You're standing in your kitchen in Atlanta, probably somewhere near the Connector or maybe tucked away in Decatur, and the humidity is finally starting to feel less like a "southern charm" thing and more like a "I need to submerge myself in salt water" thing. You want the beach. Specifically, you want the Grand Strand. But before you toss the cooler in the trunk, you're asking the big question: how far is Myrtle Beach from Atlanta?
The short answer is about 360 miles. If you're a robot driving a car in a vacuum with zero bathroom breaks and a bladder made of steel, you could theoretically make it in five and a half hours.
But you aren't a robot. You're a person who probably lives in a city where a trip to the grocery store takes forty minutes.
The Reality of the Georgia-South Carolina Trek
Most people looking at a map see a straight shot. They see I-20 East, a quick veer onto some state roads, and boom—ocean. In reality, the distance between these two hubs is as much about psychological endurance as it is about odometer readings. Honestly, your experience depends entirely on when you pull out of your driveway.
If you leave at 4:00 AM? You’re a hero. You’ll hit Augusta before the sun really starts punishing your windshield. If you leave at 4:00 PM on a Friday? Godspeed. You’ll spend the first ninety minutes of your vacation just trying to see the "Welcome to South Carolina" sign.
The mileage usually clocks in between 355 and 370 miles depending on if you're coming from Marietta or South Fulton. Generally, the most efficient route takes you down I-20 East through Augusta, then hooks you onto US-76 or US-378 toward the coast. It’s a transition from the rolling hills of the Piedmont to the flat, pine-heavy landscape of the Lowcountry.
Why the "Six Hour" Estimate is Kinda a Lie
Google Maps is an optimist. It assumes everyone drives five miles over the limit and never hits a red light in Florence, South Carolina. When you calculate how far is Myrtle Beach from Atlanta, you have to factor in the "Florence Factor."

Florence is where the interstate ends and the "real" South Carolina begins. It's the bottleneck. You get off the big highway and onto smaller roads where the speed limits fluctuate like the stock market. You’ll pass peach stands, fireworks warehouses, and about a dozen places claiming to have the best BBQ in the South.
You’ll stop. Of course you will.
By the time you factor in a stop at Buc-ee’s (the one in Florence is basically a rite of passage for Atlanta travelers now), a quick stretch, and the inevitable traffic crawl as you enter Myrtle Beach city limits, you’re looking at six and a half to seven hours.
Route Options: The I-20 Grind vs. The Backroads
Most GPS systems are going to shove you onto I-20. It’s efficient. It’s boring. It’s mostly just trees and the occasional billboard for a personal injury attorney.
But there’s a second way.
Some folks prefer taking I-85 North toward Greenville and then cutting across. This is longer. Way longer. Don’t do this unless you have a specific reason to visit Spartanburg or you just really love the smell of BMW factories. Stick to the I-20 route.

Once you hit Columbia, you have a choice. You can stay on I-20 until it dies out or cut off earlier. Some locals swear by US-378 because it feels more "vacation-y." It’s a two-lane vibe. You see the small towns. You see the old tobacco barns. It makes the distance to Myrtle Beach feel more significant, like you’re actually traveling somewhere, rather than just teleporting from one suburban sprawl to another.
The Augusta Pit Stop
If you’re doing the drive properly, Augusta is your halfway mark. It’s roughly 150 miles from downtown Atlanta. This is the "point of no return." If you forgot your swimsuit, buy it here, because once you pass Augusta, the retail options get a little more... rural.
- Pro Tip: If you have time, stop at the Augusta Canal. It’s a weirdly beautiful spot to walk for ten minutes just to keep your legs from cramping up before the second leg of the trip.
Surviving the Last 60 Miles
The last hour is the hardest. You can smell the salt air, or at least you think you can, but you’re stuck behind a log truck on a two-lane highway. This is where the Myrtle Beach distance from Atlanta feels the longest.
You’ll pass through places like Conway. Conway is lovely, but it’s also the gatekeeper. Traffic here can be a nightmare during peak summer Saturdays (check-in day). If you arrive between 2:00 PM and 5:00 PM, expect to add thirty minutes to your total travel time just to cross the bridge over the Intracoastal Waterway.
The Cost of the Trip: Gas and Snacks
Let’s talk money. We aren't in 2019 anymore. Gas prices in South Carolina are usually cheaper than in Georgia, thanks to lower state taxes.
If your car gets 25 miles per gallon, you’re looking at about 15 gallons of gas one way. At $3.20 a gallon, that’s roughly $48. Round trip, you’re under a hundred bucks for fuel. That’s significantly cheaper than flying into MYR (Myrtle Beach International), which often involves a layover in Charlotte or a pricey direct flight on Delta.

Plus, you need your car once you get there. Myrtle Beach isn't exactly a walkable city unless you stay strictly on the Boardwalk, and even then, you’ll want to hit Murrells Inlet for dinner.
When to Make the Drive
Seasonality matters.
- Summer (June–August): This is the peak. Expect every person in the Southeast to be on the road with you. The drive will take longer.
- Fall (September–October): Honestly the best time. The water is still warm, the crowds are gone, and I-20 is clear.
- Spring Break: High traffic, lots of police presence on the smaller highways. Watch your speed in those small SC towns; they take their 35 mph zones very seriously.
What Most People Get Wrong About the Distance
The biggest misconception is that Myrtle Beach is "right there." It's not. It's a journey. Unlike going to Lake Lanier or even driving down to Savannah, the trek to the Grand Strand requires a bit of mental prep.
People also underestimate the boredom. The stretch of South Carolina between Columbia and the coast is famously flat. There isn't much to look at. This is the time to catch up on that 12-part true crime podcast you’ve been saving.
Beyond the Map: Making the Miles Count
Since you're committed to the drive, make it better. Don't just eat McDonald's at a rest stop. If you're hungry around Columbia, get some "Carolina Gold" BBQ. It's mustard-based, it's yellow, and it's completely different from the sweet tomato stuff you find in Georgia. It’s part of the experience.
When you finally see those iconic "Gay Dolphin" or "Putter’s Paradise" signs, you’ll realize the 360 miles were worth it. The Atlantic looks different than the Gulf. It’s bigger, wilder, and the sand actually feels like sand.
Actionable Next Steps for Your Trip
Stop over-planning and start prepping the car.
- Check your tires: I-20 can get incredibly hot in the summer, and blowouts are no joke when you're 50 miles from the nearest town.
- Download your maps: Cell service can get spotty on the backroads of South Carolina once you leave the interstate corridor.
- Time your exit: Leave Atlanta by 5:30 AM or wait until after 7:00 PM. Anything in between is just asking for a headache.
- Budget for the bridge: When you hit the bridge in Conway, stay in the left lane if you're heading to North Myrtle, and the right lane if you're going to the South end/Surfside.
The distance from Atlanta to Myrtle Beach is a manageable day-trip length, but it's a full-day commitment if you want to arrive without being completely exhausted. Pack the sunscreen in the cabin, not the trunk. You'll want it the second you step out of the car.
