Passport to Your National Parks

The program is run by Eastern National, a non-profit organization that operates bookstores in many park locations.

In 2006, for the program's 20th anniversary, the Passport Explorer was released, featuring a binder and larger pages.

Each region provides oversight and guidance to the park units within its geographic area.

The stamp sets, dating back to their inception in 1986, are still readily available at most park gift shops for under $10, or on the internet through Eastern National.

Each stamp would be mounted onto its respective page with a lightweight, black, adhesive-backed plastic sleeve.
