The Natchez Trace Parkway leads you 444 miles through three states and 10,000 years of North American history. Established as a unit of the National Park System in 1938 and officially completed in 2005, the Parkway commemorates the most significant highway of the Old Southwest. The natural travel corridor that became the Natchez Trace dates back many centuries. It bisected the traditional homelands of the Natchez, Chickasaw, and Choctaw nations. As the United States expanded westward in the late 1700s and early 1800s, growing numbers of travelers tramped the rough trail into a clearly marked path. The ”sunken” sections you can walk along today are clear signs of historic use. In 1801 President Thomas Jefferson designated the Trace a national postal road for the delivery of mail between Nashville and Natchez.
