Ciccerone guides are usually excellent, and the Isle of Wight is a great walking destination, but this guide does not make the most of it.
The guide is subtitled "Short walks and longer trails", and that is exactly what you get. 12 short walks of 2 to 4 miles, and 18 longer walks of 8 to 15 miles, plus the two long distance trails. So there are no walks in the popular 5 to 7 mile bracket for those who want more than a short stroll, but do not want a longer trek.
All the short 2 to 4 mile walks are circular, but only 5 of the 18 longer walks are circular. Of the 13 linear walks, only 4 give any indication of how to get back to your start point. I recently researched the first walk in the book, which although a great walk, has no direct bus link from the end point back to the start. So you either need to book a taxi, or take two cars - who takes two cars on holiday?
The contents page is almost useless, as it simply lists the walks by number, (Walk 1, Walk 2 etc) and gives no indication as to which walk is which, or where it is on the Island.
The coastal path is well described and mapped, but bizarrely the authors have chosen to describe the route anti-clockwise - surely clockwise is the better direction?
So do go to the Isle of Wight, and do go walking, but don't rely on this book. The book takes you to some great spots for walks, e.g Tennyson Down, so use this book for ideas, take the Ordnance Survey map OL29, and find your own routes.
Happy Walking.
