9 South Carolina Coastal Towns Getting Too Crowded to Love

The line for the beach path forms before the coffee shop unlocks its door.

That’s a summer Saturday on the South Carolina coast now.

Everyone came for the charm, and then everyone stayed.

These are the South Carolina coastal towns getting too crowded to love.

1. Mount Pleasant

Mount Pleasant is still a town on paper.

It counted 91,244 residents at the 2020 census, and the count has kept rising since.

The population jumped 34 percent between 2010 and 2020, one of the fastest runs of any municipality in the state.

Shem Creek’s shrimp boats now share the water with paddleboard tours, and the restaurant docks fill by late morning.

Coleman Boulevard carries beach traffic, school traffic, and construction trucks at the same time.

The old village charm survives, but you’ll wait through three light cycles to see it.

Locals time errands around Ravenel Bridge traffic the way other people time tides.

2. Bluffton

Bluffton covered about one square mile in the late 1980s.

Today, the town sprawls across more than 50, and its population grew over 120% in a decade to 27,716 people at the 2020 census.

Old Town still has its oaks, its May River views, and its oyster roasts.

But new subdivisions keep landing along the Highway 278 corridor, and longtime Blufftonians keep learning new stoplights.

The secret of a slow afternoon on the May River stopped being a secret years ago.

3. Hilton Head Island

About 37,700 people live on Hilton Head Island year-round.

Roughly 2.5 million visitors join them every year.

The town planned for bike paths and tree cover, not for the backups that now stack up on Highway 278 at the bridges.

Coligny Beach parking fills by mid-morning in June.

Sea Pines still delivers the shaded, planned calm that made the island famous.

Getting there in July tests the calm before you find it.

Residents learn the back way to everything, and even the back way has a season.

4. Sullivan’s Island

Sullivan’s Island is Charleston’s closest beach town, and every Charlestonian knows it.

Street parking runs out by breakfast on summer weekends.

Park with a tire still on the pavement, and the police department writes the ticket fast.

Town council has even weighed opening an employee parking lot to the public just to handle the summer overflow.

You can measure the crowds by the wait for a table at Poe’s Tavern.

5. Pawleys Island

Only about 130 people live in the town of Pawleys Island.

The town incorporated in 1985 largely to keep development out, and the zoning still holds the line on building height.

Thousands cross the two causeways anyway on summer Saturdays for the beach, the crabbing docks, and the hammock shops just inland.

Public parking amounts to a handful of spots near each beach access.

Do the math on a July weekend, and you’ll see why arriving after 9 a.m. means circling.

6. Surfside Beach

Surfside Beach goes by "The Family Beach," two miles of sand just south of Myrtle Beach's high-rises.

The town also declared itself the world's first autism-friendly travel destination, and families noticed.

Summer rentals book out by spring now.

Golf carts stack up near the pier at sunset, and the two miles of sand feel shorter every year.

Surfside Beach is still calmer than Myrtle Beach, and the gap narrows every summer.

7. Edisto Beach

Edisto Beach runs on one road in and one road out, Highway 174.

The town's census count went from 414 in 2010 to 1,033 in 2020, and the vacation crowd grew right along with it.

There's no chain hotel on the island and hardly a franchise sign anywhere.

That's exactly why everyone wants in.

Campsites at Edisto Beach State Park book months ahead, and Highway 174 backs up on summer Saturdays.

8. Kiawah Island

Kiawah Island counted 2,013 residents at the 2020 census.

Resort guests outnumber them many times over on a summer day.

Most of the island sits behind a gate, so day visitors funnel into Beachwalker Park on the west end.

Its parking area fills early on summer weekends, and the county turns cars away once it does.

Championship golf made Kiawah Island famous, and famous beaches don't stay empty.

9. Port Royal

Port Royal kept its shrimp docks and its low-slung Paris Avenue while Beaufort County boomed around it.

South Carolina's population boom is spilling into its smaller towns, and in Port Royal, the proof is a skyline of new rooftops.

The Sands and its boneyard beach used to feel like a local secret at low tide.

Now the parking area fills on weekends.

New apartments keep rising near the old village, and weekend visitors keep finding the shrimp docks.

What's Driving the Crush

The Census Bureau says South Carolina grew 1.5% between July 2024 and July 2025, the fastest rate in the country.

That's 79,958 more people in a single year.

Of those, 66,622 came from other states, and the coastal counties catch a heavy share of them.

Retirees, remote workers, and young families all chase the same salt air.

Home builders chase them right down Highway 17.
