Aiken to New Albany Road Trip: Deep South to Ohio Valley

This 660-mile route from Aiken, SC (33.5604° N, 81.7246° W) to New Albany, IN (38.2856° N, 85.8241° W) traces the Southern fall line into the Ohio Valley. You'll traverse state lines from South Carolina through Georgia, Tennessee, Kentucky, and finally Indiana. The driving time is about 10 hours without stops, but plan for 12-14 with exploration.

The heart of the drive follows interstates I-20, I-75, I-64, and I-71. But the best memories come from detours: from the red clay flats of the Palmetto State to the rolling hills of the Bluegrass.

Natural Landscapes & Attractions

From the sandhills of South Carolina to the Appalachian foothills and the Kentucky Karst plains, the scenery shifts dramatically. Key natural highlights: J.

Climatic Conditions & Route Aesthetics

Spring and fall offer mild temperatures (55-75°F) and stunning foliage, especially through the Cumberland Gap region. Summer brings heat and humidity (90+°F) with afternoon thunderstorms in the Appalachians. Winter driving is manageable but watch for black ice on I-75 near Jellico, TN.

Pet-Friendly Framework

Most motels along I-75 and I-64 allow pets (e.g., La Quinta, Motel 6) for a small fee. Rest areas have pet grass areas. In Kentucky, Boone Station State Park has dog-friendly hiking. Note: Mammoth Cave does not allow pets on tours, but kennels are available.

• Pet relief spots: every interstate rest area
• Dog-friendly attractions: Keeneland Race Course (dogs in the paddock)
• Carrier tip: safety belt harness for medium dogs

The Kentucky Welcome Center at I-75 MM 164 (near Williamsburg) has clean restrooms and picnic tables.
