You're standing in the middle of the Vista in Columbia, humidity clinging to your shirt, and suddenly the idea of the Atlantic Ocean sounds like the only thing that matters. We've all been there. But before you throw the flip-flops in the trunk, you actually need to know the logistics. How far from Columbia to Myrtle Beach is it, really? If you look at a map, it’s a straight shot east, but South Carolina roads have a way of turning a "quick trip" into a multi-hour saga involving tractor trailers and small-town speed traps.
It’s about 150 miles.
Give or take a few, depending on whether you're starting in Lexington or closer to Fort Jackson. Most people will tell you it's a two-and-a-half-hour drive. They are usually lying, or they have a very heavy foot and a radar detector. In reality, you’re looking at roughly 2 hours and 45 minutes of actual windshield time if the gods of I-20 are smiling on you. If they aren't? Well, pack snacks.
The Main Vein: I-20 to US-501
Most GPS units are going to scream at you to take I-20 East. It makes sense. It’s a straight line. You jump on the interstate in Columbia, head toward Florence, and then the fun begins. This is the most common way to calculate how far from Columbia to Myrtle Beach, measuring in at approximately 152 miles from downtown to the Boardwalk.
The transition in Florence is where things get dicey. You hop off the big road and merge onto US-501. This is the legendary—or perhaps infamous—stretch of pavement that every South Carolinian knows by heart. It takes you through places like Marion and Galivants Ferry. Honestly, Galivants Ferry is beautiful, especially when the political stump meetings are happening, but the rest of the drive is a test of patience.
Why? Because 501 is a bottleneck. It’s the primary artery for everyone coming from the Upstate, North Carolina, and the Midlands. If it’s a Saturday in July? Forget it. That 150-mile trip will easily balloon into a four-hour ordeal.
The "Back Way" via US-378
Some old-school locals swear by US-378. You leave Columbia heading toward Sumter. It’s a different vibe. You’re trading the concrete expanse of I-20 for swampy lowlands and smaller towns.
This route is technically shorter in terms of raw mileage—closer to 145 miles—but it rarely saves you time. You’ll hit more stoplights. You’ll get stuck behind a logging truck in Turbeville. But if you hate the interstate grind, it’s a much more scenic way to see the "real" South Carolina. You pass through Conway before hitting the beach, which is a great place to stop for a sandwich if you aren't in a massive rush to hit the sand.

Why the Mileage Doesn't Always Matter
Distance is a funny thing in the South. 150 miles in Montana is a breeze. 150 miles between Columbia and the Grand Strand is a variable.
Traffic is the great equalizer. You have to account for the "Florence Factor." Since Florence is the midpoint, it’s where all the traffic from I-95 converges with the traffic from I-20. It creates a chaotic swirl of travelers all trying to squeeze onto the same two-lane sections of 501.
- Construction: There is almost always work being done on the 501 corridor.
- The Pee Dee River: Bridges can be a choke point, especially during hurricane season or heavy rains.
- Speed Zones: Places like Turbeville (on the 378 route) or McBee (if you're coming from further north) are legendary for their strict enforcement. Watch your speedometer.
Honestly, the distance is less about the miles and more about the timing. If you leave Columbia at 4:00 PM on a Friday, you’re asking for trouble. If you leave at 6:00 AM on a Tuesday? You’ll be eating a Po-Boy at the Sea Captain’s House before you even realize you left the Congaree behind.
Breaking Down the Neighborhoods
The distance changes based on where exactly you’re headed. Myrtle Beach isn’t just one spot; it’s a massive 60-mile stretch of coastline known as the Grand Strand.
If you’re going to North Myrtle Beach, you might want to consider taking SC-22 (the Veterans Highway) once you get close. It bypasses the 501 madness and drops you right near Briarcliffe Acres. This adds maybe 5 miles to the trip but can save you 20 minutes of sitting at red lights in Conway.
If your destination is Surfside Beach or Garden City, you’re looking at a slightly different approach. You’ll stay on 501 but hook south toward the bypass. It’s about 155 miles to get down to the pier at Garden City. It’s worth the extra few miles for the quieter atmosphere, at least in my opinion.
The Cost of the Trip
Let’s talk money. We aren't just calculating how far from Columbia to Myrtle Beach for the sake of geography. We're doing it for the wallet.

