Every Kid in a Park offers a National Parks 2018-2019 Pass for free to the families of interested 2018-2019 fourth graders. That's $80 less than buying a regular National Parks annual pass at a park. It grants admission to more than 2,000 federal recreation sites, including Yosemite, Yellowstone, and Grand Canyon. The pass expires on August 31, 2019.

Note: For families, each pass admits all children under 16 and up to three adults for free.
