Great detail and GPS coordinates point out points of interest are a great feature. Love the layout of each trail that is highlighted. I have the spiral bound version and would enccourage everyone to get it. I can oen up the book to the trail I need, drop it in a gallon ziplock bag and throw it in my fender bag. Easy to grap and not have to fumble through the book look for the right page.
