So, you’re sitting in Atlanta traffic—maybe on the Downtown Connector or creeping along I-20—and the thought of salt air starts feeling less like a dream and more like a necessity. You want to know how far is Atlanta from Myrtle Beach South Carolina, and the short answer is about 360 miles.
But distance is a funny thing in the South.
If you just plug it into your GPS, you’ll see a number like five and a half or six hours. That's cute. It’s also rarely true. Between the Georgia DOT’s obsession with orange cones and the absolute slog that can happen once you hit the South Carolina state line, that 360-mile stretch can feel like a cross-country expedition or a breezy Sunday cruise depending entirely on your timing and your stomach for small-town speed traps.
The Reality of the Atlanta to Myrtle Beach South Carolina Distance
Most people assume it’s a straight shot. It isn't. You're basically cutting across the heart of the Carolinas, moving from the rolling hills of the Piedmont down to the Coastal Plain.
The most common route takes you east on I-20. You’ll pass through Augusta, which is roughly the halfway point and a great place to stop if you need a decent meal that isn't from a drive-thru window. From Atlanta to Augusta, it’s about 150 miles. You can usually knock that out in two and a half hours if you aren't leaving at 5:00 PM on a Friday. Honestly, if you leave Atlanta at 5:00 PM on a Friday, just turn around and go home. You’ve already lost.
Once you cross the Savannah River into South Carolina, the scenery changes. It gets flatter. The pine trees start looking a bit more bedraggled. You’ll stay on I-20 until you hit Florence. This is where the "real" travel begins.
The Florence Bottleneck
Florence is where the interstate ends for you. To get the rest of the way, you have to navigate US-501. This is the part of the trip that makes the Atlanta to Myrtle Beach South Carolina journey feel twice as long as it actually is.

US-501 is legendary. And not in a good way.
It’s the primary artery for everyone coming from the inland to the coast. You’ll pass through towns like Marion and Aynor. These places are charming, sure, but they are also full of stoplights and tourists who are just as frustrated as you are. In the peak of summer, that final 60-mile stretch from Florence to the beach can take two hours by itself. I’ve seen it happen. It’s a test of patience that requires a very specific playlist and maybe a bag of boiled peanuts from a roadside stand to survive.
Alternative Routes for the Impatient Traveler
If you hate 501—and most locals do—there are ways to shave off the stress, if not the actual mileage.
One popular "secret" is taking Highway 378 out of Turbeville. It’s a bit more rural, definitely more two-lane action, but it bypasses the nightmare of Florence. You’ll see more cows and fewer brake lights. It’s roughly the same distance, but psychologically, it feels faster because you’re actually moving.
Another option? Go down to I-16 toward Savannah and then cut up the coast on US-17. This adds significant mileage. You’re looking at closer to seven hours now. However, if you want to see Beaufort or Charleston on the way, it’s a stunning drive. It turns a "trip to the beach" into a "Lowcountry tour." Most people won't do this because they just want to get to the Grand Strand and put their toes in the sand, but it's worth mentioning for those who value the journey over the destination.
Why the Time Estimates Vary So Much
Let's look at the math, but keep it simple.

- Distance: ~360 miles.
- Optimal Time: 5 hours 45 minutes.
- Holiday Weekend Time: 7 to 8 hours.
- Middle of the Night Time: 5 hours 15 minutes (if you've got a lead foot).
The variation comes down to the "Grand Strand Factor." With over 60 miles of continuous beach, Myrtle Beach attracts roughly 20 million visitors a year. Most of them are driving. When you calculate how far is Atlanta from Myrtle Beach South Carolina, you have to account for the fact that you are joining a massive migration of people from all over the Southeast heading to the same neon-lit strip of pavement.
Stopping Points That Don't Suck
Since you're going to be in the car for a while, you might as well eat something better than a limp burger.
Augusta has some gems. If you have time to sit down, the downtown area near the riverwalk has some solid spots. But if you’re in a hurry, just grab something quick and keep pushing.
Columbia, South Carolina, is another major milestone. You’ll bypass the main city on I-20, but if you need a real break, the Riverbanks Zoo is nearby, though that’s a big commitment for a pit stop. Honestly, most travelers just stop at the Buc-ee's in Florence. It’s a rite of passage now. If you haven't experienced the chaos of 100 gas pumps and a wall of beef jerky, you haven't really driven through the South in the 2020s.
Fuel and Logistics
Expect to use about a tank and a half of gas if you're driving a standard sedan. SUVs will obviously thirsty-up a bit more. South Carolina gas prices are historically lower than Georgia’s, so if you can hold out until you cross the border, you might save enough for an extra scoop of ice cream at Peaches Corner.
What to Expect When You Finally Arrive
The transition from the pine forests of the interior to the coastal scrub is sudden. You’ll smell the salt before you see the water.

Once you hit the bypass (Hwy 17), you’re officially there. But remember, Myrtle Beach is huge. If you’re staying in North Myrtle, you’ve got another 20 minutes of driving ahead of you. If you’re down in Surfside or Garden City, you’ll be peeling off earlier.
The Atlanta to Myrtle Beach South Carolina trip is more than just a line on a map. It’s a transition from the frantic energy of a global hub to the kitschy, relaxed, and sometimes bizarre world of one of America’s favorite beach towns.
Surprising Facts About the Route
- The Elevation Drop: You start at about 1,000 feet above sea level in Atlanta and end at, well, zero. You’re literally driving down a giant ramp.
- Speed Traps: Small towns along US-501 and US-378 live for out-of-state plates. Keep it within five miles of the limit once the interstate ends. Seriously.
- The "Carolina Squat": Depending on when you go, you might see trucks with the front end jacked up and the back end dragging. It’s a local subculture thing. Just keep driving.
Making the Most of the Drive
To actually enjoy this trip, you need a strategy. Don't just wing it.
Start early. Like, 5:00 AM early. If you can get through Columbia before the morning rush, you’ve won half the battle. This puts you in Myrtle Beach by lunchtime, just in time to grab some Calabash-style seafood before the dinner crowds swarm the restaurants.
Also, download your maps. There are stretches between Columbia and Florence where cell service can get wonky, especially if you take the back roads. Having an offline map ensures you don't end up lost in a cotton field.
Actionable Takeaways for Your Road Trip
- Check the GDOT and SCDOT websites: Look for construction on I-20. They love closing lanes on weekends.
- Time your Florence arrival: Try to hit Florence before 2:00 PM to avoid the heaviest 501 traffic.
- Fuel up in South Carolina: Save your gas stops for the SC side of the line to take advantage of lower fuel taxes.
- Hydrate but be strategic: Restrooms are frequent on I-20 but get sparse once you hit the rural highways.
- Pack a physical map: Just in case your phone decides to overheat in the Southern sun.
When you're figuring out how far is Atlanta from Myrtle Beach South Carolina, don't just look at the miles. Look at the clock, look at the calendar, and plan for the Florence bottleneck. It’s a classic Southern road trip that requires a bit of grit and a lot of patience, but once you see that first glimpse of the Atlantic, the 360 miles of asphalt quickly fade into the background.
Before you head out, double-check your tire pressure. The heat on I-20 in the summer can be brutal on rubber, and the last thing you want is to be changing a flat on the shoulder near Conyers. Get your oil changed, pack the cooler, and hit the road. The beach is waiting.
