This book is the ideal size to carry with you on a walk, and provides all the detail neded to follow the walk. Points of interest are highlighted, and often illustrated with excellent photographs. My only gripe is that the photos are a little small for my rather old eyes. Larger photos would have made the book bulkier or they would have to eliminated some - so I suppose the compromise is about right for most people.
I have found that the walks are accurately described with the time taken predictable from the book.
The unusual feature of the book is the provision of GPS way point data, so by loading the way points into your gps before setting off, you can simply follow the route knowing you are exactly on the intended path. I found this reassuring, and it certainly added an element of interest to the walks.
Overall, a book I heartily recommend, I will be looking out for more books in the series.
