Congaree National Park
Harry Hampton Visitor Center, Hopkins, SC
Near Columbia
Walk out onto the boardwalk at Congaree and the first thing you notice is how big everything is. This is a floodplain forest, a low, wet woodland along the Congaree River where some of the tallest trees in the eastern United States grow straight up out of the dark, spongy ground. Bald cypress trees push knobby knees up through the water, loblolly pines soar past a hundred and fifty feet, and the whole green ceiling closes overhead like the roof of a cathedral. People sometimes call it an American Amazon, and standing under it, you understand why.
This is a national park, protected as one in 2003, and it guards something rare: the largest intact stretch of old-growth bottomland hardwood forest left anywhere in the southeastern United States. Old-growth means the trees were never logged, so many of them are ancient and enormous, a living record of what the whole region once looked like. The park floods often, and that is the point. Every flood carries in fresh nutrients that feed these giants. Come in the cool months and you can walk it dry; come in late spring and, on the right nights, the forest floor blinks with thousands of fireflies flashing all at once.

The Park
Congaree is a bottomland hardwood forest, which is a fancy way of saying a woodland on low, flat ground beside a river that floods on and off through the year. The Congaree and Wateree rivers spill over their banks and spread thin across the forest floor several times a season, sometimes ten times a year. Instead of drowning the forest, those floods feed it. They leave behind rich sediment and water that let the trees grow to record sizes. This is the largest stretch of old-growth bottomland hardwood forest left in the country, meaning it was never cut down, so the trees here are old, tall, and huge.
The stars of the forest are the champion trees. A champion tree is the biggest known example of its kind, and Congaree holds a remarkable number of them, including some of the tallest loblolly pines, water tupelos, and bald cypresses on record. Several rank among the tallest trees of their species in the East. The park protects roughly a hundred and seventy square miles of this floodplain, and much of it is quiet, trackless swamp where the loudest sound is often just wind in the high canopy or a barred owl calling somewhere out in the trees.
The easiest way in is the elevated Boardwalk Loop, a raised wooden walkway that carries you out over the swamp without getting your feet wet. It winds past cypress knees and still, tea-colored water stained brown by fallen leaves, right under those towering trees. Beyond the boardwalk, dirt trails push deeper into the forest interior for people who want more, and Cedar Creek offers one of the best ways of all to see the place: from a canoe or kayak, drifting quietly beneath the giants.
How to Enter
- Main Entrance at the Harry Hampton Visitor Center, off National Park Road near Hopkins, is open year-round and is the only vehicle entrance. It leads straight to the visitor center, the parking area, and the start of the Boardwalk Loop, and the whole park is free to enter.
- From Columbia, South Carolina's capital, the park is only about twenty miles southeast. Follow local roads out through Hopkins to National Park Road, roughly a thirty-minute drive. Coming from Interstate 77 or Interstate 26, both of which pass through Columbia, work your way toward Hopkins and Gadsden and follow the brown park signs the last few miles in.
Things to Do
- The Elevated Boardwalk Loop is the signature walk, a raised wooden path about two and a half miles around that carries you out over the flooded forest floor and right under the tallest trees. It is the easiest and most popular way to see the swamp, and much of it is accessible.
- Paddling Cedar Creek by canoe or kayak is the quiet way to see Congaree, drifting a marked water trail beneath the cypress and tupelo where wildlife is easiest to spot. The park offers guided canoe tours in season, and they fill up fast.
- The Weston Lake Loop is a longer dirt trail, a little over four miles, that leaves the boardwalk crowds behind and pushes into the forest interior past an oxbow lake, a curved pond left behind when the river changed course.
- The Harry Hampton Visitor Center is the place to start: rangers there share the current flood and mosquito conditions, trail maps, and the schedule for guided walks and paddles.
History
The park takes its name from the Congaree people, a Native American nation who lived along this river long before Europeans arrived and who gave the river, and later the park, its name. Disease and displacement in the colonial era scattered the Congaree, but their name endures on the land, the water, and this forest, and the park honors that connection.
In the centuries that followed, these dense, flooded woods became a refuge for people escaping slavery. Freedom-seeking enslaved people, sometimes called maroons, hid in the swamps of the Congaree, where the water, the mud, and the tangled forest made them hard to find and hard to follow. Living in these bottomlands took deep knowledge of the land, and for some it was a path to lasting freedom. That quiet history is part of why the park matters, not just for its trees but for the people who once relied on them.
The forest survived because it was hard to log. The same floods that feed the trees made it difficult and costly to haul timber out, so the big old-growth stands were mostly spared while forests all around them fell. By the 1960s and 1970s, though, logging finally threatened these giants, and a grassroots campaign led by local conservationists rose up to save them. Their effort worked: Congaree Swamp became a national monument in 1976.
