The National Park Service works with federal agencies, state and local governments, organizations, tribes, and private individuals as partners to administer the California National Historic Trail. These partners help provide opportunities for visitors to learn about the significance of the trail, and assist in our efforts to protect and preserve trail resources, historic view shed, and the trail landscape.
