Somewhere under a mountain lake in South Carolina, old roads and houses still sit on the bottom. Scuba divers can swim right over them because the water is so clear.
I can’t stop thinking about that, and it’s only one of the surprises hiding in the state’s parks.
One spot has a Moorish-style castle built for a sculptor, and another has a cast-iron lighthouse that was moved inland in pieces.
Then there are the cabins and shelters built by Depression-era work crews in the 1930s, many still in use today.
You can sleep in history and still be close to a swimming lake or a quiet beach.
I love that a few hours of driving can take you from salt marsh and shell-covered trails to granite peaks and waterfalls.
So which one gets your next free weekend, and how many can you squeeze into 2027?
1. Myrtle Beach State Park
A mile of beach with no high-rises behind it sounds impossible on the Grand Strand.
Yet here it is, backed by a maritime forest that somehow survived the boom around it.
History buffs get a bonus, since this was South Carolina’s first state park, opening in 1936. The Civilian Conservation Corps built it, and several of their original buildings are still in use.
Start your morning on the fishing pier, where people cast lines, go crabbing, and watch for wildlife. A bait shop sits right on site, so forgetting your supplies isn’t a disaster.
Kids will want time at the Nature Center, which has saltwater aquariums and live animals. Afterward, stretch your legs on the Sculptured Oak Nature Trail through the shady woods.
Planning to stay over? The campground has 278 sites, and six rental cabins sit near the beach.
Weekends can fill up fast, and the park sometimes closes temporarily when it hits capacity. Try arriving before 10 a.m. or after 2 p.m. to dodge the rush.
Trails also close from November through January for maintenance, so plan hikes for other months. The beach, thankfully, doesn’t take a winter break.
Address: 4401 S Kings Hwy, Myrtle Beach, SC 29575.
2. Huntington Beach State Park
Not many beach trips come with a castle tour, but this one does. Atalaya, a Moorish-style winter home, was built between 1931 and 1933 for sculptor Anna Hyatt Huntington and her husband, Archer.
Archer designed it to stand up to hurricanes, and Anna used it as her sculpting studio. Today it’s a National Historic Landmark, open for self-guided tours with a separate admission fee.
Birders, pack your binoculars. More than 300 bird species have been recorded here, making it one of the top birding spots on the East Coast.
The freshwater lake is a reliable place to spot alligators, so keep a respectful distance. Over at the Nature Center, saltwater touch tanks let you meet smaller, friendlier locals.
Three miles of undeveloped beach give you room for long walks and fishing. You can also cast a line from the jetty if surf fishing isn’t your style.
Camping includes 173 standard and full-hookup sites, plus six rustic tent sites for visitors who prefer a more traditional camping experience. In September, the Atalaya Arts and Crafts Festival brings artists to the castle grounds.
Weekend crowds can trigger temporary closures, so arrive early or later in the afternoon. Your parking spot and your patience will thank you.
Address: Murrells Inlet, SC 29576, United States.
3. Edisto Beach State Park
Some shells here are older than the pyramids, and you can walk right up to them. The Spanish Mount Trail leads to a Native American shell midden dating back to about 2000 BC.
That’s just one stop on the state’s longest system of ADA-accessible hiking and biking trails. More than four miles wind through maritime forest, so bring a bike if you have one.
Edisto is one of only four oceanfront state parks in South Carolina. Its 1,255 acres mix beach, salt marsh, and forest, which gives the place a slow, easy pace.
You get two very different camping moods here. The Beach Campground sits by the ocean, while the Live Oak Campground hides in the forest with marsh views.
Prefer walls and a roof? Seven furnished cabins sit on the salt marsh, about a mile and a half from the ocean.
Curious kids will like the Environmental Learning Center, with live animals and exhibits about the ACE Basin. Anglers can try surf fishing or work the marsh instead.
The Civilian Conservation Corps built the park in the 1930s, and many of those buildings remain in use. It’s a beach trip with a side of history.
Address: 8377 State Cabin Rd, Edisto Island, SC 29438.
4. Hunting Island State Park
A lighthouse that can be taken apart and moved sounds like a toy, but it’s real. Its cast-iron sections were designed for relocation, and crews moved it in 1889 because of beach erosion.
The tower was first built in 1859 and rebuilt in 1875 after the Civil War. Climbing is paused during repairs, but the exhibit buildings at the site are open.
Don’t let that stop you, because the rest of the island is a showstopper. You get five miles of beach, a saltwater lagoon, and an ocean inlet on a semitropical barrier island.
Head to the 950-foot fishing pier for views over Fripp Inlet. The Nature Center has live animal exhibits if you need a break from the sun.
The flat, well-marked trails work for hiking and mountain biking. Check for ticks afterward, though, since the woods are thick.
Campers can pick from 100 sites with water and electric hookups or 25 rustic tent sites. There’s also one furnished cabin if you’d rather skip the tent.
Fun bit of trivia: the island was once called Reynolds Island. Hunters flocked here in the 1800s, and the new name stuck.
Address: 2555 Sea Island Pkwy, St Helena Island, SC 29920.
5. Table Rock State Park
The Cherokee called this granite dome Sah-ka-na-ga, meaning Great Blue Hills of God. Stand at the bottom of the 3,100-foot mountain, and the name makes sense.
Ready to earn your view? The Table Rock Trail climbs 3.4 strenuous miles to the summit, so pack water and plenty of snacks.
Prefer something gentler? Easier trails lead to Carrick Creek Falls, and the park has more than 10 miles of trails overall.
Two lakes give you options after the hike. Lake Pinnacle has a roped-off swimming area in summer, plus kayak, canoe, and pedal boat rentals at the boathouse.
Anglers can fish both lakes for bass, bream, catfish, and trout in colder months. Just bring a South Carolina fishing license.
