Susie,
I was delighted to see your post as my wife and I are intending to walk from Cluny via Le Puy this year, commencing around mid August. So like Ashleygf I will be watching with interest any information that you are able to share.
I have seen reference to an ' Orange book' which provides details of this section, but I have not yet been able to purchase a copy. If you or any one reading this knows of a supplier who could post this to Australia, I'd be very appreciative.
With best wishes, David.
