Natchez Trace Parkway —Tennessee.

The Natchez Trace Parkway follows an ancient path used by Native Americans, Kaintuck boatmen, and Andrew Jackson's army. The 444-mile parkway from Natchez MS to Nashville TN passes through rolling hardwood forest, Civil War sites, and mounds thousands of years old — with zero traffic lights, zero commercial traffic, and a 50 mph limit. It's the closest thing to a motorcycle-only corridor in America.
