I am looking for an English-speaking tour guide to show me the historical and cultural features of Burgos. any recommendations?
Check with the Tourist info there. I did see some English tour guides walking around in the cathedral with just 2-4 people, so they must exist for private tours of the city.
https://www.guiasdeburgos.es/en is the official guide association.
Thanks to both of you for being so responsive. jtm