The Civilian Conservation Corps built much of the park in the 1930s. Nine of the cabins are CCC-built, and the Gaines Lodge hosts monthly bluegrass jam sessions.
Hikers register at the Concessions Area before hitting the trails. The park is also the southern trailhead for the long Foothills Trail, if your legs want more.
Construction has closed the Nature Center and trailhead restrooms for now. Check the park’s updates before your trip so nothing surprises you.
Address: 158 E Ellison Ln, Pickens, SC 29671.
6. Devils Fork State Park
Swimming over a flooded valley is a strange idea, and that’s what makes Lake Jocassee so cool.
Duke Power filled the valley in 1973, and divers can still spot old roads and houses below.
This park is the only public access point to the lake. The water is famously clear, which is why scuba divers, swimmers, and trout anglers love it.
Four mountain streams and several waterfalls feed the lake. Many of those falls can only be reached by boat, so a paddle trip becomes a treasure hunt.
No boat? Kayaks, canoes, and paddleboards are available to rent right in the park.
Visit in spring and walk the Oconee Bell Nature Trail. It’s known for the rare Oconee bell wildflower, which shows up in spring.
Overnight choices range from 20 furnished villas to standard RV sites and rustic walk-in tent sites. Adventurous campers can even paddle to a boat-in campground on an island.
Weekends and holidays get busy, and lines can be long. Reserve day-use parking ahead of time so you don’t end up turned around at the gate.
Address: 161 Holcombe Cir, Salem, SC 29676.
7. Paris Mountain State Park
Greenville’s drinking water once came from the lakes in this park.
Those old reservoirs, built in the late 1800s, now serve as swimming and paddling spots instead.
Lake Placid is the star, with a swimming area and seasonal canoe, kayak, and pedal boat rentals. Self-serve kayak rentals are available daily, but private boats aren’t allowed.
Trail lovers, you’ve got more than 15 miles of hiking and mountain biking paths. The Sulphur Springs Trail and Lake Placid Trail are good places to start.
The Civilian Conservation Corps left its mark here in the 1930s. The old 1936 bathhouse is now the Park Center, with exhibits about the area.
Look for the amphitheater built in 1940, too. The park’s CCC structures are listed on the National Register of Historic Places.
Campers get 39 paved sites with water and electric hookups, plus five trailside campsites. Groups can book Camp Buckhorn, which has 10 primitive cabins and a lodge.
Fun name fact: the mountain honors early settler Richard Pearis. The spelling ended up looking a lot more French.
Since it rises right above the city, it’s an easy escape after a Friday workday. You can be on a trail before dinner.
Address: 2401 State Park Rd, Greenville, SC 29609.
8. Dreher Island State Park
Why settle for one island when a park can spread across several?
This one stretches over multiple islands on Lake Murray, with lake views in many directions.
Campers get the best seats in the house. Many campsites and camper cabins sit right on the water, so your morning view is the lake.
Bringing a boat? The park has solid boat ramps, which make launching easy for anglers and weekend boaters.
Kayaking and canoeing are popular here, too. Paddling lets you explore the shoreline at your own pace.
Fishing is a big draw here. You can cast from the shoreline, a boat, or the park’s private fishing hole.
Land lovers aren’t left out. Walking trails and nature hikes give you a break from the water, and kids can burn energy at the playground.
Trailer campers in particular will feel at home with sites that suit RV travel. The bathhouses are kept clean, which matters after a long day outside.
The park is open from dawn to dusk, while the park office operates daily from 8 a.m. to 5 p.m. Plan your arrival accordingly.
Lake Murray sits in the middle of South Carolina, making it an easy drive from several cities.
Address: 3677 State Park Rd, Prosperity, SC 29127.
9. Santee State Park
Bug spray belongs at the top of your packing list here, and that’s not a joke. The park has a buggy reputation, but the lake views make the swatting worth it.
The park sits on the shore of Lake Marion, a big draw for boating and fishing. A marina makes it easy to get out on the water and chase a catch.
Beach lovers can relax on a man-made sand beach. It’s a nice surprise if you thought sand was only for the coast.
The hiking trails stay on the easy side, so younger kids can keep up. Bikers will find cycling lanes, and the playground handles any leftover energy.
Campers can choose from campsites and rental cabins. Spacious RV sites come with water and electricity, and some have lovely water views.
Forgot something? A small park store can cover basics without a long drive into town.
Wildlife sightings happen here, and some critters come with a little attitude. Give them space, keep your snacks secured, and enjoy the show from a distance.
Pack a picnic and claim a table with a grill for lunch by the lake. Dogs are welcome too, so the whole crew can join.
Address: 251 State Park Rd, Santee, SC 29142.
10. Sesquicentennial State Park
A park name this long deserves a nickname, and even its web address shortens it to Sesqui.
Sesquicentennial means a 150th anniversary, which makes this the fanciest-sounding park on the list.
Fancy name aside, it’s a laid-back forested park right in Columbia. That makes it a handy weekend pick if you don’t want to spend hours in the car.
The lake is the center of the action. You can rent kayaks, canoes, or pedal boats and float around at your own speed.
On land, a bicycle loop and nature trails wind through the trees. A 2-mile shaded path is great for slow walks on hot afternoons.
Families, take note of the splash pad and playground. Pups get their own dog park, so nobody in the family feels left out.
Campers will find level, packed gravel sites, and some come with sewer access. Picnic shelters and grills make group cookouts simple.
Weekends draw the biggest crowds, especially Saturday and Sunday afternoons. Arrive in the morning to grab a good picnic spot before the rush.
It’s a sweet way to close out a South Carolina park tour. Big city, small escape, and a whole lot of shade.
Address: 9564 Two Notch Rd, Columbia, SC 29223.
