There are no user or entry fees for the Santa Fe National Historic Trail. Nominal fees may be charged at some trail-related federal, state, or locally owned historic sites and interpretive facilities.

Entry fees are charged at the National Park Service areas on the Santa Fe National Historic Trail. These areas are Fort Larned National Historic Site in Kansas, Bent's Old Fort National Historic Site in Colorado, and Fort Union National Memorial and Pecos National Historical Park, both in New Mexico.

The National Park Service is participating in the new Interagency Pass Program, which was created by the Federal Lands Recreation Enhancement Act and authorized by Congress in December 2004. Other participating agencies include the Bureau of Land Management, USDA Forest Service, Fish and Wildlife Service, and Bureau of Reclamation.

Information about purchasing the new America the Beautiful Passes (as of January 1, 2007) is available on this website. There are no fees for visiting the national historic trails, but some trail resources and sites are on federal lands managed by other agencies that do collect these fees.
