You can walk under 170-foot trees for free at this overlooked South Carolina national park

Where the tallest trees in the East still stand

South Carolina has one national park, and most people have never heard of it.

Congaree sits about 20 miles southeast of Columbia, covering 26,000 acres of old-growth bottomland hardwood forest, the largest intact stretch of this forest type left in the country. Admission is free.

The trails are flat. The trees are taller than 17-story buildings.

It’s one of the least-visited national parks in the country, and that gap between what it is and how few people know about it is part of what makes it worth the drive.

The Congaree people, maroon communities and loggers who shaped this land

People have lived in and around this forest for at least 10,000 years. The Congaree people were here long before European settlers arrived.

During the era of slavery, enslaved people fleeing nearby plantations disappeared into the dense floodplain and built maroon communities, living for years as free people hidden inside the wilderness. Cypress logging companies moved in from 1898 to 1914.

By the 1950s, a journalist named Harry Hampton started pushing to save what was left.

When logging threats returned in 1969, the Sierra Club and local groups launched a grassroots campaign that eventually led Congress to establish Congaree Swamp National Monument in 1976. It became a full national park in 2003.

It floods 10 times a year and that’s what makes it so alive

The old name had one thing wrong. Congaree isn’t a swamp.

Swamps stay underwater. This is a floodplain, a low-lying stretch of land along rivers that floods and drains in cycles.

The Congaree and Wateree Rivers wash over roughly 80 percent of the park about 10 times a year, depositing nutrients and sediment each time. That flooding is the engine behind everything you’ll see here.

It’s what drives the trees to grow so tall, what carves the oxbow lakes, and what keeps reshaping the forest floor. The boardwalk lets you watch the whole cycle play out without getting your feet wet.

Fifteen national champion trees live here and one is 169 feet tall

The canopy at Congaree ranks among the tallest temperate deciduous forest canopies left in the world.

The park holds the tallest known examples of 15 tree species and the highest concentration of champion trees anywhere on the continent.

The national champion loblolly pine stands 169 feet tall, roughly the same height as a 17-story building. Bald cypress trees here are more than 500 years old, with trunks that measure over 26 feet around.

Walk through a stand of them and you’ll feel the scale shift. You’re not looking up at trees anymore.

You’re looking up at a ceiling.

Six feet above the floodplain on a 2.4-mile elevated boardwalk

The Boardwalk Loop Trail runs 2.4 miles and sits about six feet off the forest floor, making it wheelchair accessible and passable even when the ground below is flooded.

It winds past massive bald cypress trees with their distinctive knees poking up through the water around them.

About two miles in, it brings you to Weston Lake, an oxbow lake that the Congaree River cut off and abandoned roughly 2,000 years ago. Pick up an interpretive brochure at the visitor center before you head out.

Check the NPS website first for current conditions, since sections of the boardwalk have been updated recently.

Twenty-five miles of trails push deeper into 22,000 acres of wilderness

Past the boardwalk, the park opens up into more than 25 miles of trails threading through 22,000 acres of designated federal wilderness.

The Weston Lake Loop covers 4.6 miles and follows Cedar Creek, where river otters show up regularly along the banks. The Kingsnake Trail stretches 11.1 miles and tracks deeper into the forest along the same creek.

The Bates Ferry Trail follows a colonial-era road once used by river ferries and draws serious birders year-round. All the trails run flat because of the floodplain terrain, but water levels can rise fast.

Check conditions before you go.

Paddle 15 miles of blackwater under a cypress canopy

Cedar Creek cuts through the middle of the park as a blackwater stream, dark with tannins leached from decaying leaves, slow-moving and quiet under the tree cover.

The Cedar Creek Canoe Trail runs about 15 miles from Bannister Bridge to the Congaree River.

The creek connects to the larger 50-mile Congaree River Blue Trail, a designated paddling route that runs all the way from Columbia.

You’ll need to bring your own canoe or kayak, as no rentals are available inside the park. Bring a compass and a map.

The side channels called “guts” branch off without warning and can send you in circles.

For two weeks in May, fireflies flash in perfect sync after dark

Every spring, synchronous fireflies of the species Photuris frontalis emerge across the park.

For about two weeks starting in mid-May, they flash in unison as part of their mating ritual, thousands of them blinking together across the dark forest floor.

They’re one of only a few synchronous firefly species found in North America, and scientists are still working out how they coordinate the timing across such wide stretches of habitat.

The event draws thousands of visitors and runs on a lottery-based pass system.

The park closes to general visitors in the late afternoon during the viewing period to protect the habitat.

Bobcats, otters, alligators and 200 bird species call this place home

Deer, bobcats, river otters, coyotes, wild turkeys and armadillos move through the forest floor. Alligators live in the deeper sections of the Congaree River, though sightings are uncommon.

Feral hogs are here too, rooting through the soil and causing real damage to the habitat.

Barred owls call out during the day, which sounds odd until you walk under the canopy and understand why they lose track of the time.

Nearly 200 bird species have been recorded in the park, including bald eagles, osprey, great blue herons, and several species of woodpeckers.

Nine turtle species and a wide variety of snakes and amphibians round out the list.

Bald eagles and owls wait for you on the Bates Ferry Trail

Congaree holds official status as a Globally Important Bird Area, and the mix of deep forest, open water, and floodplain edge pulls in species from a wide range of habitats.

Barred owls, red-shouldered hawks, summer tanagers and red-bellied woodpeckers show up consistently. The Bates Ferry Trail and the Kingsnake Trail are the two best routes for serious birding.

The Fork Swamp Trail leads to an oxbow lake where you can watch bald eagles and osprey work the water.

One more thing worth knowing: leashed dogs are allowed on all park trails, which puts Congaree ahead of most national parks on that count.

Camp for free under 500-year-old trees tonight

Camping in the park costs nothing, but you’ll need a free permit from the visitor center.

The Longleaf Campground near the entrance has 10 individual sites and four group sites, each with a fire ring and picnic table.

If you want to go deeper, backcountry camping is available on foot or by kayak into the wilderness areas. All camping is tent-only.

The Harry Hampton Visitor Center has exhibits, an introductory film, and up-to-date trail and water conditions.

Rangers lead free guided walks every Saturday throughout the year, which is a good way to see the forest with someone who knows where to look.

A forest that looks different every single time you visit

What makes Congaree worth coming back to is that it doesn’t stay the same.

Every flood reshapes the floor, shifts the creek banks, and drops a new layer of sediment around the roots of trees that have been standing since before the American Revolution.

Free admission and flat terrain mean it’s accessible for visitors of all ages. The closest cities are Columbia, Charlotte and Charleston, all within driving distance.

Bring water, bug spray and sturdy shoes. The forest will take care of the rest.
