A few times a year, the U.S. Department of the Interior makes it free for everyone to enter the National Parks. The National Park Service has six days you’ll get free entrance in 2025, and the next free day is Thursday, June 19, where you’ll be able to enter any of the U.S. National Parks without fees.
While not all National Parks charge admission, more than 100 parks have entrance fees, typically between $5 and $35 per vehicle. So if you’ve been hoping to visit a popular National Park this year, one of these free days is an ideal time to do it.

National Park Free Days are 1-day events where over 100 parks waive admission fees.
Check your schedule to see when you might visit one of the National Parks during one of the half-dozen free admission days throughout the year. Over 100 parks in 39 states waive their admission fees for one day so you can enjoy at no cost. You can find the list of participating parks by state below.
The next National Park Free Day is on Thursday, June 19, 2025.
We see around six free admission days each year. In 2025, these are the days the National Park Service isn’t charging any entrance fees:
Jan. 20: Birthday of Martin Luther King, Jr.
April 19: First day of National Park Week
June 19: Juneteenth National Independence Day
Aug. 4: Anniversary of the Great American Outdoors Act
Sept. 27: National Public Lands Day
Nov. 11: Veterans Day
Before you head out, make sure your favorite park is open.
The free admission only applies to the parks that are open, of course. Factors like weather and construction can alter a park’s status; for example, one of the most popular parks, Yellowstone, closed in June 2022 after severe flooding.
The National Park Service closure list changes all the time, so check it before you plan your trip. And for a list of all the parks that participate in these free-entrance days, see our list below.
Get to know all the other park discounts and freebies.
Fourth graders get free admission during the summer (and their families too). Active-duty, retired, and reserve military members are always free at the parks. Learn about these and more National Park discount tips.
For last-minute trips, you’ll want to camp inside the park.
Most parks that allow camping have both reservable and first-come, first-served sites. Nightly fees range from $15 - $50 depending on your site and whether you need an RV hookup.
If you’re so last minute that you can’t get a reservable spot, there are always a limited amount of first-come, first-served spots. Check the individual parks’ websites to make sure campsites are still open.
Here’s a list of all the participating free-entrance parks.
