Steve Ashton has compiled a fairly comprehensive catalogue of Snowdonia walking routes within this book. Much the same as other books dedicated to walking in North Wales this one concentrates on the Carneddeau, Glydereau and Snowdon ranges, there are a few other less known routes at the end of the book but they have a kind of "afterthought" feel to them.
For the experienced walker/scrambler this publication could provide some useful information for trying out new routes but for the less expereinced or novice walker it could prove somewhat misleading and possibly even dangerous.
There are Ordinance Survey map extracts to accompany each walking route but in the grand scheme of things they aren't really practical for navigating out in the mountains and only provide an indication of the area to look at on the full scale map that all walkers should have with them.
Mr Ashton's timings are a little optimistic to say the least and could easily lead the novice into thinking a route can be completed in just a few hours when in fact it may well take them all day, this could become dangerous in the shorter winter days and result in someone trying to navigate their way down a mountain in the dark. For safety's sake I would advise doubling the timings in the book!
Additionally Steve Ashton's descriptions need more of a frame of reference and standard to them, he may well think that a particular route should provide no problems or involve no real scrambling, but others may well think that working their way over rocks, scree and boulders using their hands is indeed scrambling and could prove problematic.
A lot of the routes in this book could be considered as classic I guess and many more seasoned Snowdonia walkers will have probably completed all of them by now. If this publication were aimed at the experienced walker then it could certainly be considered sufficient for the job, but it is not, there is nothing in the book to indicate the experience level needed to complete the routes safely and so one would have to assume it is aimed at anyone. As such this makes it potentially dangerous, should a first time visitor to Snowdonia pick up this publication and head for Crib Goch, the North Ridge of Tryfan, Bristly Ridge or Y Llewedd?? I certainly hope not!
