If you’re staring at a map of the Lowcountry, the distance Charleston to Savannah looks like a straight shot down the coast. It’s about 107 miles. That’s the official number if you take the most direct route via US-17 and I-95. Most people assume they’ll just zip down the highway in two hours and be done with it.
They're usually wrong.
Honestly, the "distance" between these two Southern staples isn't just about mileage; it's about the psychological shift from the refined, steeple-lined streets of Charleston to the moody, moss-draped squares of Savannah. You've got options. You could hammer it out on the interstate, or you could take the "scenic" route, which is actually a series of winding backroads that make the distance feel like a journey through another century. I've done this drive more times than I can count, and the biggest mistake travelers make is trusting the GPS blindly without understanding how the salt marshes and bridge closures actually dictate your day.
Breaking Down the Distance Charleston to Savannah by Route
Let’s talk logistics. If you jump on I-17 South out of Charleston, you’re eventually going to merge onto I-95 South at Point South. That’s the "fast" way. It’s roughly 107 to 110 miles depending on where in the historic districts you start. On a Tuesday at 10:00 AM? You’re looking at about two hours.
On a Friday at 4:30 PM? Forget it.
Traffic around the Ravenel Bridge or the bottlenecking near Hardeeville can turn that two-hour sprint into a three-hour slog. Then there's the alternate route. Some people prefer sticking to US-17 the whole way. It’s slightly more miles, maybe 115, but it takes you through places like Gardens Corner. It’s slower. There are stoplights. But you get to see the ACE Basin, which is basically 350,000 acres of protected wetlands. It's beautiful. It's also where you'll likely see a sunbathing alligator if you're looking closely enough at the canals.
The I-95 "Fast" Route
This is the route for people who just want to get there. You’ll spend a good chunk of time on I-95, which, let's be real, is one of the most boring stretches of asphalt in America. It’s flat. It’s lined with billboards for fireworks and personal injury lawyers. The distance Charleston to Savannah via I-95 is about 108 miles. You’ll pass through Walterboro. Not much happens there unless you need gas or a quick bite at a chain restaurant.

The US-17 Scenic Route
This is the "real" Lowcountry. It adds maybe 15 minutes to your trip, but it feels more authentic. You’ll pass the Old Sheldon Church Ruins. If you have an extra twenty minutes, pull over there. The ruins were burned by the British during the Revolutionary War and then again by Sherman’s army during the Civil War. Standing among those brick columns makes the distance Charleston to Savannah feel like a trek through a history book.
Why the Mileage Doesn't Tell the Whole Story
Google Maps will tell you one thing, but the Lowcountry tells you another. We have something called "King Tides." When the moon is right and the tide is high, coastal roads flood. I’ve seen parts of the route near the Savannah River crossing get sketchy during heavy rain or high tide cycles.
Also, consider the bridges.
The Talmadge Memorial Bridge in Savannah is a beast. Coming into the city from the north, you’ll rise high over the shipping channel. It’s a spectacular view of the container ships, but if there’s a wreck on that bridge, your "107-mile trip" is effectively paused indefinitely. There’s no easy way around it once you’re on that approach.
What most people get wrong about the drive
People think these two cities are "sister cities." They aren't. They’re rivals. Charleston is "The Holy City," polished and increasingly expensive. Savannah is "The Hostess City," a bit more bohemian, a bit more "haunted," and significantly more laid back about its open-container laws. Crossing the distance Charleston to Savannah is like moving from a formal dinner party to a backyard oyster roast.

If you're making the trip, you’re passing right by Beaufort, South Carolina. It’s about midway. It's roughly 70 miles from Charleston. Beaufort is where they filmed Forrest Gump and The Great Santini. The downtown waterfront is worth a 30-minute walk. If you’re hungry, find a spot that serves authentic Frogmore Stew. It’s not actually made of frogs—it’s shrimp, corn, sausage, and potatoes.
- Gardens Corner: This is where US-17 and US-21 meet. The oak trees here are massive. They form a literal tunnel over the road.
- The Carolina Cider Company: Located right on the highway. Grab a jug of local cider or some pickled okra. It’s a cliché for a reason—it’s good.
- Pocotaligo: It’s a tiny spot, but it’s a fun word to say and marks the point where you really start heading into the deep South Carolina woods before hitting the Georgia border.
Fact-Checking the "Shortcuts"
You might hear locals talk about taking backroads through the islands. Unless you are specifically trying to visit Hilton Head, don't do it. Adding Hilton Head to your trip from Charleston to Savannah adds significant distance. You’ll get stuck in the traffic on US-278, which is a nightmare during tourist season. Stick to the main arteries unless you have a full day to kill.
The actual border between the states is the Savannah River. Once you cross that bridge, you’re practically in the historic district. It’s one of the few drives where the transition from "wilderness" to "urban center" happens in a matter of seconds.
Traveling by Bus or Train
Not everyone wants to drive. Amtrak runs the Palmetto and the Silver Meteor lines between Charleston and Savannah. The distance is the same, but the vibe is different. The train station in Charleston is actually in North Charleston, which is about a 15-minute Uber from the peninsula. In Savannah, the station is also a bit outside the main historic area.
The train ride usually takes about 1 hour and 45 minutes. It’s comfortable. You see parts of the marsh that the highway doesn't touch. However, the schedules can be wonky. If the train is coming from New York or Miami, it can be delayed by hours. I wouldn't rely on it for a tight schedule.
Greyhound and Southeastern Stages also run buses. It’s cheap—sometimes twenty bucks—but it’s a three-hour trip because of the stops. Honestly, if you can drive or rent a car, do it. The freedom to stop for boiled peanuts on the side of the road is half the point of being in the South.

Actionable Advice for Your Trip
To make the most of the distance Charleston to Savannah, you need a plan that accounts for more than just miles.
Check the SCDOT (South Carolina Department of Transportation) website before you leave. They are constantly doing construction on I-95 near the Georgia border. Sometimes they drop it down to one lane, and that 107-mile trip suddenly takes four hours.
Time your departure. Leave Charleston by 9:00 AM to beat the morning rush, and you'll arrive in Savannah just in time for a late lunch at Mrs. Wilkes’ Dining Room (if you're lucky enough to get a seat).
If you're driving at night, watch for deer. This stretch of the Lowcountry is thick with them. They aren't afraid of your headlights. Seriously.
Lastly, don't rely solely on your phone. Cell service can get spotty in the ACE Basin. Download your maps for offline use before you leave the hotel. It’s a short distance, but the marshes are vast, and getting turned around on a dirt road in rural South Carolina is a specific kind of stress you don't want on your vacation.
Pack some water, grab a bag of pecans from a roadside stand, and enjoy the transition from one historic powerhouse to the other. The distance Charleston to Savannah is more than a number; it's the gateway to the Deep South.
Next Steps for Your Lowcountry Road Trip:
- Verify the Tide: If taking coastal backroads, check for any "King Tide" warnings that might cause localized flooding on US-17.
- Download Offline Maps: Save the Google Maps area for the 100-mile corridor between Charleston and Savannah to avoid dead zones in the ACE Basin.
- Check I-95 Construction: Use the 511SC app to see real-time lane closures near the Georgia/South Carolina border.
- Schedule a Midway Break: Mark Beaufort, SC, as a waypoint to break up the drive and see the Beaufort River waterfront.
