National Geographic"s familiar golden-yellow border bespeaks the quality color photographs (250 of them!) that make this guidebook as fun to look at as it is to read. More than 200 state parks in all 50 states are skillfully reported on in classic National Geographic style. Each section includes a park overview, driving directions, suggestions for what to see and do, and camping and lodging ideas. After these parks were chosen from the recommendations of state-park directors, National Geographic sent regional travel writers to work exploring, collecting firsthand details, and gleaning insider information from park staff. Clearly marked maps are easy to use and lead the reader through many of the selections, detailing important sights, trails, and campgrounds. Sidebars offer extra advice and historical or environmental accounts.
