A book of 2 halves, the first 137 pages is an OK guide book giving a bit of description and background on the towns and sights of the Peak district. Perhaps some of those listed are hidden gems, but if so they remain hidden among the 'usual suspects'. There seems to be little that you couldn't pick up from freely available sources. Dotted on these pages are small adverts which point you to the back of the book.
The bulk of rest of is taken up with paid for content, adverts for Hotels, Restaurants, Tea Rooms etc.
Now, if I had picked this up for free, or a nominal cost, in a Tourist Office, I might think that was OK. But for something retailing a something close to a full price guide I think it is pretty poor.
Not recommended.
