Let’s be real. If you’re sitting in Columbia and staring at a GPS, you probably just want to know how long it’s going to take before your toes are in the sand. You’ve likely seen the raw numbers. The distance Columbia SC to Myrtle Beach is roughly 150 miles.
Give or take.
Depending on whether you’re starting from the Harbison area or leaving out of Shandon, that number shifts. Most people assume it’s a straight shot. It isn't. South Carolina’s geography is a bit of a tease like that. You aren't just driving; you're navigating a transition from the rolling Red Hills of the Midlands down into the flat, pine-heavy Pee Dee and finally hitting the Grand Strand.
It takes about 2 hours and 45 minutes on a perfect day. But honestly? Perfection is rare on US-501.
Why the Distance Columbia SC to Myrtle Beach Feels Longer Than It Is
Most maps will tell you the shortest path is about 142 miles if you take US-378 E. Some people swear by I-20 E to I-95. The truth is, the "distance" isn't the problem. It’s the infrastructure.
You’re basically moving through a series of small towns that time—and the Department of Transportation—occasionally forget. When you’re driving through Sumter or Turbeville, that 150-mile stretch starts to feel like a cross-country odyssey.
The speed limits are a rollercoaster. One minute you're cruising at 60 mph, and the next, you're slamming on the brakes because the limit dropped to 35 mph in a town with one stoplight and a very active police cruiser tucked behind a live oak tree. Turbeville is legendary for this. Seriously. Don't speed there.
The Three Main Routes Most Locals Argue About
There isn't one "correct" way to handle the distance Columbia SC to Myrtle Beach. Everyone has a "secret" way.

The Classic US-378 Route: This is the most direct shot. It’s about 145 miles. You go through Sumter. You see a lot of cotton fields. It’s two lanes in sections, which means if you get stuck behind a tractor or a log truck, your arrival time just plummeted.
The I-20 to I-95 North Pivot: This is for the people who hate stoplights. You take I-20 East toward Florence, hop on I-95 North for a tiny bit, and then grab US-501. It adds mileage—usually pushing you closer to 160 miles—but you’re maintaining 70 mph for a larger chunk of the trip.
The SC-261 "Back Way": Honestly, this is only for people who really enjoy the scenery of the Lowcountry. It’s slower. It’s winding. But if you want to avoid the 501 nightmare near Conway, it’s an option.
Traffic: The Variable No One Accounts For
Check the calendar before you leave. If it’s a Friday in July, that 2 hour and 45 minute estimate is a lie. A total fantasy.
The bottleneck at Conway is where dreams go to die. As you approach the end of the distance Columbia SC to Myrtle Beach, US-501 narrows and the traffic from North Carolina merges in. It’s a mess. I’ve seen that last 10-mile stretch take 45 minutes on a holiday weekend.
If you can, leave Columbia at 6:00 AM. Or wait until 7:00 PM. Anything in between during tourist season is a gamble with your sanity.
Pit Stops That Make the Drive Worth It
Since you're covering over 140 miles of South Carolina blacktop, you might as well eat well. You aren't just traversing distance; you're moving through the heart of BBQ country.

In Sumter, you’ve got places like McCabe’s (though check their hours, they're old-school). Once you get closer to Hemingway or the outskirts of the route, the vinegar-based sauce starts to take over. This is a crucial cultural shift. Columbia is mustard-base territory. Myrtle Beach is a melting pot. But that middle ground? That’s where the real pits are.
Watch Out for the Speed Traps
It would be irresponsible not to mention the law enforcement presence on the way to the coast. The distance Columbia SC to Myrtle Beach is a major revenue corridor for several small municipalities.
- Turbeville: Mentioned it before, mentioning it again. It’s a 35 mph zone that means exactly 35.
- Sumter County: The highway patrol loves the long, flat stretches of 378.
- Conway: As the speed drops entering the city limits, keep your eyes peeled.
Beyond the Odometer: What to Know Before You Go
A lot of people ask if it’s better to fly. From Columbia (CAE) to Myrtle Beach (MYR)? No. By the time you deal with TSA, the layover (because there are rarely direct flights between these two specific cities), and renting a car, you could have driven the distance three times over.
This is a road trip. It’s a rite of passage for South Carolinians.
The terrain changes subtly. You'll notice the soil turning from that thick, red Carolina clay to a pale, sandy gray. The trees change from hardwoods to scrub oaks and towering loblolly pines. You can actually smell the salt in the air once you cross the bridge over the Intracoastal Waterway in Myrtle Beach.
Technical Stats for the Data Nerds
If we're talking straight-line distance—"as the crow flies"—it's only about 120 miles. But unless you have a Cessna, that doesn't help you much.
For those driving EVs, the distance Columbia SC to Myrtle Beach is well within the range of a Tesla Model 3 or a Chevy Bolt, but charging in the middle of the state is still a bit spotty. You'll find Superchargers in Columbia and Florence, but don't expect to find a high-speed charger in the middle of a peanut field in Lynchburg. Plan accordingly.

Fuel prices also fluctuate. Usually, gas is a few cents cheaper in the Columbia suburbs than it is once you get within five miles of the ocean. Fill up before you leave the 803 area code.
Navigating the Conway Bypass
One of the biggest mistakes people make when finishing the distance Columbia SC to Myrtle Beach is staying on 501 all the way.
Look for SC-22 (the Veterans Highway). It’s a bypass. It’s glorious. It’s a controlled-access highway that dumps you out on the north end of Myrtle Beach near Briarcliffe Acres. If your hotel or condo is in North Myrtle, taking the bypass can save you 20 minutes of stop-and-go misery.
If you're heading to the South Strand—Surfside or Garden City—stay on 501 or look for the 544 turn-off.
Practical Steps for Your Trip
To make the most of the drive, don't just mindlessly follow the blue line on your phone. South Carolina roads are quirky.
- Download your maps: There are dead zones on US-378 where 5G goes to hide. If your GPS isn't cached, you might miss a turn-off in the woods.
- Check the SCDOT '511' app: This is the only way to know if a tractor-trailer has turned over near Florence, which happens more than you'd think.
- Pack a physical map: Kinda old school, right? But if your phone dies and your charger port acts up, you'll be glad you have a paper backup of the state's secondary roads.
- Time your Conway arrival: Use Waze to check the "reach by" time. If it shows a massive red cluster near the Waccamaw River, take the back roads through Galivants Ferry.
The distance Columbia SC to Myrtle Beach is more than a number on a screen. It’s a transition from the capital city’s bustle to the coastal rhythm. Keep your cruise control reasonable, grab a sweet tea in Sumter, and take the SC-22 bypass if you’re heading north. You'll save time, avoid a ticket, and actually enjoy the ride.
