There are 63 national parks. Not 400-odd, which is the number of units the Park Service manages, and not 61, which was the count before 2019. Sixty-three, and this is all of them, grouped into the seven regions ParkStamp uses.
People have been keeping count of their national parks for decades, most famously in the little blue book of ink cancellation stamps collected at visitor centers. ParkStamp is not a replacement for that. It is the version that lives on your phone, remembers the dates for you, and reads your old photos to find the parks you forgot you had already been to.
Every park below has its own original illustration, drawn in the WPA poster tradition. Recording a visit is free for all 63. The artwork is the part you choose to collect.
