St. Augustine to Beaufort: A Coastal Drive Through History and Nature

St. Augustine’s Castillo de San Marcos, built in 1672, is the oldest masonry fort in the continental United States. From its coquina walls, you’ll head north on US-1, a historic highway that parallels the Intracoastal Waterway for much of the 174-mile journey to Beaufort’s moss-draped oaks. The drive takes about 3 hours without stops, but you’ll want to linger on barrier islands and in low-country towns.

This route crosses ecosystems from maritime hammocks to salt marshes, passing through Georgia’s Golden Isles and South Carolina’s sea islands. King’s Highway (US-17) offers a slower alternative, but US-1 and I-95 are the main arteries. Expect no tolls and mild traffic except near Jacksonville’s sprawl.

Key coordinates: St. Augustine (29.9013° N, 81.3124° W) to Beaufort (32.4316° N, 80.6696° W). The natural midpoint is Brunswick, GA, at the junction of US-17 and I-95. For a complete tool to plan custom stops, check out how to find the best stops and hidden gems between cities.

I-95 has a high volume of semi-trailers; maintain a 3-second following distance. US-1 and US-17 have frequent intersections and slower speed limits (45-55 mph). Watch for deer at dawn and dusk, especially in the Okefenokee area. No construction zones expected on a typical weekend.

For families, the St. Augustine Alligator Farm Zoological Park is a world-class reptile exhibit. In Brunswick, the 1898 oaks of Lover’s Oak (100 Central Ave) provide a quick photo op. Beaufort’s Henry C. Chambers Waterfront Park has a playground and splash pad.

• Rest stops: Georgia’s rest area at mile 42 (northbound) has clean restrooms and vending machines.
• Fatigue zones: Long straight stretches on I-95 between Darien and Savannah; take a break at the Midway exit (mile 76) for fast food.
• Pet-friendly stops: St. Augustine’s Dog Beach (3500 Coastal Hwy) and Beaufort’s Sands Beach (off Brickyard Point Road) allow off-leash dogs.

Hidden off-route spots: Hofwyl-Broadfield Plantation (GA), 5 miles off I-95 exit 42, offers a glimpse into 19th-century rice plantations. In SC, Hunting Island State Park (15 minutes from Beaufort) has a historic lighthouse and undeveloped beach—nature’s best in the Lowcountry.

Culinary highlights: B&J’s Steak and Seafood in Darien (GA) serves fried shrimp on US-17. In Beaufort, Foolish Frog (1408 Boundary St) offers low-country boil and craft beer. Georgia peaches are in season June-August; find stands on US-17 north of Brunswick.

Fatigue management: Stop every 2 hours. The best break points are the Georgia Visitor Center (northbound) and the rest area at mile 33 in South Carolina. Caffeine can be found at Starbucks in Brunswick and Beaufort.

Fuel stations cluster around exits every 10-15 miles on I-95, but US-1 has longer gaps—particularly between Folkston, GA and Brunswick. Fill up in St. Augustine or Jacksonville before crossing into Georgia. Gas prices trend lower in Georgia (about $0.20 less per gallon than Florida).

The route crosses the St. Johns River in Jacksonville via the I-95 Fuller Warren Bridge. Watch for congestion during morning and evening commutes. South of Brunswick, US-17 hugs the coast with 55 mph zones, offering slower but more scenic travel.

• Rest areas: Florida Welcome Center (north of Yulee), Georgia Visitor Center (exit 1 on I-95).
• Towing services: AAA coverage along entire route; cell signal generally strong.
• Road quality: I-95 is well-paved; US-17 has some rough patches near Darien, GA.

Electric vehicle charging stations are available at Electrify America in St. Augustine (2000 State Road 16) and Tesla Superchargers in Brunswick (1401 Glynn Parkway). Plan for a 30-minute charge stop. The route has no toll roads.

For those towing a trailer, avoid the narrow streets of historic St. Augustine downtown. Use the parking garage at 1 Cordova Street. Beaufort’s historic district has limited parking; use the city lot at 1001 Bay St.

Leaving St. Augustine, you’ll cross the Tolomato River and enter the Guana Tolomato Matanzas National Estuarine Research Reserve. This 73,000-acre preserve protects salt marshes and maritime forest. Stop at the trailhead for a short boardwalk hike (0.5 miles) overlooking the marsh.

Further north, Amelia Island’s Fort Clinch State Park showcases a 19th-century fort plus pristine beaches. The park entrance fee is $6 per vehicle. Listen for the call of painted buntings among the live oaks.

• Natural landmarks: Little Satilla River (GA), Sapelo Sound (GA), Broad River (SC).
• Best overlook: Jekyll Island’s Driftwood Beach (GA)—a surreal landscape of fallen trees.
• Local commerce: Brunswick’s historic downtown offers antique shops and the Brunswick Old Town farmers market (Saturdays).

The route passes through Georgia’s Gullah-Geechee corridor, a cultural heritage area spanning from Sapelo Island to Beaufort. In Darien, GA, visit the Sapelo Island Visitors Center to learn about the Gullah-Geechee people’s rice cultivation and basket weaving traditions.

Beaufort’s National Historic Landmark District contains antebellum mansions along Bay Street. The Beaufort History Museum at 713 Craven Street details the area’s role in the Civil War and Reconstruction. Local craftspeople sell sweetgrass baskets—a Gullah tradition—at the Port Royal Farmers Market.
