You’re planning a pilgrimage route. Which part of the world would you like to walk in?

I’d really like to cycle – rather than walk – and to go on a long route. Starting in Paris, then on to France, Holland and then back to Yorkshire, following the life of Queen Henrietta Maria. I am spending almost every day with her currently, writing her biography, and she seems a suitable companion for a pilgrimage: she was a devout Catholic and a remarkable and underestimated Queen of England, Scotland and Ireland.
