National Historic Trails recognize diverse facets of history such as prominent past routes of exploration, migration, trade, communication and military action. The historic trails generally consist of remnant sites and trail segments, and thus are not necessarily contiguous.

Although National Historic Trails are administered by federal agencies, land ownership may be in public or private hands. Of the 11 National Historic Trails, nine are administered by the National Park Service, one by the USDA Forest Service and one by the Bureau of Land Management.

A color, topographical map of the entire trail can be downloaded from the "Maps" link found under Trail Directions.

The links found on the Plan Your Visit pages will provide information for enjoying these historic trails and suggest opportunities to learn about emigrant stories and experiences.
