A simple alphabetical list of all the countries whose dark destinations are covered on this website can be found on the left-hand side, or, if you are viewing this on a smaller tablet or phone screen, on this separate alphabetical country list page.
Below is a grouping of all those countries by continent: Africa, Americas, Asia, Australia, Europe, plus Antarctica as well as the Atlantic and Pacific.
For destinations arranged thematically according to categories go here. Other groupings are also to be found in various lists, such as the darkometer ranking list.
If you can't find the country you're looking for, try going via the index – it could be that the country in question is listed here under a different designation; e.g. since Great Britain and Northern Ireland have separate entries of their own, you won't find the "UK" listed here, although it is of course covered, and e.g. England is subsumed under Great Britain. Similarly, dark places in states that no longer exist under their old name, such as the USSR or GDR, are now covered under Russia and Germany, respectively, while the old states that have ceased to exist as such may still be given a brief entry of their own in the glossary.
