Detroit to Aiken Road Trip: Ultimate Guide

The drive from Detroit, MI to Aiken, SC spans roughly 750 miles, tracing a diagonal slice through the industrial rust belt to the pine-shaded sandhills of the South. Interstate 75 south to Cincinnati, then I-71 and I-75 south through Kentucky, Tennessee, and into South Carolina.

An obscure fact: Aiken's racetrack, the Aiken Training Track, was built in 1912 and is one of the oldest continuously operating horse training facilities in the US. The route crosses the Fall Line, a geological boundary separating the Piedmont from the Coastal Plain, visible in the changing soil and forest types.
