The directions and maps are easy to follow, even for someone with a pathologically bad sense of direction (me). This is not the most comprehensive book out there, but it is the most user-friendly and readable one I've found. There's a good diversity of trails here in location and difficulty. The book tells you how crowded each trail is likely to be and describes the trail, the flora/fauna, other trails that connect, etc. in a few pages per trail.
