St. Augustine to Knoxville: Scenic Road Trip Guide

St. Augustine, founded in 1565, is the oldest continuously occupied European settlement in the continental United States. Your journey begins at the Castillo de San Marcos (29.8975° N, 81.3114° W), a 17th-century Spanish fort, and ends in Knoxville at the Sunsphere (35.9606° N, 83.9207° W), a 1982 World's Fair icon.

The 550-mile route combines I-95 north to I-26 west near Charleston, then I-40 west to Knoxville. Driving time is 7–8 hours without stops, but plan for a full day to savor attractions.
