The Blue Badge is awarded only within the British Isles, but guides who are trained and qualified to a high standard are available in many countries throughout the world.

tourist-guides.net does not have information about individual guides at the moment and would therefore recommend that you consult the regional or national Professional Associations.
This page is being developed. So far the list is as follows:

Denmark
Ireland
Spain (Girona)

For the rest of the world a list may be found on the site of the World Federation of Tourist Guide Associations.

The main site is http://www.wftga.org/

The list of Members is on http://www.wftga.org/members/worldmembers.php
