Gatlinburg to Wilmington Road Trip Guide: Best Stops & Routes

Driving from Gatlinburg, Tennessee to Wilmington, Delaware covers roughly 700 miles of diverse terrain. The journey traverses the spine of the Appalachian Mountains, crosses the historic Mason-Dixon Line, and ends at the tidal banks of the Delaware River.

Today, Interstate 81 and Interstate 95 form the backbone, but detours along the Blue Ridge Parkway or US 11 reveal a slower, richer America.
