Charleston to Jekyll Island: Coastal Drive Guide

Charleston's historic charm gives way to the Lowcountry's maritime forests as you head south on US-17. The route to Jekyll Island spans roughly 190 miles and takes about 3.5 hours without stops. This drive crosses two state lines and passes through the ACE Basin, one of the largest undeveloped estuaries on the Atlantic coast.

The highway numbers shift at the Savannah River: once in Georgia, US-17 becomes GA-25 Spur, then I-95 South. The final leg uses GA-520 (Jekyll Island Causeway). Beware of the abrupt 45 mph limit on the causeway—a frequent speed trap.

Cell reception drops in patches between Yemassee and the Georgia line. Download offline maps. Wild hogs occasionally cross US-17 at dawn/dusk; reduce speed in rural sections.

• Family stop: The Salt Marsh Trail on Jekyll Island (easy 1-mile boardwalk).
• Pet-friendly: Savannah's Wormsloe Historic Site allows leashed dogs on the main avenue.

Fatigue management: Take a break every 90 minutes. The Rest Area at Mile 33 (GA) has a Splash Pad for cooling down. Pull off at Exit 87 in SC for boiled peanuts – a local energy snack.

Smooth asphalt dominates US-17 and I-95, with occasional construction near Savannah. Gas stations cluster every 20-30 miles; fill up in Ridgeland, SC (mile 85) for the best prices before Georgia's higher fuel taxes.

• Estimated fuel cost (mid-size sedan): $25–30 one-way.
• Tolls: None on this route.
• Rest areas: Three well-maintained stops on I-95 in SC and GA, each with picnic tables and pet areas.

Road quality is excellent from Charleston to the Georgia line, but I-95 south of Savannah has rough patches. Plan for a 15-minute buffer near Port Wentworth due to truck traffic.

The ACE Basin wetlands greet you 30 minutes south of Charleston. Look for alligators basking on canal banks near the Harleyville exit. Spanish moss drapes live oaks all the way to the Okatie River.

• Best natural stop: Savannah National Wildlife Refuge (mile 95) – 2-hour driving loop through freshwater marshes.
• UNESCO connection: Charleston's Historic District is part of a tentative UNESCO listing, but the route itself passes no designated sites.

Local commerce thrives in small towns like Walterboro, SC, where 'the Big Tree' (a 1,000-year-old oak) anchors a flea market. In Richmond Hill, GA, bakeries sell benne wafers - a sesame cookie with West African origins.
