The Passport to Your National Parks program is a voluntary program that nearly all parks within the National Park Service (NPS) participate. Visitors can purchase their official NPS Passport and start recording their visits to NPS sites by stamping their passport with a rubber cancellation stamp. The cancellations, similar to those received in an international passport, record the name of the park and the date it was visited. There are currently over 500 sites with the NPS that participate in the passport program.
