Celebrate National Public Lands Day with FREE entrance to all 401 national parks this Saturday, September 28. The 20th annual event encourages everyone to volunteer on their public lands and enjoy the great outdoors!

National Public Lands Day is the nation's largest single-day volunteer effort for public lands. Seven federal agencies as well as nonprofit organizations and state, regional, and local governments participate in the annual day of improving the health of public lands and encouraging shared stewardship through volunteer service.

Along with free entrance to national parks for the public on September 28, all National Public Lands Day volunteers receive an additional one-day pass for free entry to any participating federal public land to use anytime within the year. Other federal agencies waiving fees on September 28 include the U.S. Fish & Wildlife Service, the Bureau of Land Management, the Bureau of Reclamation, the U.S. Army Corps of Engineers, and the U.S. Forest Service.
