Celebrate 30 Years of National Public Lands Day with Wyoming State Parks, Historic Sites, Trails and Outdoor Recreation

Join us in celebration of the nation's largest single-day volunteer event for public lands this September! Help restore, improve, and enjoy Wyoming State Parks, Historic Sites and Trails across the state by attending an upcoming National Public Lands Day event in your area.

Established in 1994 and held annually on the fourth Saturday in September, National Public Lands Day (NPLD)  is a nationwide initiative led by the National Environmental Education Foundation.  This annual celebration brings out hundreds of thousands of volunteers to help restore and improve public lands around the country. NPLD is also a “Fee-Free Day”—one of only five days a year when entrance fees are waived at national parks and other public lands.

This year, NPLD is celebrating 30 Years of Care and Community. In the past decade alone, over 1 million volunteers have donated almost 5 million hours of their time for public lands, worth an estimated $133 million. These efforts are crucial to preserving our natural resources for future generations to enjoy.

“Not only does National Public Lands Day give us the opportunity to give back and to take care of the public spaces we enjoy recreating on throughout the year, but it also gives us the chance to connect with our communities and to create kinship amongst those volunteering,” states Laurel Stephens, Outreach Coordinator for Wyoming’s Office of Outdoor Recreation.

In honor of this annual celebration, day use and entrance fees will be waived at all Wyoming State Parks and Historic Sites on September 23rd.

This year, ten Wyoming State Parks and Historic Sites will also host National Public Lands Day events from trail improvement projects, nature walks, park clean-ups and more. Event details for participating sites are as follows:
