Congaree is the national park most people have never heard of, and that is a shame, because it protects the largest stretch of old-growth bottomland hardwood forest left in the country. The trees here are giants, including the world’s tallest loblolly pine at around 167 feet, growing out of a floodplain you can tour on a boardwalk without getting your feet wet. Add free admission and the famous synchronous fireflies, and you have one of the best-value parks in the system.
Below are 15 things to do at Congaree, ranked and grouped from the easy boardwalk highlights to the wilder paddling and backcountry. Each item lists the trailhead, distance, difficulty, and the best time to go, which matters here because flooding and mosquito season both shape the experience.

The Boardwalk and Easy Walks
1. Walk the Boardwalk Loop
Trailhead: Behind the Harry Hampton Visitor Center. Distance: 2.4-mile loop. Difficulty: Easy, elevated and partly accessible. Best time: Morning, any season.
The signature walk of the park, an elevated boardwalk that loops through the heart of the old-growth forest while keeping you above the mud and water. It is the easiest way to stand among the giant trees, and the interpretive signs explain what makes this floodplain so productive. Do this first to understand the forest before you go deeper.

2. Hike the Bluff Trail
Trailhead: Near the visitor center. Distance: 1.8-mile loop. Difficulty: Easy. Best time: Any time, good when lower trails flood.
A short loop on slightly higher ground, which means it stays dry when the floodplain trails are underwater. It runs through pine and hardwood forest and connects to the longer trail system. It is the reliable option when the river is up and the boardwalk’s lower sections are wet.
3. Hike the Weston Lake Loop
Trailhead: From the boardwalk. Distance: 4.4-mile loop. Difficulty: Easy to moderate. Best time: Drier months, fall and winter.
A step beyond the boardwalk into the real forest, this loop passes Weston Lake, an oxbow of the old river channel, and some of the biggest trees in the park. You may spot otters or wading birds at the water. It is the best way to get the full old-growth feel without committing to a long backcountry day.
4. Hike the Fork Swamp Trail
Trailhead: Connects from the main trail system. Distance: Part of the longer trail network. Difficulty: Moderate, can be wet. Best time: Drier months.
A quieter route through swamp forest that sees far fewer visitors than the boardwalk. It floods often, so it is best in the drier seasons and after checking conditions at the visitor center. This is where you trade easy walking for solitude among the trees.
5. Hike the Kingsnake Trail
Trailhead: South Cedar Creek Road. Distance: up to 11.7 miles round trip. Difficulty: Moderate, frequently floods. Best time: Fall and winter, drier conditions.
The park’s premier birding and wilderness trail, running deep into remote forest along Cedar Creek. It is prone to flooding and can be hard to follow when wet, so check conditions and bring a map. For hikers who want the wildest land in the park on foot, this is the one.
On the Water
6. Paddle Cedar Creek
Put-in: Bannister Bridge or South Cedar Creek Road. Distance: Varies by route. Difficulty: Easy to moderate. Best time: Moderate water levels, spring and fall.
The best way to experience Congaree is from the water, paddling the tea-colored Cedar Creek under a canopy of giant trees. The marked canoe trail winds through the old growth, and you will likely see turtles, herons, and maybe an otter. Bring your own boat or book a guided trip, and check the water level, since too high or too low both cause problems.
7. Tube or Float Cedar Creek
Put-in: Cedar Creek access points. Difficulty: Easy to moderate. Best time: Warm months with safe water levels.
On a warm day you can float a slow stretch of Cedar Creek and let the current carry you under the canopy. It is a relaxed way to cool off and see the forest from water level. Check with rangers on conditions first, because flow and obstacles change with the season.
8. Paddle the Congaree River Blue Trail
Route: Congaree River Blue Trail. Distance: a 50-mile designated water trail. Difficulty: Moderate, multi-day potential. Best time: Spring and fall.
A designated water trail on the larger Congaree River, running 50 miles from Columbia down past the park. You can paddle a section as a day trip or string together an overnight with backcountry camping. It is the way to see the river that gives the park and the forest their name.
Wildlife and Night Magic
9. See the Synchronous Fireflies
Where: The forest near the boardwalk. When: Roughly mid to late May, by lottery. Difficulty: Easy.
For about two weeks each spring, Congaree’s fireflies blink in unison, one of only a few places in the world where this happens. Demand is so high the park runs a lottery for the viewing event, with a limited number of vehicles allowed in each evening. The lottery opens in early April for the May event, so plan well ahead if you want to see it.
10. Go Birding
Where: The boardwalk, Kingsnake Trail, and Cedar Creek. Difficulty: Easy to moderate. Best time: Spring migration.
The old-growth forest is a haven for birds, with the bright yellow prothonotary warbler a signature sight in the swamp. The Kingsnake Trail is the park’s top birding route, but you will see plenty right from the boardwalk. Spring migration brings the most variety, so come early in the morning.
11. Go on an Owl Prowl
Where: Ranger-led program, check the schedule. Difficulty: Easy. Best time: Evening, when offered.
Rangers lead occasional evening programs to listen and look for the park’s owls, especially the barred owl whose call echoes through the forest at dusk. It is a great way to experience the swamp after dark with someone who knows it. Check the visitor center schedule, since these run seasonally.
12. Take a Ranger or Wellness Program
Where: Visitor center and boardwalk. Difficulty: Easy. Best time: Check the current schedule.
The park runs ranger-guided walks and a forest wellness series that uses the quiet old growth for mindful, slow-paced time among the trees. They are a thoughtful way to connect with the forest beyond just walking through it. Programs change seasonally, so see what is on when you visit.
Overnight and Beyond
13. Go Backcountry Camping
Where: Backcountry zones and the two designated campgrounds. Difficulty: Moderate. Best time: Fall through spring. Permit required.
Spending a night in the forest, with the frogs and owls calling, is the deepest way to experience Congaree. The park has two front-country campgrounds and allows backcountry camping with a free permit. Come outside peak mosquito season, and check the flood forecast before you commit to a low site.
14. Volunteer or Join a Workday
Where: Throughout the park, via the park volunteer program. Difficulty: Varies. Best time: Check the schedule.
If you want to give back, the park runs volunteer days for trail work, cleanups, and citizen science. It is a hands-on way to know the forest and help protect it. Reach out through the visitor center or the park website to find the next opportunity.
15. Plan Around the Mosquito Meter
Where: Harry Hampton Visitor Center. Difficulty: Easy. Best time: Read it before every visit.
Congaree has a famous mosquito meter at the visitor center, ranging from mild to war zone, and it is only partly a joke. The bugs can be serious from late spring into summer, so bring repellent and long sleeves, and consider visiting in the cooler months. Checking the meter is a fun ritual and genuinely useful planning.
Planning Your Congaree Visit
Fees and Reservations
Congaree is free to enter, with no entrance fee and no timed-entry system, which makes it one of the best-value national parks. The exceptions are the synchronous firefly event, which uses a paid lottery in spring, and backcountry camping, which requires a free permit. Reserve campgrounds and firefly passes through Recreation.gov.
How Many Days You Need
A half day covers the Boardwalk Loop and a ranger program, which is enough for many visitors. A full day lets you add the Weston Lake Loop and a paddle on Cedar Creek. Two days, plus a backcountry permit, lets you camp and explore the wilder trails and the river.
Getting Around and Conditions
This is a floodplain, so trails outside the boardwalk and Bluff loop flood regularly, sometimes for weeks. Always check current conditions at the visitor center before heading onto the lower trails or the water. The park sits about 20 miles southeast of Columbia, an easy drive, and the visitor center is the hub for everything.
Where to Stay
The park has two simple campgrounds, Longleaf and Bluff, both reservable through Recreation.gov. For hotels and restaurants, nearby Columbia has everything you need and is only a short drive away. There are also state parks and public lands destinations in the surrounding area for more camping options.
When to Go
Fall through early spring is the sweet spot, with cool weather, fewer bugs, and lower water on the trails. Mid-May brings the firefly event for those who win the lottery. Summer is hot, humid, and buggy, so save the lower trails for the cooler months and check the mosquito meter before any warm-season visit.
