Kids in Parks

National parks are places where kids can dream up great adventures! Taking in amazing scenery. Testing out new skills. Exploring places kids may have only heard about. But most importantly, creating new memories with friends and family.

Our public lands are our public commons. They belong to all of us as part of our natural and cultural heritage. They remind us of a larger world that has existed long before the arrival of humans and will survive long after we are gone. –Terry Tempest Williams, Author & Conservationist
