Hi
Who can offer some advice to a complete novice?
I'm going to visit Bordeaux for a week in September. I don't want to
pay for an organised tour but I would like to plan an itinerary to
include several chateaux.
I understand that I have to pre-book these visits but I have no idea
how to do this.
Can anyone recommend where to go and how to arrange it?

thank you
Dave B
