Set out late May 2010 to walk the length of the GR10 solo, I took this guide, the ciccerone guide and also a couple of maps.
After only a couple of days I left the Ciccerone guide behind and only used the maps when the snow prevented me from continuing on the path or when I just wanted to check out other areas.
This guide is brilliant, it points out areas that may be tricking to navigate, gives information on where to stay on the route, it covers alternatives and also sections of the GR11, all in one small book that fitted perfectly into my pockets. I met many lost French people using the French Randonneurs guides (4 books) and helped them out along the way.
The pricing for the Refuges and gite d'etapes etc are now out of date, but that is to be expected.
With this guide, the route markings, 4 x 1:100 scale maps, good kit and very poor French I had one of the best trips of my life....it is a beautiful place with great people.
Looking forward to my next adventure....
