Update: The National Park Service is turning 100! The fee-free day continues this year. See more on the website!
The National Park Service is turning 97. Admission and day-use fees at national parks are waived on Sunday, Aug. 25, so it might be a good time to plan a day trip. I visited Grand Canyon National Park on a fee-free day in September and saved $25.
Looking for a national park in Arizona?
- Canyon de Chelly National Monument, located in northeastern Arizona.
Of course, there are also national parks and monuments that never charge an entrance fee.
