Auto Tour Route Interpretive Guides

These are state by state guides that provide an overview of local trail history and driving directions to suggested points of interest that provide interpretive media and/or educational services.

Auto Tour Route Interpretive Guides can also be found at many travel and tourism centers along the historic trail route.

The Auto Tour Route Interpretive Guide series are a work in progress. Below are the interpretive guides currently available. As new guides are developed, they will be posted here.
