Great coffee table book, almost useless as a practical climbing guide. Lots of lovely glossy photographs but no real substance with regards to route descriptions or area guides. One needs a PhD to decipher the symbols which are over complicated. There are also gratuitous 'down the top' shots of attractive young ladies which are great in the privacy of one's own home but unnecessary when actually out there bouldering. A poseur's handbook, if you are thinking of going out to Font for a climb I would recommend Jo Montchausee and Jacky Godoffe's well established guide, written by experienced bleausards, or in the case of a flying visit the Stone Country 'Essential Fontainebleau' bouldering guide.
We got this guide before a visit and found it more than adequate to get us to and round an appropriate set of routes for our time there.
Each circuit described is given some general information and a few very good photos, and then a listing for every route on the circuit. The actual listings are overly complicated, with 5 or 6 tiny, complex and unclear icons beside each one which waste space and, to be honest, are best ignored.
There are a vast number of circuits described, although no book could cover every bit of the area.
