I really do wonder how many of you planning to visit Britain, actually check out the official government tourism site? I have put the link below. Feel free to comment as to whether or not it is helpful or not and whether you would have consulted it had I not brought this to your attention.

England, Wales & Scotland also have separate sites - which I have listed below but don’t forget that they have separate forums for the UK nations on Rick Steves.

I would also add that many cities/towns as well as Counties also have ‘official’ sites. To find these, try a Google search with ‘visit *****’.
Of course, that depends if you already know the actual name of the county/town or city that you are interested in. (When I say ‘official’, I mean run by a local Council/ City Council and not a commercial organisation - although links may be provided to commercial organisations/hotels etc.)
