This is a hefty tome of over a thousand pages as befits a country as large and diverse as France. The first fifty or so pages cover the usual general topics such as a month by month guide, suggested itineraries and the obligatory fifteen top sites which are largely subjective, but included the obvious ones such as Mont St Michel and the Eiffel Tower.
The meat of the book is in the next 850 pages and is divided into the 19 regions of France. Generally what is covered are the main attractions within the area together with where to eat, where to stay and other relevant information. Looking at the Loire, which is an area I am familiar with, the general attractions of the area were very adequately covered and there was information on such essentials as opening times and pricing. The information on eateries was generally OK, but on occasion did seem a little out of date to me - I imagine it is asking a bit much to expect a book of this size to be totally updated for each edition. Personally I am not normally too interested in the accommodation data as I find sites such as Tripadvisor give much more accurate and timely information than a guide such as this.
Towards the end there is quite a lot of general information including the history of France, architecture and a very useful survival guide, which has been a recent and welcome addition to Lonely Planet guides. Overall I found this to be a very comprehensive guides, and whilst if you are visiting Paris you may find a specific guide covering the city more helpful, this will contain everything you need for a trip to France.
