Coastal Drive: Beaufort NC to Tybee Island GA Guide

Beaufort, North Carolina, is one of the few remaining authentic coastal towns where the 18th-century street grid still dictates modern navigation. The 275-mile route to Tybee Island, Georgia follows US-70, US-17, and a final stretch on GA-80. Expect 5.5 hours of pure driving, but the journey demands at least two full days to absorb its layered history and ecology.

This corridor traces the Intracoastal Waterway’s edge, passing through the Croatan National Forest, the Cape Fear region, and the salt marshes of the Lowcountry. It is a drive of profound contrasts: from the pirate-haunted waters of Beaufort to the Victorian languor of Tybee’s lighthouse.

The below table summarizes critical distances and times for planning.

Begin on US-70 west from Beaufort, crossing the Newport River and soon merging onto US-17 south near Havelock. US-17 is a classic two-lane highway through pine savannas, but beware of logging trucks. The key refueling points are at the US-70/US-17 junction in Havelock (mile 20) and again in Jacksonville (mile 50).

South of Wilmington, the route joins I-140 bypass to avoid downtown, then drops back to US-17 through the Carolina Beach State Park area. The section through Myrtle Beach is notorious for traffic; plan for an extra 30 minutes. After Georgetown, SC, US-17 becomes a scenic coastal highway with numerous swing bridges—South Carolina’s Highway 17 Business through Mount Pleasant offers the best waterfront views.

The final 20 miles from Savannah to Tybee Island require crossing the Bull River on GA-80, a two-lane causeway with tidal creeks on both sides. This stretch is prone to flooding during king tides, so check tide charts if traveling in fall.

• Best fuel stop: Havelock (Chevron at 209 US-70) has diesel and ethanol-free gas.
• Worst congestion: Surfside Beach, SC (US-17, 2-4 PM).
• Key highway: US-17 provides the most direct route but consider US-21 for a slower coastal detour.

US-17 through South Carolina has narrow shoulders and frequent wildlife crossings (deer and wild hogs). Night driving is strongly discouraged between Georgetown and Charleston due to low lighting and curves. Use the rest area at the Santee River (mile 240) for a safe lighting break.

For families, the North Carolina Aquarium at Fort Fisher (mile 100) has touch tanks and a butterfly house, while Myrtle Beach’s Broadway at the Beach offers amusement rides. Pet-friendly stops include the Isle of Palms County Park (SC), where dogs can run on-leash before the Tybee Island pier.

Fatigue management: The longest monotonous stretch is the 50-mile segment from Myrtle Beach to Georgetown. Plan a stop at the Hobcaw Barony Discovery Center (mile 220) to stretch legs on a 1-mile boardwalk. For off-route hidden gems, explore how to find the best stops and hidden gems between cities.

• Rest zone: Williamsburg County Rest Area (I-95, mile 270) has vending machines and clean restrooms.
• Safety note: GA-80 into Tybee has a 35 mph speed limit and pedestrian crossings near the pier.

The Croatan National Forest offers the first major natural attraction. Stop at the Cedar Point Tideland Trail (mile 15) for a boardwalk through brackish marsh where you can spot river otters. Further south, the town of Swansboro has a historic waterfront with shrimp boats and two excellent seafood markets.

UNESCO World Heritage Sites are not directly on this route, but the Charleston Historic District (a World Heritage tentative site) and the Gullah Geechee Cultural Heritage Corridor offer deep cultural immersion. In Charleston, the Old Slave Mart Museum and Charleston City Market embody the region’s complex history.

• Natural stop: Huntington Beach State Park (mile 180) has a nature center and alligators.
• Commerce: Farmers markets in Georgetown (Pavilion, Saturday 8-1) sell boiled peanuts and benne wafers.
• Unique detour: The Angel Oak Tree on Johns Island is a 400-year-old live oak, 10 minutes off US-17 via SC-700.
