I took a number of guide books with me to Crete but due to the great layout and ease of use I kept on coming back to the AA Spiral Guide. The book clearly splits the island into Iraklio (the capital), Central, Eastern, and Western Crete. There are suggested points of interest for each of these areas as well as the usual information on where to stay, eat, shop and be entertained. At the start of each section you will find 'Getting Your Bearings' pages very useful to planning. At the rear of the book you will find suggested walks and drives - just giving you that little bit extra.
Finally I should point out that by being a 'Spiral Guide' the book can be opened out flat without closing itself or damaging the spine as you would a book.
I would highly recommend this guide especially at the price.
