National Parks Service passport stamps are a fun and free way to remember your visits to national parks. Collect your stamps in a special NPS Passport book or on park brochures, Junior Ranger books, or even just plain old paper!

Northern Plains National Heritage Area invites you to get stamped at our gift shop, located at 1700 River Rd., Bismarck, ND, where you can also purchase an official NPS Passport book.
