If you are obsessed with history, ancient monuments, architecture and relics this is probably the book for you.
As a tourist guide, to tell what is worth seeing/photographing, i.e the aesthetics, I find it virtually useless. It does give routes, with some warnings about where congestion may occur in the summer and identify some parking spaces, but the rest is generally vague and somewhat inconsistent. Even the restaurant prices are given in Francs, in a used copy which may not be the latest edition but a book with a 2001 copyright.
This review is in the context of having already booked accomodation and wanting to plan a detailed itinerary, with intensive and diverse photography in mind, in advance, this being my standard use of guides over many years.
This was my first experience of the series and, as its emphasis is as distant from my interests as I have found in a guide book, is expected to be the last.
