You can get in to more than 100 national parks for free on one day in August
(NEXSTAR) — For one day only in August, you can get into any of our national parks for free.
There are seven such days throughout the year in which free admission is offered to everyone at National Park Service sites that typically charge an entrance fee. This year, those dates include January 9, which was a National Day of Mourning for President Jimmy Carter; Martin Luther King, Jr. Day on January 20; April 19, to commemorate National Park Week; and June 19 for Juneteenth.
Monday, August 4, marks five years since President Donald Trump signed the Great American Outdoors Act. Ever since, parks that otherwise charge entrance fees have waived their cover charge. Fees are still required for overnight camping, cabin rentals, transportation, group day use, and use of special areas.
After Monday, the next scheduled free entrance days are September 27, for National Public Lands Day, and Veterans Day, on November 11.
Which national parks charge entrance fees?
Of the 475 sites within NPS’s purview, 106 require an entrance pass.
In some cases, the fee applies only at certain times. For example, between early June and the end of October, there is no per-person cost to get into Adams National Historical Park. Others may charge only by vehicle rather than per-person fees.
Below are the national parks that would otherwise charge you to get in, but won’t be on Monday, according to NPS.

Why do some national parks charge entrance fees?
While it’s true that your federal income taxes do, in a way, fund the National Park Service, your contributions are relatively small in comparison to the agency’s needs. Entrance fees are used to “enhance visitor experience” under the Federal Lands Recreation Enhancement Act.
“At least 80 percent of funding from recreation fees stays in the park where it is collected, and the other 20 percent is used to benefit parks that do not collect fees or parks which generate only a small amount of revenue,” the National Park Service explains.
Fees are established based on a structure the agency uses that “simplifies and standardizes entrance fees across parks of similar types.” Rocky Mountain and Zion, for example, are both large and well-visited parks that have park-specific annual passes of $70, a per-vehicle fee of $35, a per-person fee of $20, and a per-motorcycle fee of $30.
Many parks also explain how they use the entrance fee funds. At Death Valley, for example, revenue from entrance fees has been used to design Braille park brochures, repair damages at a beloved feature, and support custodians and emergency medical services.
