Established in 1994 and held annually on the fourth Saturday in September, National Public Lands Day is the nation's largest single-day volunteer effort.

It celebrates the connection between people and green space in their community, inspires environmental stewardship, and encourages use of open space for education, recreation, and health benefits. This year, National Public Lands Day falls on September 26, 2020.

There are many ways to participate in National Public Lands Day.

Visit Theodore Roosevelt National Park for free.

Take part in a volunteer work project. If you volunteer on this day, you will receive a fee-free day coupon to be used on a future date. See the list of National Public Lands Day events and volunteer events here!
