Through the Every Kid in a Park program, all fourth graders can get into national parks for free. It’s pretty easy and available starting in September each school year. The pass typically covers entrance for the whole family or car load. Certain rules and stipulations may apply so make sure you read over all of the details before you visit a park.

We visited Vicksburg National Park back in September for free! It was great. Make sure you don’t loose the pass they give you at the first park. You’ll need it to get into parks all year long!
