Hilton Head Island to New Bern: Coastal Carolina Road Trip Guide

The route from Hilton Head Island, SC to New Bern, NC traces nearly 350 miles of the Atlantic coastal plain, roughly 5.5 to 6.5 hours of drive time depending on traffic and stops. Unlike the monotonous Interstate 95 corridor, this journey follows US-17 and State Road 170—roads that wind through centuries-old live oaks, past tidal marshes, and into historic port towns. A little-known fact: the section through Beaufort County, SC, uses the same alignment as the original King's Highway, a colonial postal route established in the 1730s. This highway once connected Charleston to Boston, and drivers today still pass under the same sprawling oak canopies that shaded mail carriers on horseback.

Understanding the logistics ensures a smooth trip. The most direct path is via US-278 east to I-95 north, then US-17 north through Charleston, SC, and into NC. However, a more scenic alternative is SC-170 from Hardeeville to Beaufort, then US-21 to Charleston, avoiding I-95's monotony. Fuel costs average $45-$60 for a sedan; gas stations are abundant near towns but sparse on rural stretches—plan to fill up in Hilton Head, Beaufort, or Charleston. Tolls are minimal; only a few bridges like the Ravenel Bridge in Charleston require a small fee ($1.50). Rest areas occur every 30-40 miles on US-17, but most are unstaffed. A table of key milestones helps plan breaks:
