Snowdonia's very best ridge walking is described in this guidebook, taking walkers through the Carneddau, Glyders and Tryfan, Snowdon range, Moelwyns, Nantlle, Rhinogs, Arans, Cader Idris. In describing the ridges the author has tried to be both readable and accurate, which should help to explain the unusual layout. The raw material of the route - map, information, route description - is presented in four no-frills pages, while the general chit-chat and photographs are allowed to follow on at their leisure. This means you have the option to glance through one or the other according to need, and without having to plough through an unnecessary amount of verbiage. Because the book is designed primarily for the hill-walking enthusiast, the author has commandeered space traditionally reserved for introductory notes and lengthy topographical descriptions (using photographs to help compensate in this latter respect) in order to explore the hill-walking experience beyond what is normally possible in a guidebook.
