Boone to Hannibal: Ultimate Road Trip Guide

Leaving Boone, North Carolina, elevation 3,333 feet, you descend the eastern continental divide. The 755-mile journey to Hannibal, Missouri, birthplace of Mark Twain, traces the path of early American migration. You cross five states on I-40, I-81, I-64, and US-61, passing through the Appalachian Mountains, the Cumberland Plateau, and the vast Mississippi River Valley.

An odd trivia: near Paducah, Kentucky, you cross the Tennessee River exactly where the New Madrid earthquake of 1811 temporarily reversed the flow. This road trip offers a blend of mountain vistas, rolling farmland, and riverside towns. For tips on how to find the best stops and hidden gems between cities, consult the linked resource.
