Head outside and explore nature for free during National Public Lands Day.

All national parks that charge an entrance fee will offer free admission to everyone on Sept. 27, 2025.

Visitors who volunteer on National Public Lands Day will also receive a free national park one-day pass to any national park site.

Certain in-park projects may provide a fee-free day coupon to be used on a future date.

Since 1994, the fourth Saturday of September has become the nation's largest single day of volunteer action, according to the National Park Service . Last year, events at more than 130 national parks drew 7,600 volunteers donating 41,500 hours of service.

To find out where you can volunteer, go to Volunteer.gov for events at national parks.
