Junior Rangers: Each park has its own program to help children learn about its unique features. Most include an activity booklet and requirements such as taking a hike, participating in a ranger-led program, or picking up litter. Kids will enjoy the activities, but the real thrill is earning their Junior Ranger badges. Learn more at any park Visitor Center or at www.nps.gov/learn/juniorranger.htm.
Passport to Your National Parks: This pocket-sized book includes a map plus information and photos about each region's parks. As you visit national parks, monuments, and historical sites, stamp your passport with a unique cancellation mark, similar to international passport stamps. Purchase your Passport for $7.95 at any national park or at www.eparks.com.
