Charleston, SC to Gulfport, MS: A Road Trip Guide

The route from Charleston, SC to Gulfport, MS spans roughly 620 miles along US-90 and I-10, crossing the lush Lowcountry, the Georgia coast, and the Florida Panhandle before reaching the Mississippi Gulf Coast. This drive typically takes 9–10 hours without stops, but the journey is dotted with barrier islands, historic forts, and seafood shacks that demand exploration. Notably, the route parallels the Gulf of Mexico for over 200 miles from Mobile to Gulfport, offering continuous water views.

When planning, consider the seasonal hurricane risk (June–November) and afternoon thunderstorms common in summer. The best stops along Charleston, SC to Gulfport, MS include Savannah’s historic district, the Okefenokee Swamp, and the USS Alabama in Mobile.
