Aiken to Bardstown: Ultimate Road Trip Guide

This 450-mile route traces the fall line from South Carolina's horse country into Kentucky's bourbon heartland. The drive follows I-20 west, then I-26 north, before hooking onto I-75 and the Bluegrass Parkway. A notable quirk: near the border of SC and GA, you cross the Savannah River at the exact point where the Eastern Continental Divide intersects the river, meaning rain falling on the left side of the road eventually reaches the Atlantic, while water on the right heads to the Gulf of Mexico.

The journey takes about 6.5 hours of pure driving time. But the question is it worth driving Aiken, SC to Bardstown, KY? Absolutely: this route offers a microcosm of Southern history, from horse farms to bourbon distilleries, with unexpected natural beauty along the way.

Interstate driving on this route is generally safe.
