Many families with young children enjoy purchasing a National Park Passport book and collecting stamps from each park, monument or historic area they visit.

The venerable program will get a new look in 2016 as America celebrates the 100th anniversary of the National Park Service.

The Passport to Your National Parks program will offer special centennial Passport cancellation stamps at national parks throughout the country in 2016.

The special stamp will print a round cancellation graphic with the name of the individual park around the top of the circle and "NPS Centennial" around the bottom. A middle line will read "1916-2016."

The special stamps will be available starting January 1 until the end of 2016.

Centennial cancellation stamps will also be available at various events associated with the Pasadena Tournament of Roses Parade, where the NPS will feature a pop-up national park. Visitors can get their passports stamped at the NPS Mobile Visitor Center at Decorating Places from December 27 through 31 and Post Parade from January 1 through 3. Stamps will also be available at Live on Green, a family festival also held in Pasadena from December 29 to 31.
