The National Park Foundation (NPF) was chartered by Congress in 1967 to raise private support for National Parks, and to build a broad community of people who care about their parks. America's National Parks have a long tradition of philanthropy, and NPF is proud to continue that tradition today. As the insiders guide to unlocking the National Park experience, NPF is here to tell the stories of the National Park experience, and to educate and inspire people to get involved with their National Parks—whether through making donations, becoming volunteers, or simply helping to spread the word about America's greatest treasures.
