National Park is a passport for your visits to all of the parks in the US National Park System. This includes National Parks, National Monuments, Historical Sites, Recreation Areas, National Monuments... 477 in all. You can view pictures, descriptions, locations and links to National Park Service web sites for more information on all of the parks.

You can also use this application as a checklist to record which parks you have visited along with the date, your notes and a photo to mark the visit: a picture of the park's passport stamp, a picture of you in front of the visitor's center or whatever you want.

You can share your list of visits with your friends and see what parks they have visited.

This is *not* a guidebook. This is similar to the National Park Passport book that you can buy for $8.95 and collect stamps.
