National Parks Passport Program
The National Parks Passport program is a great way to explore the over 400 units of the National Park Service. Purchase your passport book at the Mississippi River Visitor Center--or most national park visitor centers--and then obtain stamps for each park you visit. Passport books may also be obtained online at the Eastern National store. Stamps are available at most visitor centers, or ask a ranger where you can have your passport book stamped. Almost all parks have at least one stamp.