Protection grew from there. In 2003 the site was redesignated Congaree National Park, dropping the word swamp because the land is really a floodplain forest rather than a true swamp. Much of the park is also protected as wilderness, and the wider region has been recognized as a globally important biosphere. Today rangers, scientists, and volunteers keep measuring and mapping the record trees, and the park remains one of the few places where you can walk beneath old-growth hardwoods that were never cut.
Little-Known Facts
- Congaree is free to enter. It is one of the national parks that charges no entrance fee at all, so there is no gate booth and no pass to buy.
- The park is famous for its synchronous fireflies. For a couple of weeks in late spring, thousands of a special firefly species flash their lights on and off at the same time, one of only a few places in the country where this happens.
- Those aren't really cypress roots you see poking out of the water. They are called cypress knees, woody knobs that grow up from a bald cypress's roots, and scientists still debate exactly what they do for the tree.
- The dark, tea-colored water is stained brown by tannins, natural chemicals that leach out of fallen leaves, the same thing that colors a cup of black tea.
- The park holds a striking number of champion trees, meaning record-size examples of their kind, including some of the tallest pines and hardwoods in the eastern United States.
- Congaree floods on purpose. The flooding is what keeps the forest alive, delivering fresh nutrients several times a year, so the trails going underwater is a normal, healthy part of the cycle here.
- The visitor center posts a mosquito meter, a sign that rates the day's mosquito level from one to six, so you know what you are walking into before you leave the parking lot.
- Much of the park is protected as federal wilderness, and the wider area is recognized as an international biosphere reserve for its rare old-growth habitat.
Plan Your Visit
- The park is free. There is no entrance fee.
- The Harry Hampton Visitor Center is open daily and is the place to check current flood and mosquito conditions before you head out.

Frequently asked questions
Is there an entrance fee for Congaree National Park?
No. Congaree is free to enter, one of the national parks that charges no entrance fee at all. There is no gate booth and no pass to buy, so you can drive in, park, and walk the boardwalk without paying anything. Some guided programs and canoe tours may require a reservation, but general entry is free.
What is the Boardwalk Loop, and can you see the big trees from it?
The Elevated Boardwalk Loop is a raised wooden walkway about two and a half miles around that carries you out over the flooded forest floor without getting your feet wet. It is the easiest and most popular way to see the park, winding right under the towering bald cypress, loblolly pines, and hardwoods that Congaree is known for, past cypress knees and dark, still water. Much of the boardwalk is accessible.
Does the park flood, and can the trails be underwater?
Yes, and often. Congaree is a floodplain forest, and the Congaree and Wateree rivers spill over their banks several times a year. Those floods are what feed the giant trees, so flooding is a normal and healthy part of the park. When the water is high, parts of the boardwalk and the dirt trails can be underwater or closed. Always check current conditions with the visitor center or the park website before you go.
How bad are the mosquitoes at Congaree?
They can be intense, especially in the warm, wet months from late spring through early fall. The park is so mosquito-prone that the visitor center posts a mosquito meter that rates the day from one to six. Bring insect repellent, wear long sleeves and pants when it is buggy, and if you want to avoid the worst of it, visit in fall or winter.
What are the synchronous fireflies, and when can you see them?
For a couple of weeks in late May and early June, a special firefly species in the park flashes its lights on and off all at once, filling the dark forest with a coordinated light show. Congaree is one of only a few places in the country where this happens, so the event is very popular and access may be managed on peak nights. Check the park website before you go, since the exact timing shifts a little each year.
Can you canoe or kayak in the park?
Yes. Cedar Creek is a marked water trail that lets you paddle a canoe or kayak beneath the old-growth trees, one of the quietest and best ways to see the forest and its wildlife. The park offers guided canoe tours in season that require a reservation, and they fill up quickly. You can also bring your own boat and paddle the creek on your own when conditions allow.
What is the best time of year to visit Congaree?
Fall and winter are often the best time. The cooler months mean far fewer mosquitoes, and the bare canopy opens up clearer views of the towering trees. Spring is beautiful too, especially for the firefly show in late May and early June, though the bugs pick up. Summer is hot, humid, and buggy, so plan for early mornings and plenty of repellent if you come then.
How much time do you need at Congaree?
You can walk the full Elevated Boardwalk Loop and see the signature big trees in about two hours. To add a longer trail like the Weston Lake Loop or a paddle on Cedar Creek, give it most of a day. Many visitors treat it as a half-day stop paired with a visit to nearby Columbia.
Are pets allowed in the park?
Yes, leashed pets are allowed on the trails and the boardwalk at Congaree, which is friendlier than many national parks. Keep your dog on a short leash, bring water, and never leave a pet in a hot vehicle. Be aware that the boardwalk can flood, and check the park website for the current pet rules before you visit.
Is there lodging or camping inside the park?
There is no lodge or hotel inside Congaree, but the park does have two campgrounds for tents, and backcountry camping is allowed with a permit. For a bed and a hot shower, Columbia sits only about twenty miles away with the widest range of places to stay, and there are smaller options closer to the park as well.
