I have completed just over half the routes in the book, and can honestly say that I have enjoyed every single one. I am lucky enough to live in the Peak so the weekend layout (Saturday/Sunday walks) hasn't been applicable, but I am sure that hikers visiting for a long weekend would find this very helpful. I also like the way that the walks are circular and ordered by starting point (ie Bakewell, Eyam etc). This really helps to 'centre' the experience.
My only criticism regards the format of the book. One thing I love about the Cicerone Guides is that they can be easily carried in a pocket and have a waterproof PVC jacket. Our book hasn't stood up very well to rainy Derbyshire weather and we've had to resort to photocopying pages to take with us. Saying that though, I would buy other books by Mark Reid, despite this one minor quibble.
