Volunteers looking to spend a Saturday cleaning up a national park this fall now have five weekends to choose from, not one.
National Public Lands Day itself falls on September 26 this year, the fourth Saturday of September, same as it's been since the event started in 1994. But the National Park Service and its partner, the National Environmental Education Foundation, are running this year's volunteer events from September 12 through October 10. The longer window gives individual parks room to schedule cleanups, trail work, and habitat restoration around their own weather and their own volunteers.
On its event page, the Park Service still calls National Public Lands Day the country's largest single-day volunteer effort. The projects now run across five weekends. This year's theme, "Caring for Our Shared America," ties into the nation's 250th anniversary.
National Public Lands Day isn't on the Park Service's official list of fee-free entrance days for 2026, which covers Presidents Day, Memorial Day, Independence Day weekend, the agency's own birthday, Constitution Day, Theodore Roosevelt's birthday, and Veterans Day. Some individual parks hand volunteers a coupon that waives the entrance fee, but that's a park-by-park courtesy this year, so check with the park before counting on free admission.
To find a project, the Park Service points volunteers to its events calendar and to Volunteer.gov, which also lists opportunities on public lands beyond the park system.
The agency also asks volunteers to tag their posts #NPLD and #NPSVolunteer, and to review Leave No Trace guidelines before heading out.
