The Guide to the Blue and John Crown Mountains tempts and excites the uninitiated, informs and prepares the committed and provides a wonderful memoir for veterans of the experience of the National Park in Jamaica. From cover to cover, the reader is taken on a tour in time and space around and through the park. The opening chapters provide an overview, a big picture of the entire area. This is supplemented by descriptions of interesting places, trails, plants and animals. The sections on the human and geological history of the area provide that sense of time travel which weaves everything together into an interesting, informative and enjoyable pocket guide. The Guide to the Blue and John Crown Mountains is an invaluable contribution to Jamaica's conservation literature and movement, and will deepen an appreciation for the importance of the mountain ecosystem.
