National Geographic Guide to the National Parks of the United States. This is our #1 "can't live without" resource! This book has about 8 pages for each of the 50+ Parks.  It includes maps, beautiful photos and history, but the most useful are the detailed descriptions of what to do in the Park. These "how to visit" sections contain great info on what trails to take, what overlooks to stop at and how long it will take you. We've learned through experience to trust their recommendations and take this book with us to every Park. To order, you can call National Geographic direct at 1-888-225-5647.
