Holders of travel documents issued by an EU or Schengen country pursuant to the 1954 convention relating to the status of stateless persons, who are resident in the issuing country.
