This is a full colour exciting guidebook for the middle grade boulderer, that is both comprehensive and seeks out the quieter and less visited parts of the giant Fontainebleau forest. There are over 2500 problems in the book, and all are mapped using the latest GPS technology to get incredible accuracy. This is illustrated in the maps of the boulders that are easy to use, and are in full colour throughout the book. The text is repeated in both French and English, but with variations to suit the comic styles of each language. The book is also rich with a whole array of icons to amuse and give warning when a problem is high enough to turn from a highball - into a DEATHBALL! There are around 270 colour photographs that illustrate many of the hardest problems in each particular area (In the easier grades of course 3a-5c). The book has a full grade chart for those not used to the Font grades and are more familiar with V grades. It also shows the comparative grade suitable for your sport climbing ability. All the local campsites are included, plus local shopping locations. If it is your first visit to the area, then this book is an ideal introduction becuse it is designed specially for those not familiar with finding the boulders in the forest. All of the problems were climbed for the book and have been re-graded. Much amusement will be had in comparing our new grades with some of the older and more traditional sandbags, but hopefully it will give the newcomer a fairer understanding of the fiendish difficulty undertaken in just a couple of metres of climbing.Fontainebleau is huge, and has around 30,000 problems, so putting everything in a single book would give you a gigantic telephone directory. The area is so rich in different climbing styles and levels, that it demands specific books for different interests. We have concentrated on collecting a set of 2500 problems that work together and should appeal to boulderers that like a flowing approach and nothing too powerful or dynamic.