At 150 miles one way, you’re looking at a 300-mile round trip. If your car gets 25 miles per gallon, you’re burning 12 gallons of gas. With gas prices fluctuating, that’s usually a $40 to $50 bill just to get there and back. It’s one of the most affordable beach trips in the country for a capital city, which is why half of Columbia seems to relocate to Horry County every weekend.
What to Watch For on the Road
The drive is boring. I’ll say it. It’s flat. You’re going to see a lot of pine trees and a lot of billboards for fireworks stores and personal injury lawyers.
But there are some gems.
If you take the 378 route, you’ll pass through Sumter. The Swan Lake Iris Gardens are right there. It’s a weird, beautiful detour if you have an hour to kill. If you’re on I-20, your main landmarks are the Buc-ee’s in Florence.
Yes, the Buc-ee’s.
It has changed the math on the Columbia-to-Myrtle trip. It’s located right at the interchange of I-95 and I-20. It’s a massive convenience store with 100+ gas pumps. It’s become a mandatory pilgrimage site. Just be warned: stopping there will add 30 minutes to your trip because you’ll get mesmerized by the wall of beef jerky.
Real-World Travel Times
To give you a better sense of the reality, let's look at some "normal" windows.
- The Middle of the Night: 2 hours 15 minutes. (Don't do this, the deer on I-20 are the size of small horses).
- Weekday Morning: 2 hours 40 minutes.
- Summer Saturday: 3 hours 30 minutes to 4 hours.
- Holiday Weekends: Just stay home. Or leave at 4:00 AM.
Conway is the final hurdle. It’s a historic town, very charming, but the 501 bridge over the Waccamaw River is a bottleneck. Once you clear that bridge, you can practically smell the salt air. The tension in your shoulders starts to drop.
Myth-Busting the Shortcut
You’ll hear people talk about "secret" backroads through Hemmingway or Johnsonville.
Don't listen to them.
Unless there is a catastrophic accident on I-20, these routes usually take longer. They involve more turns, lower speed limits, and a high probability of getting stuck behind a tractor. Stick to the main roads unless you're intentionally trying to get lost in the lowcountry.
The distance between these two hubs is a rite of passage for South Carolinians. It’s the transition from the red clay of the Midlands to the sandy soil of the coast. It’s the move from the "Soda City" to the "Golf Capital of the World."

Essential Preparation for the 150-Mile Trek
Before you pull out of your driveway in Shandon or Irmo, do a quick check. South Carolina heat is no joke, and the stretch of I-20 between Columbia and Florence can feel like a desert if your A/C dies.
- Check your tire pressure. The heat on the asphalt during a July afternoon can cause blowouts if your tires are worn.
- Download your podcasts. There are some notorious cell service dead zones near the Lynches River.
- Waze is your friend. It’s the only way to know if there’s a speed trap in Marion or a wreck at the 501/544 split.
The trip is easy, but it requires respect. You're crossing half the state.
Actionable Steps for Your Trip
To make the most of the 150-mile journey, follow these specific strategies:
- Timing the Departure: Aim to leave Columbia either before 7:00 AM or after 7:00 PM if you are traveling during the peak summer season (June through August). This avoids the heavy "check-in" traffic that clogs 501 starting around noon.
- The Florence Bypass: If the GPS shows a deep red line on 501 North of Florence, consider taking SC-327. It loops around the main congestion and connects back to 501 further east. It's a localized "pro-tip" that can save fifteen minutes of idling.
- Fuel Strategy: Gas is almost always cheaper in Florence or the outskirts of Conway than it is directly in Myrtle Beach or downtown Columbia. Fill up at the Buc-ee's or the surrounding stations to save a few bucks before hitting the tourist-priced pumps at the coast.
- Destination-Specific Routing: Use SC-22 for North Myrtle Beach/Little River and SC-31 for anything toward Socastee or Murrells Inlet. 501 is the "front door," but these highways are the "side doors" that bypass the stoplight-heavy business districts.
Knowing how far from Columbia to Myrtle Beach is just the start. Managing the 150 miles with a bit of strategy turns a grueling drive into a smooth transition to vacation mode. Pack the cooler, watch your speed in the small towns, and you'll be on the sand in under three hours.
