National Public Lands Day

Explore a new park or protected area for free during National Public Lands Day. Seven federal agencies as well as nonprofit organizations and state regional and local governments participate in the annual day of caring for public lands. National Public Lands Day keeps the promise of the Civilian Conservation Corps, the "tree army" that worked from 1933-1942 to preserve and protect America's natural heritage.
